FIG. 20 SOLENOID VALVE
P2173.80
10179 060100
Location:
The solenoid valve is located in the left rear cor-
ner of the hood.
Test Procedures:
1. Disconnect the brewer from the power source and
remove both wires from the solenoid valve coil
terminals.
2. With a voltmeter, check the voltage across the
white and white/blue wires when the On/Left
switch is in the upper position and the Start switch
is pressed to the lower position and released.
Connect the brewer to the power source. The in-
dication must be 120 volts ac for the approximate
setting on the brew timer dial and then return to
zero.
3. Disconnect the brewer from the power source.
If voltage is present as described, proceed to #4.
If voltage is not present as described, refer to the
Wiring Diagram
and check the brewer wiring harness.
4. Check for continuity across the solenoid valve coil.
If continuity is present as described, reconnect the
white and white/blue wires and proceed to #5.
If continuity is not present as described, replace the
solenoid valve.
5. Check the solenoid valve for coil action. Connect
the brewer to the power source, place the On/Left
switch in the upper position, press and release
the Start switch. Listen carefully in the vicinity of
the solenoid valve for a “clicking” sound as the
coil magnet attracts and after the approximate
setting on the brew timer dial, repels the plunger.
6. 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 or after 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 the solenoid valve coil.
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 #8-32 nuts holding the solenoid
valve mounting bracket to the hood.
5. Lift out the solenoid valve.
6. Remove the solenoid valve from the mounting
bracket.
7. Securely install the new solenoid valve to the
mounting bracket.
8. Attach the mounting bracket to the hood.
9. Securely fasten the water lines to and from the
solenoid valve.
10. Refer to FIG. 21 when reconnecting the wires.
