REFILL CIRCUIT

 

 

PROBLEM

 

PROBABLE CAUSE

Will not fill or refill

1.

Power off to brewer

 

 

2.

Water shut off

 

 

3.

Display flashing

4. ON/OFF Switch

5. Lime build up on Probe

6. Refill Valve or Control Board

7. Water is too conductive for proper operation when using the factory setting of sensing thresh- old.

REMEDY

Press warmer switches on control panel to determine if power is ON.

Make sure water is ON.

Brewer has shut down due to malfunction (See Diagnostic Chart in manual, Page 21, or under top lid of brewer).

Make sure ON/OFF Switch is "ON" and indicator is lit.

Remove the Probe and check for lime deposit on tip. Clean and reinstall.

Disconnect the brewer from the power source and remove wires from refill valve coil. Check for continuity across the terminals of the solenoid coil. If continuity is not present, replace the refill valve (See page 29). If continuity is present, the coil may be stuck closed. Shut water off to brewer. Set the ON/OFF switch to the "OFF" position. Open the faucet and drain water down in the tank until flow stops or slows to a trickle. Attach a voltmeter to the terminals of the refill solenoid. Connect the brewer to the power source. Press the switch "ON". Within five seconds, voltage should be present at the solenoid terminals. If voltage is not present, refer to the wiring diagrams and check the wiring harness.
