TROUBLESHOOTING GUIDE

WARNING:
Electric Shock Hazard – the following procedures are to be performed only by a qualified service technician. Disconnect power when replacing components. 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.
Notice: After replacing or emptying the water tank, be sure to run the First Time Power Up Instructions in the Installation Instructions section. Failure to do so may result in damage to the unit.

Troubleshooting Guidelines

• A water boiler that is not level may not function properly. Make sure the unit 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 multimeter 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 fewer 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 unit with the appropriate cover removed to allow access to the valve.
3. Monitor the voltage at the inlet 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, then trace the fault back to the source.

No Power

1. Make sure the circuit breaker to the circuit supplying power to the unit is not tripped and is turned on.
2. On units with a power plug, make sure it is connected to the power receptacle.
3. Make sure that the main power toggle switch (if applicable) 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 create heat. Check chassis ground.

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, wait for the water tank to cool and 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, water filter, or 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 liquid level control board and the inlet valve. Check for corroded connections.
4. f the wiring between the control board 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 probe. If the water tank does not start to fill, replace the control board.

Water Tank Overfills

1. Turn the main power toggle switch OFF (or unplug the power cord). If water continues to flow when the power is turned off, replace the inlet valve.
2. If the water stops flowing to the water tank when power is on and resumes when power is 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 liquid level control board. Also, check the ground connection to the liquid level control board. If all connections are OK, replace the control board.

Water Does Not Heat At All
If the water heats, but is not hot enough, see Water Not Hot Enough.
The following steps are performed with the control box 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 (nominal resistance is 13 Ohms).
2. If there is no power to the element, trace the circuit back (using the ELECTRICAL SCHEMATIC) to the power source(s) to find out where power is lost.

Water Heats More Slowly Than Usual

1. Check for the proper voltage across the terminals of the heating element.
2. If the proper voltage is being supplied, disconnect the heating element and check for high resistance (nominal resistance should be 13 Ohms). Replace a heating element if the resistance is too high.

Water Not Hot Enough

1. Check for the correct temperature setting on the thermostat knob.
2. Make sure that the water has had sufficient time to heat. Heating time for cold water can be up to 60 minutes.
3. If the temperature setting is OK, check the heating elements for high resistance (nominal resistance should be 13 Ohms). Also, make sure all elements are getting power.
4. If the elements are OK, contact the Curtis Technical Support department to determine if temperature adjustments are necessary.

Water Too Hot (Boiling or Excessive Steaming)

1. If operating the urn at higher elevations, contact the Curtis Technical Support department to determine if temperature adjustments are necessary.
2. Check for a thermostat that is stuck closed. Replace as necessary.

Thermostat Adjustment
The thermostat is factory set to cut off at 200ºF. If necessary, adjust it as follows:

1. Turn the main power switch OFF.
2. Rotate the thermostat knob to the right, to the BOIL position.
3. Pull off the knob.
4. In the thermostat stem, locate the tiny adjustment screw.
5. Using a small screwdriver, adjust the temperature up or down. Turning the screw ¼ turn to the left will increase the temperature by about 20°F. Turning the screw ¼ turn to the right will decrease the temperature by 20°F.
6. Replace the knob.
7. To determine the temperature setting, turn the urn power switch ON, insert a thermometer probe into the water after about 60 minutes, and re-adjust as necessary according to the steps above.
