BREW SOLENOID VALVE
FIG. 2 BREW SOLENOID VALVE
Location:
The brew solenoid valve is mounted on the left side
in the bottom rear of the brewer.
Test Procedures:
1. Disconnect the brewer from the power source.
2. Disconnect the white and white/green wires from
the solenoid valve. With the ON/OFF switch in the
"ON" upper position press the start switch.
3. With a voltmeter, check the voltage across the
white and white/green wires. Connect the brewer
to the power source. The indication must be 120
volts ac.
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
Diagram and check brewer wiring harness.
5. Check for continuity across the solenoid valve coil
terminals.
If continuity is present as described, reconnect the
white and white/green wires to the solenoid valve.
If continuity is not present as described, replace the
solenoid valve.
6. Check the solenoid 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 solenoid
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 solenoid valve, there may be a block-
age in the water line before the solenoid 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
solenoid valve.
Removal and Replacement:
1. Remove all wires from solenoid valve.
2. Turn off the water supply to the brewer.
3. Disconnect the water lines to and from the sole-
noid valve.
4. Remove the two hex-head screws holding the
mounting bracket to the brewer base.
5. Securely install the new solenoid valve.
6. Attach the mounting bracket to the brewer base.
7. Securely fasten the water lines to and from the
solenoid valve.
8. Refer to Fig.3 when reconnecting the wires.
