TROUBLESHOOTING
SERVICE SHOULD BE PERFORMED BY QUALIFIED SERVICE PERSONNEL ONLY.
WARNING: Turn off the "Power/Off/Fill" switch, unplug the power supply cord and allow the coffee brewer to cool before servicing unless electrical testing is required.
WARNING: Make sure installation instructions have been followed before attempting to test this coffee brewer.
This appliance is equipped with an automatic temperature limit control designed to turn the appliance off if it overheats. In that event, do not reset until a qualified service
representative has inspected and repaired the appliance. UNDER NO CIRCUMSTANCE SHOULD THE TEMPERATURE LIMIT CONTROL BE BYPASSED OR AN
ALTERNATE CONTROL USED, AS A FIRE RISK COULD RESULT. IN THE EVENT OF FAILURE, THE HI-LIMIT THERMOSTAT SHOULD BE REPLACED. USE ONLY
ORIGINAL OR AUTHORIZED REPLACEMENT PARTS.
Symptom Remedies
1. The coffee brewer will not operate. The
light does not work and the coffee
brewer will not brew coffee.
Make sure the power supply cord is connected to an appropriate working wall receptacle.
Test the wall receptacle and the circuit breaker in the building.
Make sure the “Power-Off-Fill” switch has been turned on.
Reset or replace the hi-limit thermostat.
Test the “Power-Off-Fill “ Switch. Replace it if necessary.
Test the power supply cord. Replace it if necessary.
Check to make sure the internal wiring is correct. Inspect for loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
2. The coffee brewer will not brew coffee.
The light works.
Test the “Power-Off-Fill “ Switch. Replace it if necessary.
Inspect, clean or replace the flow washer and screen.
Test the thermostat. Replace it if necessary.
Test the tank heating element. Replace the tank if necessary.
Check to make sure the internal wiring is correct. Inspect for loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
If present, check any in-line water filters; check valve or shut-off valves for proper operation or blockage.
3. The coffee brewer will not heat. The
brewing cycle works but the water is
cold.
Test the thermostat. Replace it if necessary.
Check to make sure the internal wiring is correct. Inspect for loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
4. The brewing cycle does not start. The unit
heats or steams.
Test the thermostat. Replace it if necessary.
Inspect, clean or replace the flow washer and screen.
Test the “Power-Off-Fill “ Switch. Replace it if necessary.
Test the solenoid valve. Replace it if necessary.
If present, check any in-line water filters; check valve or shut-off valves for proper operation or blockage.
Check to make sure the internal wiring is correct. Inspect for loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
5. The hi-limit thermostat keeps activating. Test the hi-limit thermostat. Replace it if necessary
Check the hi-limit mounting nuts. The hi-limit should be just snug against the tank. Too much pressure against the tank could
cause the hi-limit to activate prematurely.
Test the brewing temperature. Adjust the thermostat if necessary. (See page 8)
Inspect the wiring on the hi-limit thermostat for loose, damaged or overheating wires or terminals. Repair or replace wiring as
necessary.
WARNING
Under no circumstance should the hi-limit thermostat be by-passed. In the event of failure, the hi-limit thermostat should
be replaced. Use only original or authorized replacement parts.
6. The coffee brewer trips the buildings
circuit breaker.
Too many appliances are connected on one electrical circuit.
The electrical circuits amperage rating is too low. Locate a correctly rated circuit or call an electrician to correct this problem.
This coffee brewer may require a dedicated wall circuit. Check the electrical specifications.
Check to make sure the internal wiring is correct. Inspect for loose, damaged or overheating wires or terminals. Repair or
replace wiring as necessary.
Inspect the tank heating element. Replace the tank if necessary.
7. The beverage level is consistently high or
consistently low.
Inspect and clean the spray head, silicone tubing and fittings.
Test the timer. Replace it if necessary.
Inspect, clean or replace the flow washer and screen.
Test the incoming water supply pressure. Water pressure should be between 30 and 80 psi. If the water pressure exceeds 80
psi, install a water pressure regulator and reduce the water pressure to 50 psi.
If installed, adjust the timer bracket stop plate to increase or decrease the brew volume. See the installation instructions for
correct adjusting procedures on page 7.
