REFILL VALVE
Location:
The refill valve is located inside the trunk on the
lower center part of the component bracket.
Test Procedures:
1. Disconnect the brewer from the power source.
2. Disconnect the white and white/blue wires from
the refill valve. Set the "ON/OFF" switch in the "ON"
upper position.
3. With a voltmeter, check the voltage across the coil
wires. Connect the brewer to the power source.
The indication must be 120 volts ac for two wire
120 volt models and three wire 120/208 and 120/
240 volt models.
4. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #5.
If voltage is not present as described, refer to Wiring
Diagrams and check brewer wiring harness.
5. Check for continuity across the refill valve coil
terminals.
If continuity is present as described, reconnect the
white and white/blue wires from the circuit board.
If continuity is not present as described, replace the
refill valve.
6. Check the refill valve for coil action. Connect the
brewer to the power source. With "ON/OFF" switch
in the "ON' upper position press start switch and
listen carefully in the vicinity of the refill valve for
a" clicking" sound as the coil magnet attracts.
7. Disconnect the brewer from the power source.
If the sound is heard as described and water will not
pass through the refill valve, there may be a blockage
in the water line before the refill valve or, the solenoid
valve may require inspection for wear, and removal of
waterborne particles.
If the sound is not heard as described, replace the refill
valve.
Removal and Replacement:
1. Remove both wires from the refill valve.
2. Turn off the water supply to the brewer and drain
the tank.
3. Disconnect the water lines to and from the refill
valve.
4. Remove the two 1/4"-20 screws securing the refill
valve mounting bracket to the component bracket.
Remove bracket and valve as an assembly.
5. Using two 1/4"-20 screws install the new refill
valve and bracket to the component bracket.
6. Securely fasten the water lines to and from the
valve.
7. Refer to FIG. 12 when reconnecting the wires.
8. Install access panels and covers and refer to Initial
Set-up for refill and operation.
