Pulse Brew Guidelines

• Filter pack type coffees typically extract better with the A and B pulse setting.
• Decaffeinated coffees typically extract better with the B pulse setting.
• High-yield coffees typically extract better with the C pulse setting. Of course, any of the A, B or C settings may be used to suit your taste profile.
• Settings D and E are manual pulse counts.

By-Pass – helps control extraction with larger brews. The factory default settings are LARGE 35% (10% for TP1 series), MEDIUM 10%, SMALL Off. It reduces contact time to avoid extraction of undesirable bitter and harsh flavor compounds. The setting range is 0% to 50%. Once accessed, press or ► to choose the desired setting, then, press to exit.
Language Menu – changes the language that appears on the display. The factory default setting is English. This feature is programmable for changing and adding languages. Once accessed, press or ► to choose the desired setting, then press to exit.
Model Select Menu – changes the model number and number of batches (to match the label on the universal control module, the factory default is Gemini-Twin, One batch). Once accessed, press or ► until the model number matching the model number label on the brewer appears, then press . Press or ► until the number of batches matches the number of batch sizes on the UCM label, then press to exit.

TROUBLESHOOTING GUIDE

WARNING:
Electric Shock Hazard – the following procedures are to be performed only by a qualified service technician. Disconnect power when replacing components. Lock out and tag the circuit breaker on units without a power plug. Neither Wilbur Curtis Co., Inc. nor the seller can be held responsible for the interpretation of this information, or any liability in connection with its use.
Scald and Burn Hazard – keep body parts clear of hot surfaces during troubleshooting.
IMPORTANT: If it is necessary to replace the G3 universal control module (UCM), 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 with the appropriate cover removed to allow access to the valve.
3. Run a brew cycle while monitoring the voltage at the valve coil terminals. If voltage is present on the terminals, you should hear the valve click open/closed at the moment power is applied or removed from the terminals. The inlet valve should open any time the water tank is not full. If the valve does not open, replace the valve. If voltage is not detected, first check the wiring. If the wiring is OK, replace the UCM.

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. Loose connections can create heat. Check chassis ground.
5. Check to make sure power and ground are being supplied to the control module (UCM). If there is power into UCM, but display is blank, 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 control module (UCM) and the valves.
2. If Brewing does not appear on the display, check for a faulty universal control module (UCM).

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 control module (UCM). 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 UCM. Afterward, if the error message comes back after resetting the control and power modules, replace the UCM.

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 stops 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 control module (UCM). If both are OK, replace the UCM.

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 clogged water supply line, water filter 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 control module (UCM) and the inlet valve. Check for corroded connections.
4. If the wiring between the UCM 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 UCM.

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 UCM. If the wiring is OK, replace the UCM.

*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 control module (UCM).

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 control module (UCM). Run a brew cycle and check for power from the UCM to the dump (brew), bypass and dilution valves. If there is no power output, replace the UCM. *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 or 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 water filter is not clogged.
2. 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.
3. Check for blockage at the inlet valve inlet and outlet and that it opens completely. Check for blockage in the tubing between the inlet valve and the water tank.
4. Check the water probe wire for an open condition or corroded connections.
5. 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.
6. Check for power from the universal control module (UCM) to the inlet valve. If the wiring is OK, replace the UCM.

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 control module (UCM).

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 cut, 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 UCM, but Heating… appears on the display, check the wiring from the UCM to the SSR(s). If the wiring is OK, replace the UCM.

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 above 4000 feet.

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 sensor 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 control module (UCM) constantly has +5 Vdc output (nominal) to the solid state relay (SSR), regardless of the resistance of the temperature sensor. If so, the UCM is probably bad.
4. If the UCM 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 UCM 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 UCM 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 UCM 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.
