Frequently Asked Questions - T-350 Express DEXTER

How to install the Dexter T-350 Express washing machine?

Ensure the machine is placed on a level, sturdy floor. Connect to 400V, 3-phase power supply and to hot and cold water lines with 3/4" hoses. The drain must be connected to a suitable drain system. Refer to the installation manual for detailed steps.

What detergent should I use?

Use a low-sudsing detergent suitable for commercial washing machines. Avoid over-sudsing as it can affect performance. Liquid or powder detergents are acceptable, but follow the dosage guidelines on the detergent package.

How to clean the filter?

The filter is located at the bottom front of the machine. Turn off the machine and disconnect power. Remove the filter cover, pull out the filter, and rinse it under running water. Clean monthly to maintain proper drainage.

What do error codes mean?

Error codes are displayed on the digital panel. Common codes: E01 - water inlet issue, E02 - drain problem, E03 - motor error. Refer to the manual for a full list. Reset the machine by turning it off and on; if persists, contact service.

How to drain water manually?

In case of power failure, manually drain the machine using the emergency drain hose located behind the filter cover. Place a bucket, remove the cap, and let the water drain. Avoid hot water to prevent burns.

What to do if the machine stops mid-cycle?

Check for error codes on the display. If no code, ensure the door is closed properly. The machine may pause due to overload or water level issues. Reduce the load and restart the cycle. If the problem continues, consult a technician.

How to perform a test cycle?

Press and hold the Test button (if available) for 5 seconds, or follow the manual instructions. The machine will run a short cycle to verify operation. Make sure the drum is empty before running a test.

What are the spin speed settings?

The T-350 Express offers adjustable spin speeds. Typical settings include 300, 400, and 500 rpm. Select the appropriate speed based on fabric type. Higher speeds extract more water but may cause wrinkling.

Can I wash delicate fabrics?

Yes, use the Delicate program which uses lower agitation and spin speed. Place delicate items in net bags for extra protection. Avoid washing heavy items together with delicates.

Where to find spare parts for the Dexter T-350 Express?

INSTALLATION INSTRUCTIONS

All washers must be installed in accordance with all local, state and national building, electrical, plumbing and other codes in effect in the area.

WARNING - THESE INSTALLATION AND SERVICING INSTRUCTIONS ARE FOR USE BY QUALIFIED PERSONNEL ONLY. TO AVOID INJURY AND ELECTRICAL SHOCK DO NOT PERFORM ANY SERVICING OTHER THAN THAT CONTAINED IN THE OPERATING INSTRUCTIONS, UNLESS QUALIFIED.

FOUNDATION REQUIREMENTS

This machine is designed for use on or over bare concrete floor - not to be used above combustible flooring. The washer must be securely bolted and grouted to a substantial concrete floor, or mounted and grouted upon a suitable base that is securely bolted and grouted to a substantial concrete floor. CARE MUST BE STRESSED WITH ALL FOUNDATION WORK TO INSURE A STABLE UNIT INSTALLATION, ELIMINATING POSSIBILITIES OF EXCESSIVE VIBRATION. All installations must be made on sound concrete floors, 6 inches (150mm) or thicker. Anchor bolts or expansion anchors must be of a quality grade and a minimum of 5/8 inch (16 mm) diameter.

MOUNTING

A concrete pedestal or steel-mounting base that elevates the machine approximately 8 inches (200 mm) above the floor level is recommended to provide easy access to the loading door. Allow a minimum of 24 inches (600mm) of clearance behind the rear of the machine, to provide access for motor removal. Refer to Fig. 1-1 and 1-2 for machine bolt-down dimensions.

If an elevated concrete pedestal is desired, it should be embedded into the existing floor. Anchor bolts should be 5/8" x 8" (16 mm x 200 mm), grade 8 or better, headed by a 4 inch (10 cm) square fish plate and should protrude 1 7/8" (48 mm) above the finished surface of the pedestal. EXPANSION ANCHORS ARE NOT RECOMMENDED FOR USE IN CONCRETE PEDESTALS, BECAUSE THE ANCHORS ARE TOO CLOSE TO AN EDGE, CAUSING IT TO BREAK OUT. (See Fig. 1-1 and 1-3.)

Separate hot and cold water lines must be provided, maintaining 30 psi to 120 psi (207 kPa to 827 kPa) water flow pressure. A 140F (60C) degree hot water supply is recommended for best washing results. Do not exceed 180F (82C) degree water temperature.

DRAIN

The drain outlet tube at the rear of the machine is 2 14 inches (57 mm) in diameter. Any drain hose used must be lower than the drain valve to assure proper draining.

ELECTRICAL

WARNING SHUT OFF POWER AND WATER BEFORE OPENING ANY SERVICE PANELS.

The Dexter T-350 single/three-phase 208-240VAC 60 Hz washing machines are intended to be permanently installed appliances. No power cord is provided. The machine should be connected to an individual branch circuit not shared by lighting or other equipment. The connection should be sheathed in liquid tight flexible conduit, or equivalent, with conductors of the proper size and insulation. A qualified technician should make such connections in accordance with the wiring diagram. (Suggest a minimum wire size of 12 ga.)

TO MAKE ELECTRICAL CONNECTIONS: Disconnect all power to the washer. Remove the top panel of the washer and locate the power terminal block near the back of the control compartment.

If power is 208-240-3PH-60Hz, connect L1, L2, L3 and ground. If there is a high leg it must be connected to L3.
If power is 208-240-1PH-60Hz, connect L1, L2 and Ground.

NOTE: It is important that the grounding screw next to the power terminal block TB-1 be connected to a good external ground.

FUSING REQUIREMENTS:

SINGLE- and THREE -PHASE 208-240VAC MODELS - 15 AMP TIME-DELAY (DUAL ELEMENT) FUSE (or equivalent circuit breaker)

CONTROLS TRANSFORMER

The controls transformer is located inside the control trough and steps a range of 208 to 240 volts down to 115 volts. There are two terminals on the controls transformer for the primary (incoming) power. Use the terminal marked "208V" for power supplies between 208 and 219 volts. Use the terminal marked "240V" for power supplies between 220 and 240 volts.

BLACK/BLUE WIRE DO NOT MOVE OR REMOVE THIS WIRE. BLACK/RED WIRE CHOOSE THIS TERMINAL FOR 208V TO 219V BLACK/RED WIRE CHOOSE THIS TERMINAL FOR 220V TO 240V

CHECKOUT

After all mounting, plumbing and electrical work is completed; the washer should be run through a cycle and checked for water leaks and proper functioning.

The cylinder should turn in a counterclockwise direction (viewed from the front of the machine) during intermediate spin and final spin. If spin is clockwise, the T1 and T2 motor wires going to T1 and T2 on the variable frequency drive should be swapped. Remove power to the machine before swapping wires.

OPERATING INSTRUCTIONS - STARTING THE WASHER

A. Load the clothes into the cylinder and latch the door securely. Be sure clothing does not get caught between the door gasket and tub front when closing the door. Maximum load is 20 pounds clothes, dry weight. Do not load the washer with more than 20 lbs.

B. Select the appropriate cycle temperatures for the load being washed.

C. Add low sudsing powdered detergent into the "detergent" compartment of the automatic dispenser on the top of the washer. If desired add fabric softener to the "fabric softener" compartment. Use the amount of fabric softener as recommended by the manufacturer.

If liquid wash products are used in the "detergent" compartment, they must be added at the beginning of the wash cycle.

If the machine is set for pre-wash, washing products can be added to the round opening of the dispenser or put in with the clothes when loading the washing machine.

D. Insert coins, tokens or debit card to meet the displayed vend price. The display will count down the amount needed to meet the vend price. Once the vend price is met, the display will read "PRESS START" and the start button LED will blink. If the door is not closed and latched, the display will read "CLOSE DOOR" and the control will wait until the door is latched to continue. Pressing the start button will begin the cycle and activate the ON light. The display will show the remaining cycle time in minutes. The clothes door will lock and remain locked until the end of the cycle.

END OF CYCLE

When the cycle is complete a 3-second tone will sound and the display will read "CYCLE DONE THANK YOU" until the door is opened. The door can now be opened. Leave the clothes door open when the machine is not in use.

This machine is equipped with a Safety Door Lock that locks the door closed from when the cycle is started until the cycle is complete. The door lock prevents opening the door for up to 3 minutes if the power is interrupted during the cycle.

The Emergency Stop button pauses the washer and allows the door to be opened during the cycle after the Safety Door Lock releases. When the Emergency Stop button is pressed an alarm will sound and the display will begin counting down and read "STOP 3", "STOP 2", "STOP 1". If the button is released before 3 seconds elapse, the alarm will stop and the cycle will continue normally. If the Emergency Stop is held down for 3 seconds, the display will count down and the washer will begin stopping movement and water flow and begin draining water from inside the washer. Though the machine may stop wash movement quickly, it may take up to 3 minutes for the door to unlock.

During that time the alarm will continue to sound and the display will read "STOPPING".

When the alarm stops, the door may be opened. The washer may be restarted by closing and latching the door, and pressing the Start button. If the washer was stopped more than once before the final extract, the cycle will be cancelled. If the washer was stopped during final extract, the cycle will be ended. If the washer is stopped for more than 1 hour, the cycle will be terminated.

PROGRAMMING THE WASHER CONTROL

The washer control can be programmed to prompt the user for alternate vend prices, change washer cycle times, temperatures and many other options. This can be accomplished in two ways:

1. Manual programming utilizing the "Start", "Hot", "Warm" and "Cold" buttons
2. USB download of a customizable User File. For instructions on using the USB download feature, please contact your local Dexter distributor or visit dexterlive.com.

MANUAL PROGRAMMING:

The washer must be in idle mode for the manual programming menus to be accessed. Idle mode is when the washer is not actively running a wash cycle and the vend price is displayed on the screen.

To enter the manual programming mode, the top of the washer must be unlocked and lifted slightly (it may be necessary to remove the screws for the soap box). The programming button is then pressed for 1 second. The control should display "PROGRAMMING".

See the figure below for the location of the programming button in relation to the USB port (The USB port is exposed when the washer top is lifted).

USB PORT SHOWN WITH WASHER TOP LIFTED CONTROL PROGRAMMING BUTTON (SHOWN IN CUT-AWAY VIEW, ACTUAL LOCATION IS INSIDE THE CONTROL PANEL) Quarters Only

When manual programming mode is entered, the "Start", "Hot", "Warm" and "Cold" buttons perform alternate functions.

Button Name	Alternate Function in Programming Mode
Start	Becomes the action to accept the displayed option or the “Enter” key
Hot	Becomes the action to move UP through displayed options (Press & hold for accelerated scrolling)
Warm	Becomes the action to move DOWN through displayed options (Press & hold for accelerated scrolling)
Cold	Becomes the action to move back a step (1 press) or EXIT from programming mode (press for 3 seconds)

These alternate functions allow the user to move through a menu of options to choose various programmable settings. The figure below shows the top level menu. Choosing an option from the top level menu will then display the next level of options (the sub menu).

Quick Test Option:

When the Quick Test Option is chosen, the washer will begin a shortened wash cycle without the displayed vend price being met. The purpose of this shortened cycle is to test all major components for proper operation.

Error Codes should all function normally during this test. The display will show customer prompts in a similar way to a normal wash cycle. Exceptions to this are that the "ADD BLEACH" prompt will not occur because of reduced cycle time. Final Extract speed is specific to the customer's programming.

Rapid Advance Option:

Similar to the Quick Test, when the Rapid Advance Option is chosen, the washer will begin a wash cycle without the displayed vend price being met. However, in this case, it will be a normal default cycle with an additional feature available. The "Start" button LED will flash, prompting the user that, when pressed, the washer shall rapid advance to the next step in the cycle. The display will show "ADVANCE" when the cycle is advancing. The water level needs to be empty before this advance occurs. During the time waiting for the tub to empty, the "ADVANCE" prompt will be held on the display and the start pushbutton LED stops flashing. The Rapid Advance shall allow the tub to empty of water and the tub to stop before beginning either spin or the next bath.

The Rapid Advance mode can be exited by pressing the programming button. This will end the cycle. When the Rapid Advance mode is used, the cycle time will no longer be correct. By skipping steps with Rapid Advance, the door may not open immediately at the end of the cycle.

Error Code Historical Log:

The last five occurring error codes will be stored in the control with a time and date stamp. The purpose of this option is only to observe the history of these code occurrences (no changes can be made).

The time is based off the Real Time Clock, but potentially shifted by the user's manual programming changes (Shift Hours option) and/or network time override. As additional error codes occur, the oldest of the five logged codes is cleared from memory.

Prices Option:

This option allows the user to set values for coin acceptor inputs and to set the vend price. It also allows the user to return the values to factory defaults. After changing prices using the "Up" or "Down" buttons, the "Enter" button must be pressed again for the control to store the changes that have been made.

1. "RIGHT COIN" and "LEFT COIN" are the two possible inputs from coin acceptors.
2. "SET VEND" is the actual Base Vend Price (or Vend Price A) that is shown on the control display.

To reset either the coin acceptor inputs or the vend price to factory default, press "Enter" when the "DEFAULT" prompt is shown. Press "Enter" again when the "RESET" prompt is shown to confirm the action.

    G --> L["FREE - 00.01-99.99 (00.01 increments)"]
    H --> M["RESET"]

Temp Pricing Option:

The Temperature Pricing option allows for the user to prompt the customer for varying vend prices based on the water temperature the customer selects. If a value other then 0 is programmed for either the "WARM ADDER" or "HOT ADDER", the feature becomes active. The programmed value is added to the base vend price when that particular water temperature is chosen.

When the customer adds coins to meet the adjusted vend price and starts the washer, the temperature selections available to the customer are limited to those with vend prices equal to or less than the amount entered.

    C --> E["FREE - 00.01-99.99 (00.01 increments)"]

Cycles Option:

This option allows the user to set the bath time and spin time for the "Wash" bath. It also allows the user to set bath time, water temperature and spin time for "Rinse" and "Final rinse" baths. (Water temperature for the "Wash" bath is chosen by the customer using the "Hot", "Warm" and "Cold" buttons on the front of the machine). For the "Final Spin" it also allows the user to set the spin speed (see additional description below).

It also allows the user to return the values to factory defaults. To reset all values in the Cycles option to factory default, press "Enter" when the "DEFAULT" prompt is shown. Press "Enter" again when the "RESET" prompt is shown to confirm the action.

1. "Final Spin" is the spin that occurs after all selected baths & intermediate spins have been completed. It is a higher spin speed than previously occurring intermediate spins. The benefit of this higher spin speed is that more water is extracted from the wash load, which minimizes the drying time needed. However, in some cases, if the Dexter installation guidelines are not followed properly, it may be necessary to reduce the spin speed of the "Final Spin".

The "Final Spin" can be adjusted in increments of 10 G for washers with a 100G maximum spin speed and increments of 20 G for washers with a 200G maximum spin speed. The factory default "Final spin" speeds are the maximum values.

Model	Adjustable Final Spin Range
T-300	60G to 100G
T-350	60G to 200G
T-400	60G to 100G
T-450 or T-450 SWD	60G to 200G
T-600	60G to 100G
T-750	60G to 200G
T-900	60G to 100G
T-950	60G to 200G
T-1200	60G to 100G
T-1450	60G to 200G

1. "Delay Fill" is meant to be used in applications where the amount of available water pressure is limited. In these cases, the washer may not be able to fill the tub in sufficient time to allow for effective washing performance.

When the "Delay Fill" option is "On", the water valves shall be turned on, the washer shall agitate, but the cycle time shall be paused. The washer shall continue in this state until the proper water level is reached. Once the proper water level is reached, the cycle shall continue. A single selection of "On" or "Off" shall apply to all baths in the cycle. The factory default setting is "Off".

1. "Delay Spin" is meant to be used in applications where the amount of drain capacity is limited. In these cases the washer cannot empty the tub in sufficient time to allow for a spin cycle to occur.

When a time value (other than 0) is programmed for the "Delay Spin" option, the end of each bath will be extended by the selected time. Therefore, extra time will be allowed for the drain valve to be open and compensate for slow drain capacity. The factory default setting is 0 seconds.

1. "Default Temp" allows the user to choose which water temperature ("Hot", "Warm", or "Cold") will be active during Idle mode. The customer can, of course, choose other temperatures for the wash bath based on other options described in this manual.

Plus Cycle Options:

The "Plus Cycle" options allow for the user to prompt the customer for varying vend prices based on additional wash baths chosen. In general, the user can program the additional wash baths in a similar manner to what was described in the "Cycles" Options section.

It also allows the user to return the programmable values to the factory default setting. No plus cycle options are active using the factory default. To reset all values in the Plus Cycles option to factory default, press "Enter" when the "DEFAULT" prompt is shown. Press "Enter" again when the "RESET" prompt is shown to confirm the action.

1. "Pre-Wash"- If the user programs a "Cycle Time" for "Pre-Wash" other than 0 ("No Cycle"), the feature becomes active. However, the customer will not be prompted to pay an additional vend price for "Pre-Wash" unless the user programs the Price to a value other than 0 ("Free"). With the "Pre-Wash" feature active, an additional bath and, optionally, an additional spin, will occur before the standard Wash bath described in the Cycles Options section.

With the "Pre-Wash" feature active and a "Price" value programmed, the customer will be prompted to add additional coins if they wish to purchase the "Pre-Wash" feature. This will occur after they have entered coins to meet the Base Vend price. If the customer does not meet the vend price of the "Pre-Wash" feature, the prompt will time out and the "Pre-Wash" bath will not occur.

1. "Extend Wash"- If the user programs an "Extend Time" for "Extend Wash" other than 0, the feature becomes active. However, the customer will not be prompted to pay an additional vend price for "Extend Wash" unless the user programs the Price to a value other than 0 ("Free").

With the "Extend Wash" feature active, the standard Wash bath described in the Cycles section will be extended for the additional time selected. With the "Extend Wash" feature active and a "Price" value programmed, the customer will be prompted to add additional coins if they wish to purchase the "Extend Wash" feature. This will occur after they have pressed the "Start" button to begin the normal Wash cycle. If the customer does not meet the vend price of the "Extend Wash" feature, the prompt will time out and the additional time will not be added to the Wash bath.

1. "Extra Rinse"- If the user programs a "Cycle Time" for "Extra Rinse" other than 0 ("No Cycle"), the feature becomes active. However, the customer will not be prompted to pay an additional vend price for "Extra Rinse" unless the user programs the Price to a value other than 0 ("Free").

With the "Extra Rinse" feature active, an additional bath and, optionally, an additional spin, will occur after the standard "Final Rinse" bath described in the Cycles Options section. With the "Extra Rinse" feature active and a Price value programmed, the customer will be prompted to add additional coins if they wish to purchase the "Extra Rinse" feature. This prompt will occur during the standard

"Final Rinse" bath. If the customer does not meet the vend price of the "Extra Rinse" feature, the prompt will time out and the "Extra Rinse" bath will not occur.

Settings:

The "Settings" options allow for the user to make various programming changes to change how the control operation affects the customer. See below for detailed information on each next level option.

1. "Decimal Point"- If the user programs the Decimal Point to "OFF", control display will not show a decimal point on any vend price values. The factory default is "ON".
2. "Sounds"- If the user programs the Sounds to "OFF", the control will not sound the enunciator at the end of a wash cycle. The factory default is "ON".
3. "Password"- If the user programs the password to any value other then 0000, the control will prompt the user to enter a password (the programmed value) before manual programming can be accessed. The factory default is "0000" (no password).

a. Note that if the user forgets the Password, it can be reset to factory default (no password), by performing a hard reset on the control. Please refer to the appropriate section of this manual to understand how to perform a hard reset.
b. The individual digits of the Password can be set by using the "Up" or "Down" buttons to change the number that is flashing. Once the desired number is chosen for a single digit, press the "Enter" button to move to the next one. Once all four desired digits are chosen, the "Enter" button must be held down for 3 seconds to confirm that the complete password should be set.

1. "Language"- The control uses English for the default language of the customer prompts. Alternatively, the user can choose Spanish or French for the customer display prompts. However, all other prompts, such as Manual Programming, USB Programming and any Error Codes will still display in English.
2. "Shift Hours"- This feature allows the user to shift the time used by the control from the time kept internally by the control. The control uses a Real Time Clock (RTC) to internally track the time and date. The RTC continues operation even if the control loses external power. The RTC is set for Central Standard Time and no daylight savings. Because the machine may be located in another time zone, the user can choose to create an alternate time & date that tracks in parallel to the RTC. When this alternate time is chosen, or shifted from the RTC, the alternate time will be used to, for example, track error code occurrences and set time-of-day pricing changes.

a. The hours in "SHIFT HOURS" can be set by using the "Up" or "Down" buttons to change the number that is flashing. Once the desired hour shift is chosen, press the "Enter" button to move to the minutes. Once the hours and minute shift are both chosen, the "Enter" button must be held down for 3 seconds to confirm that the complete shifted time is set.

1. "Time"- The control uses a Real Time Clock (RTC) to internally track the time and date. The RTC continues operation even if the control loses external power. The RTC is set for Central Standard Time and no daylight savings. However, if a problem occurs and the RTC time is not accurate, it can be reset to the current time using this option.

a. The hours in "TIME" can be set by using the "Up" or "Down" buttons to change the number that is flashing. Once the desired hour is chosen,

press the "Enter" button to move to the minutes. Once the hours and minute are both chosen, the "Enter" button must be held down for 3 seconds to confirm that RTC is meant to be reset to the complete entry.

1. "Date"- Similar to "Time", if a problem occurs and the RTC date is not accurate, it can be reset to the current date using this option.

a. The day of the month in "DATE" can be set by using the "Up" or "Down" buttons to change the number that is flashing. Once the desired day of the month is chosen, press the "Enter" button to move to the month of the year. Once the desired month of the year is chosen, press the "Enter" button to move to the year. Once the day, month and year are all chosen, the "Enter" button must be held down for 3 seconds to confirm that RTC is meant to be reset to the complete entry.

1. "Drive Table"- The control knows what model of washer it is installed in based on various inputs including information it receives from the Variable Frequency Drive (VFD). However, because multiple VFD's can be used on the same model, depending on when it was manufactured, the "DRIVE TABLE" option is available. Any new washer should have the "DRIVE TABLE" programmed to the "CURRENT" option. However, in older washers that have been retrofitted with a new control, the "CLASSIC" option should be chosen. Contact your local Dexter distributor for more information.

To reset all values in the Settings options to factory default, press "Enter" when the "DEFAULT" prompt is shown. Press "Enter" again when the "RESET" prompt is shown to confirm the action.

TRANSIENT VOLTAGE SURGE SUPPRESSORS

Like most electrical equipment your new machine can be damaged or have its life shortened by voltage surges due to lightning strikes which are not covered by factory warranty. Local power distribution problems also can be detrimental to the life of electrical components. We recommend the installation of transient voltage surge suppressors for your new equipment. These devices may be placed at the power supply panel for the complete installation and don't require an individual device for each machine.

These surge protectors help to protect equipment from large spikes and also from small ongoing spikes in the power that occur on a day to day basis. These smaller surges can shorten overall life of electrical components of all types and cause their failure at a later date. Although they can't protect against all events, these protective devices have a good reputation for significantly lengthening the useful life of electronic components. Electronic components are helped to have a longer useful life when they are supplied with the clean stable electrical power they like.

We are including the following names and phone numbers of a few suppliers of these devices for those who don't currently have a source.
