Frequently Asked Questions - LXER6 Hobart

How to level the LXER6 dishwasher?

Use a carpenter's level placed diagonally on the rack rails. Screw or unscrew the adjustable feet to level the appliance front to back and side to side. Cover the threads with the provided black rubber caps.

What water pressure is needed for the LXER6?

Dynamic pressure must be between 15 and 65 psi (103.4 to 448 kPa). If it exceeds 65 psi, install a pressure regulator. If it is lower, operation may be affected.

How to prime the chemical dispensers after changing containers?

Priming starts automatically at the next cycle. It lasts 60 seconds. If products are not detected after 3 attempts, the alarm flashes. Ensure tubes are fully inserted to the bottom of the containers and containers are not empty.

What to do if the display shows 'LOW RINSE TEMP'?

This message appears after 3 consecutive cycles with insufficient rinse temperature. Check the incoming water temperature. The appliance continues to operate. If the problem persists for 10 cycles, consult maintenance service.

How to start a manual descaling cycle?

In the management menu, navigate to 'DESCALE NOW', select YES. Remove the racks, clean the filters, ensure descaling product is present (for LXePR and LXeR, it is injected automatically). The cycle lasts 20 to 45 minutes.

Can I wash aluminum or silver items in the LXER6?

No, if your model is chemical sanitizing (LXeC or LXePR), sodium hypochlorite (bleach) attacks aluminum, tin, and silver. Avoid washing these materials.

How to clean the wash arms and filters?

Press START to drain the water. Open the door, remove the coarse and fine filters, clean them under water. Remove the wash and rinse arms (depending on model, knurled nut or side buttons), clean the nozzles with a toothpick. Reassemble everything.

Why does the dishes remain dirty after a cycle?

Possible causes: clogged filters, blocked wash arms, insufficient detergent, water temperature too low, incorrect loading. Check these points and clean the appliance. If the problem persists, contact Hobart service.

What is the recommended water hardness for the LXER6?

Recommended hardness is 3 grains per US gallon (20.58 ppm) or less. Beyond that, water treatment (softener) is advised to prevent scale buildup and improve wash performance.

How to set the wash cycle to economy mode?

In the management menu, enter code 1001. Navigate to 'WASH CYCLE' and choose between light, normal, or heavy. You can also activate the energy save mode (default setting 2 hours) to reduce standby consumption.

GENERAL

The LXe Series dishwashers are fully automatic, front-loading dishwashing machines. The LXe series machines are capable of doing 24 to 34 racks per hour, depending on model.

All LXe Series dishwashers shut down automatically 4 hours after last use to conserve energy.

All LXeH and LXeR dishwashers include Sense-A-Temp ^™ to insure proper hot water temperature during rinse.

Standard equipment includes two 20" x 20" racks, electronic controls, drain pump, rinse pump, chemical pumps, fill hose, and drain hose.

MODEL DESCRIPTION

LXeC, LXePR Fresh water rinse; low-temperature, chemical-sanitizing models for use with 6% sodium hypochlorite solution (bleach) as the sanitizing agent*.

Note: If 8.40% bleach is to be used, contact Hobart Service or your chemical supplier to change the sanitizer pump settings. (Charges may apply)

LXeH Fresh water rinse with a built-in 70°F rise booster heater. This allows an incoming water temperature of 110°F.

LXeR Fresh water rinse with an internal energy recovery unit and a built-in 70°F rise booster heater. Recommended incoming water temperature 55°F to 80°F.

* - Sanitizing agent must be used in accordance with the EPA-registered label use instructions.

INSTALLATION

UNPACKING

Immediately after unpacking the dishwasher, check for possible shipping damage. If this machine is found to be damaged, save packaging material and contact the carrier within 15 days of delivery.

LOCATION

Prior to installation, verify that the electrical supply agrees with the specifications on the machine data plate, which is located on the top of the door.

Steam generated from normal operation may escape from the door. Wood, laminates, veneers, etc. are unsuitable materials for use in areas exposed to dishwasher steam and detergents. Stainless steel or other moisture-resistant shields are recommended for surfaces adjacent to LXe sides and top.

LEVELING

The machine must be level to operate properly. Place the dishwasher in its operating location. Level the machine before any connections are made. Using a carpenter's level placed diagonally on the rack tracks, level the machine front to back and side to side by threading the adjustable feet in or out. After leveling the machine, cover the exposed threads of the adjustable feet with black rubber tubing supplied. (See separate instructions furnished with machine.)

WATER REQUIREMENTS

Proper water quality can improve ware washing performance by reducing spotting, enhancing effectiveness of labor and extending equipment life. Water conditions vary from one location to another. The recommended proper water treatment for effective and efficient use of this equipment will also vary depending on the local water conditions. Ask your municipal water supplier for details about your local water conditions prior to installation.

Recommended water hardness is 3 grains of hardness per gallon or less. Higher hardness may cause excessive formation of lime scale. Water hardness above 3 grains per gallon requires water treatment. Water treatment has been shown to reduce costs associated with machine cleaning, reduce deliming of the dishwasher, and reduce detergent usage in the dishwasher.

NOTICE High iron levels in the water supply can cause staining and may require an iron filter. High chloride levels in the water supply can cause pitting and may require a chloride removal system. Contact your local water treatment professional for proper water treatment.

Sediment may require a particulate filter. Dissolved solids may require water treatment such as a water softener, reverse osmosis system, etc. Contact your local water treatment professional for proper water treatment.

If an inspection of the dishwasher or booster heater reveals lime buildup after the equipment has been in service, water treatment is recommended. If a water softener is already in place, ensure there is a sufficient level of salt. Contact your local Hobart Service office for specific recommendations.

A water hammer arrestor (meeting ASSE-1010 Standard or equivalent) should be installed (supplied by others) in the common water supply line at the service connection.

The plumber connecting this machine is responsible for making certain that water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher. This "flush-out" is necessary to remove all foreign matter, such as chips (resulting from cutting or threading of pipes) pipe joint compound from the lines; or, if soldered fittings are used, bits of solder or cuttings from the tubing. Debris, if not removed, may lodge in the dishwasher's plumbing components and render them inoperative. Manual valves or solenoid valves fouled by foreign matter and any expenses resulting from this fouling are NOT the responsibility of the manufacturer and associated repair costs are not covered under warranty.

Water supply requirements are as follows:

MODEL

TEMPERATURE

LXeC 120°F Minimum

LXePR 120°F Minimum

LXeH 110°F Minimum

LXeR 55°F Minimum, 80°F Maximum

NOTE: On LXeR installations, if cold water supply temperature is consistently above 80^ F or if excessive water vapor or steam is entering the room after the condensing cycle is complete, contact Hobart Service to increase condensing time.

Required flowing water pressure to the dishmachine is 15-65 PSIG. If pressures higher than 65 PSIG are present, a pressure regulating valve must be installed in the water line to the dishmachine (by others). If flowing pressure is less than 15 psi, improper machine operation may result. All LXe models are equipped with a pumped rinse system; therefore, a water pressure gauge is not required and is not supplied with the machine.

NOTICE The water pressure regulator must have a relief bypass. Failure to use the proper type of pressure regulator may result in damage to the unit.

A manual shutoff valve (not supplied) should be installed upstream of the fill hose to accommodate servicing the machine.

It is recommended that a line strainer (not supplied) be installed in the supply line between the manual shutoff valve (not supplied) and the connection point on the machine. Make plumbing connections with 12 " minimum copper piping OD ( 34 " recommended), with a 34 " male garden hose fitting (not supplied). See installation diagrams, pages 14-17.

PLUMBING CONNECTIONS

DETERGENT AND RINSE AID

Use only commercial-grade detergents recommended by your chemical professional. Do not use detergents formulated for residential dishwashers.

The detergent and rinse aid pump "ON" times are factory-set. If adjustments are required, contact your local Hobart Service Office or your chemical supplier.

Place the detergent and rinse aid containers (which are obtained from an independent supplier) in a location where the delivery tubes will reach them.

Remove the detergent bottle cap and put the red delivery tube in the detergent container.

Remove the rinse aid bottle cap and place the blue delivery tube in the rinse aid container.

Be sure to push the delivery tube standpipes completely to the bottom of each container. Check to make sure there are no obstructions or kinks in the delivery tubes.

CHEMICAL SANITIZER (LXeC & LXePR)

NOTICE Items such as pewter, aluminum and silver will be attacked by sodium hypochlorite (bleach). Therefore, chemical-sanitizing dishwashers should not be used to wash such items.

On models LXeC & LXePR, the chemical sanitizer pump is factory-set for use with 6% sodium hypochlorite solution.

NOTICE If 8.40% sodium hypochlorite solution is to be used, contact your local Hobart Service Office.

On LXeC models, place a 1-gallon bottle of 6% or 8.40% sodium hypochlorite solution (bleach) in a suitable location no higher than 10 inches off the floor. Do not pre-mix sanitizing solution with water or any other liquid.

On LXePR models, place a sanitizer approved for potable water rinse machines in a suitable location no higher than 10 inches off the floor. Do not pre-mix sanitizing solution with water or any other liquid.

⚠ WARNING Never premix a wetting agent with the sanitizing solution. Mixing may cause hazardous gas to form.

Remove the sanitizer bottle cap and place the white delivery tube in the sanitizer container. Be sure to push the delivery tube standpipe completely to the bottom of the container. Check to make sure there are no obstructions or kinks in the delivery tube.

Frequently check your sanitizer bottle to make sure there is a sufficient chemical supply.

CHECKING SANITIZER CONCENTRATION

Verify there is sufficient chemical supply in the sanitizer bottle and that the delivery tube standpipe is inserted completely to the bottom of the chemical container. Place a glass rack, with glasses, in the machine.

On LXePR models, the PuriRinse feature must be deactivated to properly check the sanitizer concentration. To deactivate PuriRinse, press and hold the WASH key for five seconds until wash cycle starts.

On LXeC models, press the WASH key to run a cycle. At the end of the cycle, open the door.

Follow the directions precisely that are on the litmus paper vial and test the water on the surface of the bottom of the glasses. Concentration should be 50 p.p.m. minimum to 100 p.p.m. maximum.

If reading is incorrect, contact your local Hobart Service Office or chemical provider for adjustments.

DELIMING SOLUTION

All LXePR and LXeR models are equipped with an automatic deliming system. At installation, a qualified Hobart Service technician or your chemical supplier must adjust the total water hardness setting to properly set the delime intervals.

Remove the deliming agent bottle cap and put the black delivery tube in the container.

Be sure to push the delivery tube standpipe completely to the bottom of the container. Check to make sure there are no obstructions or kinks in the delivery tube.

PRIMING CHEMICAL PUMPS

When a chemical becomes empty, the priming operation starts automatically the next time the machine is turned on or a wash cycle is started. Note that the initial prime time for all pumps (Detergent, Rinse Agent, and Sanitizer) is 60 seconds. If the chemical is not sensed within 60 seconds, the add chemical indicator will flash. After the chemical is sensed, the indicator in the display turns off; and the pump continues to prime for 10 seconds to allow the chemicals to reach the machine. If all chemicals are empty, the sanitizer will prime first followed by detergent. Only one chemical pump will run at a time.

If chemicals are not sensed after three consecutive priming operations, the add chemical indicator will flash and priming is cancelled. The next time a wash cycle is started, the add chemical indicator will continue to flash. Verify that the chemical bottles are not empty and that the delivery tube standpipes are inserted completely to the bottom of the containers.

The priming operation can be reset by turning the dishwasher off, then back on.

If the chemical bottles are not empty and the delivery tube standpipes are inserted correctly, then the chemical sensor or pumps may have malfunctioned; contact your local Hobart Service Office.

WARNING

Do not premix other chemicals and sodium hypochlorite (liquid bleach). "dous gas to form.

MAINTENANCE

Maintenance and regular care is important to maintain optimal results with your Hobart warewasher.

DELIMING

⚠ WARNING Deliming solution, rinse agents or any other kind of acid must not come in contact with bleach or rinse solution containing bleach used in chemical-sanitizing machines. Mixing may cause hazardous gas to form. This entire procedure must be followed step by step for safe and satisfactory results.

NOTICE Do not allow the deliming agent to remain in the machine longer than recommended by the deliming agent manufacturer.

DELIME THE DISHWASHER ON A REGULAR BASIS AS REQUIRED. The regularity will depend on mineral content of the supply water. Deliming should be done when you can see clear signs of lime deposits (a white, chalky substance) on the inside walls and on the wash arms. All LXe models are equipped with an automatic delime cycle reminder. It is recommended that deliming be done when DELIME RECOMMENDED is lit. LXePR and LXeR models are equipped with an internal delime pump which will automatically pump the required amount of deliming agent into the unit.

If deliming is necessary, a deliming agent (such as Lime-A-Way ^® or LSR ^® ) should be used for best results.

After the preprogrammed number of cycles has expired, the control will indicate the delime request by displaying DELIME RECOMMENDED and will prompt 'Would you like to delime now?'. You must enter 'Yes' or 'No' to proceed with a delime cycle or to continue with normal machine operation. If 'No' is selected, the machine will continue to notify the operator at each start-up and power down until the delime cycle is completed. To delime the unit:

1. Press the MENU/DOWN Arrow key until the '>' symbol is shown to the left of 'Yes' and press the ENT key.
2. Remove dish rack from machine.
3. Remove strainers from machine and clean. Replace strainers and close door.
4. On LXePR and LXeR models, ensure delimer chemical container is not empty. Be sure to push the delivery tube standpipe completely to the bottom of the container. Check to make sure there are no obstructions or kinks in the delivery tube.
5. Press ENT key to enter the delime mode. The machine will drain and refill with fresh water.
6. On LXeC and LXeH models, the display will prompt 'ADD DELIME AGENT' once the fill cycle has completed. Open the door and add deliming agent. (Carefully follow supplier's instructions.) The sump holds approximately 3 gallons of water. On LXePR and LXeR models, the unit will automatically pump in the required amount of deliming agent during the fill cycle.
7. On LXeC and LXeH models, after the deliming agent has been added, close the door. Press the ENT key to continue the cycle. The machine will enter the wash mode for 10 minutes, then will begin two rinse and drain operations. On LXePR and LXeR models, the unit will automatically enter the wash mode for 10 minutes, then will begin two rinse and drain operations after the fill cycle is complete.
8. After the delimming operation is completed, power to the control will be turned off.
9. Inspect the interior of the machine for lime deposits. If necessary, another delime cycle can be initiated by entering the Manager Programming Mode.

LUBRICATION

The pump motor has permanently sealed bearings and requires no lubrication.

TROUBLESHOOTING

This section outlines various symptoms and possible causes that may be encountered in the event of abnormal machine operation. If symptoms persist after possible causes have been checked, service may be required.

Symptom Possible Causes
No machine operation (no display). 1.	Machine OFF - turn machine ON.2. Blown fuse or circuit breaker off at power supply.3. Cord not plugged in (corded models only)
No machine operation (with display). 1.	Display: "DOOR OPEN" - open and close door. If problem persists, contact your local Hobart Service Office.2. See "Machine will not fill or will not fill high enough".
Dishes not clean. 1. Strainers clogged	causing inadequate water supply to pump - clean according to instructions. (See CLEANING.)2. Obstruction in wash arm(s) or wash arms will not turn - clean according to instructions. (See CLEANING.)3. Wash and/or rinse arms will not turn - check that they spin freely.4. Detergent dispenser may be clogged.5. Soil quantity - scrape dishes before cycle.6. Improper rack loading. (See PREPARATION.)7. Low water - check water supply.8. Water temperature too low - note wash temperature on display during WASH; should be above 120°F for chemical sanitizing machines and above 150°F for high temperature machines.9. Incoming water supply turned off.
Spotting of silverware, glasses, or dishes.	Improperly loaded racks.Water temperature too low.Improper type or concentration of detergent - contact your chemical representative.Hard water - install a water softener; use a rinse agent.Insufficient fill - check water supply.
Chemicals not feeding. 1. Low on chem	chemicals - check levels.Air leak at feeder hose connections - check insertion of quick connect fittings and wire ties at tube to tube connections.Tubes kinked - check for smooth bends.
Food soils remain in dishwasher.	Follow daily cleaning instructions. (See CLEANING.)
Appearance of rust in machine. 1. Ens	ure steel wool is not used to clean machine.May be due to high iron content in water supply.
Unexpected results on dishes.	1. Etching - usually caused by any combination of high temperatures, soft water, soft glass, or high alkaline washing solutions.2. Tarnishing - avoid washing silver, silver plates, and pewter in chemical sanitizing machines.3. Pitting - stainless steel may pit with lengthy contact of foods containing salt, fruit juices, vinegar, etc. Wash immediately.4. Black or gray marks - may have been rubbed with aluminum.5. Brown stains - may be due to high iron content in water supply.6. Chipping - improper loading or ware is too delicate.7. Fading of china patterns - usually due to high water temperature and strong detergent. Check that china is dishwasher compatible.8. Wooden ware damage - avoid washing in dishwasher.9. Rust on cast iron - seasoning is lost in dishwasher. Avoid washing in dishwasher.10. Plastic ware distortion - high temperatures. Check plastic ware's instructions.
Low temperature readings.	1. Low water supply temperature - make sure it meets the recommended minimum temperature.2. Rapid cycle use - if incoming water temperature is low and cycle use rate is high, the hot water supply may be insufficient to meet the demand.3. Heavy ware load cools wash water - do not overload racks.4. Booster heater or sump heater set low - contact your local Hobart Service Office.
Machine will not fill or will not fill high enough.	1. Low water pressure - check for clogged hose strainer; ensure the site water pressure meets minimum flow pressures.2. No water flow - main water supply valves may not be working.
Machine fills too high or leaks from door.	1. Machine not level. (see LEVELING.)2. Fill solenoid valve leaking - power the dishwasher OFF; if water continues to flow into the machine, contact your local Hobart Service Office.
Machine will not drain. 1. Drain pipes restricted - check dishwasher drain line for kinks; ensure proper drain rate is allowed from plumbing.2. Power machine OFF. Wait several seconds and then power back ON. Repeat this procedure twice if necessary. If problem persists, contact your local Hobart Service Office.
Some water occasionally drips out of rinse arms (high temperature dishwashers only).	This is normal due to expansion of water being heated in the booster tank.
