TROUBLESHOOTING

Read and follow the cautions below before attempting to service this coffee brewer.

CAUTION:

Read and verify that the installation instructions have been followed before attempting to operate this appliance.

Incorrect installation or operating procedures will void the warranty and may damage this appliance.

Unplug the power cord before servicing, unless electrical testing is required. Be certain the power supply is of

the correct rating and polarity before connecting the power supply cord. The chassis must be grounded to

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 or circuit breaker. 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 warmer elements for damage. Replace it if necessary.

Inspect the immersion element for damage. Replace it if necessary.

7. The brewing temperature is

either too hot or too cold.

Make sure that the thermostat sensor is inserted all of the way into the well.

Adjust or replace the thermostat. Turn the adjustment screw clockwise to

increase the temperature, counter-clockwise to decrease. Turn the adjustment

screw a maximum of 1/8 turn per adjustment. Retest and adjust again if

necessary. The recommended temperature is between 192°and 196°F. Test

below the brew cone with water only.

WARNING:

If the thermostat cannot be adjusted properly it should be replaced. The

thermostat is calibrated at the factory and no attempt should be made to

recalibrate it. Use only original or authorized replacement parts.

Test the thermostat sensor with an ohm meter. The sensor should read

approximately 100,000 Ωat a normal room temperature of approximately 25c.

As the heat to the sensor increases, the reading should decrease to zero.

Note: The thermostat sensor must be coated with a thermal mastic heat transfer

compound. (KMP Catalog Number PM8 or equivalent.)

Inspect the inside of the tank for excessive hard water deposits on the thermostat

well. Clean the well if necessary.

Symptoms Solutions

8. The brewing cycle is too slow. Inspect and clean the spray head, silicone tubing and siphon fittings.

Do not over tighten the tank lid hold-down screw. (See #10.)

9. The beverage level is

consistently high or

consistently low. (Automatic

models only.)

Adjust the timer. To increase the beverage level turn the timer adjustment knob

clockwise. To decrease the beverage level turn the adjustment knob

counterclockwise. Turn the adjustment knob 1/2 reference mark maximum per

adjustment. Retest and adjust again if necessary. Note: The marks on the timer

are for reference only and are not intended as an accurate measurement of time.

Test the timer. Replace it if necessary.

Open the flow control and clean the flow control washer and flow control screen.

The flow control washer should be .25 gpm. Incorrect flow washers can cause

inaccurate beverage levels. The code printed on the back of the flow washer

should be “CCP”.

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.

10. The beverage level is

inconsistent.

Inspect and clean the spray head, silicone tubing and siphon fittings.

Inspect the reservoir and reservoir tubing for blockage.

Make sure the tank cover is in place correctly and that the gaskets are in good

condition.

Do not over tighten the tank lid hold-down screw. (See page 18, Item #16.) The

screw should be just tight enough to seal the tank. Over tightening the screw can

deform the tank lid causing water leaks and can also change the angle of the

siphon fitting causing inconsistent brew levels

Water or condensation on the timer may cause it to malfunction. Dry the timer

and retest. (Automatic models only.)

Test the incoming water supply for inconsistent water pressure. If the water

pressure is inconsistent, install a water pressure regulator and reduce the water

pressure to minimize water pressure fluctuations. (Automatic models only.)

Test the timer. Replace it if necessary. (Automatic models only.)

If present, check any in-line water filters, check valves or shut-off valves for

proper operation or blockage. (Automatic models only.)
