Frequently Asked Questions - G4 ThermoPro Wilbur Curtis

How do I clean the G4 ThermoPro coffee maker?

Daily cleaning: Remove and wash the brew basket and carafe with warm soapy water. Wipe the exterior with a damp cloth. For deep cleaning, use a descaling solution per manufacturer instructions.

What type of coffee filter should I use?

Use commercial paper filters (size 4 or equivalent) or a reusable gold-tone filter. Ensure the filter is properly seated in the brew basket.

How do I program the timer on the G4 ThermoPro?

Press the PROG button, use the arrow keys to set the time, press PROG again to set brew time, and finally press START to activate the timer. The unit will brew at the set time.

Why is the coffee not hot enough?

Ensure the carafe is preheated with hot water before brewing. Check that the thermal carafe is properly sealed. If the issue persists, the heating element may need servicing.

Can I brew half a batch?

Yes, the G4 ThermoPro can brew smaller batches. Adjust the water volume accordingly, but ensure the water level covers the heating element. Use the pause & serve feature if needed.

How often should I descale the coffee maker?

Descale every 3 months or more frequently if you have hard water. Use a commercial descaling solution and follow the manual's instructions.

What does the 'Ready' indicator mean?

The 'Ready' indicator lights up when the water in the reservoir reaches the optimal brewing temperature (195-205°F). You can then start the brew cycle.

How do I replace the water filter?

Turn off the machine, remove the reservoir cover, take out the old filter, insert the new filter (soak in water first), and reassemble. Reset the filter indicator if applicable.

My coffee maker is leaking water. What should I do?

Check the brew basket is correctly inserted, the carafe is properly placed, and the spray head is clean. Inspect the water line for cracks. If the leak persists, contact service.

USB - Easy Programming

There are two methods for changing the default settings on G4 brewers. The settings can be programmed manually using the brewer touch screen, or automatically using the USB (Universal Serial Bus) data port on the side of the brewer. Using the USB connection and a flash drive easily reprograms the settings by simply copying data.

A flash drive can copy all of the settings from one identical G4 brewer to another. Doing so eliminates the need to program each step individually using the touchscreen. This process also makes it easy to quickly standardize the program settings on multiple G4 brewers.

Use a flash drive that supports USB 2.0 or above and has a type-A USB connection. The storage capacity must be 2 GB minimum.

IMPORTANT: The flash drive must be completely blank. Erase any existing files on the drive before starting the following process.

Uploading the Software to the Flash Drive

1 Make sure the brewer is on. Check to make sure that the brewer you are copying settings from is programmed as desired.
2 Open the cover on the USB port and insert the connector on the empty flash drive. The port is located on the right side panel of the brewer, near the top. The universal control module (UCM) will upload all of the setup data onto the flash drive. The yellow LED icon on the top left of the touchscreen will light indicating that data is transferring. This process will only take a second to complete.

Downloading the Software to the Brewer from the Flash Drive

1 Select the (identical) brewer you wish to make program changes to. The brewer must be on.
2 Plug the loaded flash drive into the USB port on the brewer. The data copied from the first brewer will automatically download, overwriting all the settings that were on the second brewer.
3 The red LED on the top left of the touchscreen will indicate that the download is in process. This will only take a second.
4 Once the download is complete, the UCM will reboot so that the changes take effect.
5 Remove the flash drive. The download is complete. The data on the flash drive can continue to be downloaded into as many identical brewers as needed.

USB File Transfer

This screen will be present whenever the USB flash drive is inserted, provided the brewer is not currently brewing.

The default action is "No Action". The UCM will always create a backup on the flash drive before downloading settings/recipes or a screen-saver.

If a firmware update is present on the flash drive, the firmware update procedure will be started before the screen is shown.

Scald and Burn Hazard - keep body parts clear of hot surfaces during troubleshooting.

IMPORTANT: If it is necessary to replace the G4 universal power module (UPM), always check all inlet, dump (brew), bypass* and dilution* valve coils for a short and replace the valve as necessary, before replacing the module. See the Valve Test Procedure, below to test for defective valves. *Some units do not have this function, see the ELECTRICAL SCHEMATIC.

Troubleshooting Guidelines

• If an error message appears on the display, consult the ERROR CODES section before troubleshooting.
• A brewer that is not level may not function properly. Make sure the brewer is properly leveled before proceeding.
• This troubleshooting guide identifies some, but not all, of the possible causes for common problems that can occur.
• Use this troubleshooting guide along with the appropriate ELECTRICAL SCHEMATIC.

Valve Test Procedure

Use a digital multi-meter to measure the resistance of valve coils.

Measure the resistance across the valve coil terminals with the wiring harness disconnected. Reverse the meter leads on the terminals and measure the resistance in the opposite direction. A resistance of less than 100 ohms, in either direction, indicates a shorted coil. The valve must be replaced.

If a shorted coil is not detected, test for an open coil:

1 Reconnect the valve terminals to the wiring harness.
2 Power up the brewer and test the valve using the diagnostics in section TG11.

Water Not Hot Enough

1 If the water heats, but is not hot enough, first check for the correct temperature setting on the control panel. Reprogram as necessary.
2 If the temperature setting is OK, and the actual water temperature does not match setting on the control panel, replace the temperature sensor.

Water Heats More Slowly Than Usual

1 Check for power across the terminals of the heating element(s). If power is being supplied, disconnect the heating element(s) and check for continuity. Replace a heating element if the resistance is too high (nominal resistance is 13 Ohms).
2 If there is no power to the heating element(s), check the wiring to any element that does not have the proper voltage across it. Also check for corroded connections anywhere between the power cord and the heating element(s).

Dispenser Overflows During Brewing

1 Check to make sure the control module (UCM) brew, bypass* and dilution* levels are set properly.
2 Check for a missing spray head. Replace as needed.
3 Make sure the dispenser is empty before starting the brew cycle. If not, empty it before brewing.
*Some units do not have this function, see the ELECTRICAL SCHEMATIC.

No Power - Display Not Lit

1 Make sure the circuit breaker to the circuit supplying power to the brewer is not tripped and is turned on.
2 On brewers with a power plug, make sure it is connected to the power receptacle.
3 Make sure that the main power toggle switch on the back panel is turned ON.
4 Verify that all wires from the power cord are properly connected inside the unit. Check to make sure the wires are not burned/overheated. Check chassis ground.
5 Check the low voltage input to the universal control module (UCM) from the transformer (see the ELECTRICAL SCHEMATIC). If there is power into the UCM, but the display is blank, the UCM is probably bad.
6 If there is no power into the UCM, trace the circuit back (using the wiring diagram) to the power cord to find out where power is lost. If there is power into the thermostat reset switch, but not out, see step 7.
7 If there is power into the thermostat reset switch, but not out, check to make sure that the water tank is not empty. If the tank is empty, the reset switch has probably opened up due to a low water level, go to Water Tank Does Not Fill. If there is water in the tank, but no power out, push in on the reset switch button to see if it restores power. If power is restored, check to make sure that the switch is not opening up at the wrong temperature (the switch should not open up at normal water temperatures). If there is still no power through the switch after pushing the button, replace the thermostat reset switch.

Brewer Does Not Start When Brew Button is Pressed

1 If Brewing appears on the display, check for faulty wiring and connections between the universal power module (UPM) and the valves.
2 If Brewing does not appear on the display, check for a faulty universal control module (UCM) or universal power module (UPM).

Water Too Hot (Boiling or Excessive Steaming)

IMPORTANT: Before proceeding, make sure that the control panel temperature is adjusted to compensate for higher elevations. Check the factory default temperature in the SPECIFICATIONS section. Reduce the temperature setting two degrees for every 1000 feet of elevation.

1 If Over Temp Sensor or Ready to Brew appears on the display and the water is too hot, go to Over Temp Sensor Error Message.
2 If the display reads Heating constantly, check the resistance across the leads of the temperature sensor. If the resistance is 10 k or more when the water is hot, check the sensor wire for corroded/poor connections at the universal power module (UPM). Also check the sensor for proper mounting to the tank. If the display still reads Heating when the water is hot, replace the temperature sensor.

Sensor Error Message

This error indicates a malfunction (open circuit) in the temperature sensor system. Once the malfunction is corrected, the error message must be cleared. To reset the brewer and return to normal operation, turn the toggle switch on the back of the brewer to the OFF position for 5 seconds, then back ON.

1 Check the resistance across the leads of the temperature sensor while it is disconnected from the universal power module (UPM). If an open circuit is measured (resistance above 200 k), replace the sensor.
2 If the sensor resistance is less than 200 k check the sensor wires for corrosion and reconnect them to the UPM. Afterward, if the error message comes back after resetting the control and power modules, replace the UPM.

Water Tank Overfills

1 Turn the toggle switch on the back of the brewer ON and OFF. If water continues to flow when the switch is in both positions, replace the inlet valve.
2 If water stop flowing to the water tank when the toggle switch is turned OFF and continues when the switch is turned back ON, remove the orange wire from the water probe on the tank. While power is ON, short the end of the orange wire to the metal surface on the outside of the tank. If the water tank stops filling when the orange wire is shorted to the tank, check for a corroded connection at the water probe.

3 If water does not stop flowing when the orange wire is shorted to the tank, check the tank ground connection and the continuity of the orange wire connecting to the universal power module (UPM). If both are OK, replace the UPM.

Water Tank Does Not Fill

IMPORTANT: No water or low water in the tank can cause the tank to overheat, resulting in the thermostat reset switch opening. If after correcting a tank fill problem there is no power to the control panel, push the reset switch button to reset.

1 Check to make sure the water supply is turned on. Check for a plugged water supply line or plugged inlet valve.
2 If there are no plugs in the water supply line, check for power across the inlet valve terminals. If power is being supplied, but there is no water flow, replace the inlet valve.
3 If power is not being supplied to the inlet valve, check the wires between the universal power module (UPM) and the inlet valve. Check for corroded connections.
4 If the wiring between the UPM and the inlet valve is OK, but there is no power to the inlet valve, remove the orange wire from the water tank probe. If the water tank starts to fill, replace the water probe. If the water tank does not start to fill, replace the UPM.

Coffee/Tea Too Strong

See Dispenser Not Filled To Normal Level During Brewing.

Dispenser Not Filled To Normal Level During Brewing

1 Check to make sure that the universal control module (UCM) brew, bypass* and dilution* levels are set properly.
2 Check to make sure that the flow rate and water pressure from the water supply line meet the minimum specifications for the brewer. See the SPECIFICATIONS section.
3 Check to make sure that the spray head is clean and free of debris. Clean or replace as needed. Also make sure that the spray head is correctly aligned and that the tubing is routed properly to allow for maximum water flow (no kinks).
4 Remove the brew basket and place a large container under the dump (brew) and dilution outlet points. Run a brew cycle and confirm that the dump (brew) valve, bypass* valve and dilution* valve open during the brew cycle. Check for flow through any exit point that is slow or non-existent. Not all valves open at the same time. If flow is restricted, check for obstructions in the related tubing or valve. If there are no obstructions, but flow through one particular valve is slow, it can be assumed that the particular valve is not opening all the way and should be replaced. If water does not flow at all through a particular valve during the brew cycle, check to make sure that power is being supplied to the valve in question. Replace any valve that is not opening when power is applied to the terminals. If power is not being supplied to the valve, check the wiring between the valve and the universal power module (UPM). If the wiring is OK, replace the UPM.

*Some units do not have this function, see the ELECTRICAL SCHEMATIC.

Dispenser Overflows All Of The Time

1 ?Check to see if water continues to flow from the spray head, the bypass* outlet or the dilution* spout when the toggle switch is turned OFF. Replace any valve that is stuck open. *Some units do not have this function, see the ELECTRICAL SCHEMATIC.
2 If one or more of the valves mentioned in step 1 turns on when the toggle switch on the back is ON and turns off when the switch is OFF, replace the universal power module (UPM).

No Water/Tea Flows From Brewer During Brewing

1 ?Make sure that the water supply is turned on.
2 Check to see if the water in the tank is level with the water tank probe? If not, see Water Tank Does Not Fill.
3 ?If the water tank is full, the water is hot and power is on, but NO water flows during a brew cycle, the problem is usually a bad universal power module (UPM). Run a brew cycle and check for power from the UPM to the dump (brew), bypass* and dilution* valves. If there is no power output, replace the UPM. *Some units do not have this function, see the ELECTRICAL SCHEMATIC.

Low Water Flow Warning

See Water Level Error Message.

Water Level Error Message

Water level fill error or overflow. This error message occurs when the inlet valve solenoid has been on too long during initial fill or tank refill. See the ERROR CODES section for the maximum times allowed. Once the malfunction is corrected, the error message must be cleared. To reset the unit and return to normal operation, turn the toggle switch on the back of the brewer to the OFF position for 5 seconds, then back ON.

1 ?Check to make sure that the flow rate from the water supply line meets the minimum flow rate specifications for the brewer. Also check the water pressure. See the SPECIFICATIONS section.
2 Check for blockage at the inlet valve inlet or outlet. Check for blockage in the tubing between the inlet valve and the water tank.
3 ?Check the water probe wire for an open condition or corroded connections.
4 ?If the probe connections are OK, cycle power to the unit by turning the rear toggle switch OFF, then ON. Check to see if power is applied to the inlet valve terminals. If power is applied to the terminals, but there is not water flow, replace the inlet valve.
5 ?Check for power from the universal power module (UPM) to the inlet valve. If the wiring is OK, replace the UPM.

"Internal Error 1" Message on Display

Check the wiring harness that connects from pins 4, 9 and 11 of the 14-pin connector on the universal power module (UPM) to pins 2, 3 and 6 of the 8-pin connector on the universal control module (UCM).

"Internal Error 2" Message on Display

The universal power module (UPM) and universal control module (UCM) have a mismatch in their settings. A firmware update is needed. See PROGRAMMING GUIDE.

Water Does Not Heat At All

• Check to see if the water level in the tank is in contact with the water level probe. If not, see Tank Does Not Fill. The water will not heat unless it is in contact with the probe.
  • If the water heats, but is not hot enough, see Water Not Hot Enough.
• If Ready to brew appears on the display, but the water is not hot, check the resistance across the leads of the temperature sensor. If the resistance is less than 10 k and the water is not hot, replace the temperature sensor. If the sensor resistance is above 10 k when the water is cool, replace the universal power module (UPM).

If Heating... appears on the display, but the water is not hot, follow the steps below. The following steps are performed with the rear toggle switch in the ON position.

1 Check for power across the terminals of the heating element(s). If power is being supplied, remove the wires and check for an open heating element.
2 If there is no power to the element(s), trace the circuit back (using the ELECTRICAL SCHEMATIC) to the power cord to find out where power is lost. If there is power into the solid state relay(s) (SSRs) but not out, see the following step. On units having two SSRs, be sure to check both.
3 If there is power into a SSR, but not out, check for 5 Vdc (nominal*) across the + and - pins of the SSR(s). If there is 5 Vdc across the + and - pins of the SSR(s), but no (or low) output voltage at a SSR output terminal, replace the SSR. If 5 Vdc is not being supplied from the UPM, but Heating... appears on the display, check the wiring from the UPM to the SSR(s). If the wiring is OK, replace the UPM.

Water Too Hot (Boiling or Excessive Steaming)

IMPORTANT: Before proceeding, make sure that the control panel temperature is adjusted to compensate for higher elevations. The factory setting is 200° F. Reduce the temperature setting two degrees for every 1000 feet of elevation.

1 If Over Temp Sensor or Ready to Brew appears on the display and the water is too hot, go to Over Temp Sensor Error Message.
2 If the display reads Heating constantly, first check to make sure that the temperature senor is attached tightly to the tank and that heat sink compound was used. A properly mounted sensor should have a resistance of around 7 k when the water is hot. If not, replace the sensor.
3 Check to see if the universal power module (UPM) constantly has +5 Vdc (nominal) output to the solid state relay (SSR), regardless of the resistance of the temperature sensor. If so, the UPM is probably bad.
4 If the UPM is working properly, check for a shorted SSR.

Over Temp Sensor Error Message

This error message indicates that the universal control module (UCM) has detected a water overheating problem. The universal power module (UPM) is reading a water temperature in the tank above 210° F. If the water temperature is too hot, but Heating... appears on the display, see Water Too Hot. Once the malfunction causing the error is corrected, the error message must be cleared. To reset the brewer and return to normal operation, turn the toggle switch on the back of the brewer to the OFF position for 5 seconds, then back on.

1 Check for 5 Vdc (nominal) across the + and - pins of the solid state relay (SSRs). If no power is applied to the SSR and the heating elements are always on, replace the SSR. On units having two SSRs, check both.
2 Turn off power to the brewer and allow the water tank to cool. Once cool, turn power back on while monitoring the voltage across the + and - pins of the SSR(s). During normal operation, the voltage should be 5 Vdc, until the water is hot, then drop to below 1 Vdc. The universal power module (UPM) should be replaced if the voltage reads 5 Vdc constantly even though Ready to brew or Over Temp Sensor appears on the display.
3 If the UPM is operating normally, check for a false over-temp error caused by the temperature sensor. Check the resistance across the leads of the temperature sensor. If the resistance is less than 10 k when the water is cool, replace the temperature sensor.

Overview

The G4 control module diagnostics can be used to detect electrical circuit failures in the brewer. When a circuit failure is identified, the individual components and wiring in the circuit must be checked to determine the exact cause of the failure using the ELECTRICAL SCHEMATIC. If a failure is not detected using the diagnostics, troubleshoot the problem according to the symptoms listed in other sections of this TROUBLESHOOTING GUIDE.

The diagnostics can also be used to help diagnose certain mechanical failures. See the following steps.

Using the Diagnostics

1 Enter programming mode by tapping the (white) Curtis logo on the touchscreen five (5) times.
2 Enter the access code, then press OK (the default code is 1 2 3 4).
3 The MAIN MENU screen will appear. Press Control Settings.
4 Press Diagnostics. When prompted, place an empty container under the brew basket, then press OK.
5 Press a button to test the desired circuit or Auto Test to test all circuits. If a button is highlighted green the circuit has passed the (electrical) test. If the button is highlighted red, the circuit has failed the test.

If the circuit tested fails, check to make sure that power is being supplied to the component during normal operation. If power is supplied, and it does not operate, replace the component. If power is not being supplied, check the wiring and the UPM.

If a valve circuit passes the test, check for a mechanical failure by listening for the valve to "click" when the test button is pressed. To check for a failed pump run a brew cycle and check for fluid flow through the pump.
