SOLENOID VALVE
FIG. 28 SOLENOID VALVE
Location:
The solenoid valve is located inside the hood on
the right side of the upper component bracket.
Test Procedure:
1. Disconnect the brewer from the power source.
2. Remove both wires from the solenoid valve coil
terminals.
3. With a voltmeter, check the voltage across the
removed wires:
a.) White and violet wires on 120, 120/208 and
120/240 volt brewers.
b.) Red and violet wires on 200, 230 or 240 volt
brewers.
Connect the brewer to the power source. The
indication must be:
c.) 120 volts ac for two wire 120 volt models, three
wire 120/208 volt models and three wire 120/240
volt models.
d.) 200 to 240 volts ac for two wire 200, 240 or 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 the
Wiring Diagrams
and check brewer wiring harness
terminals.
5. Check for continuity across the solenoid valve coil
terminals.

If continuity is present as described, reconnect the
white and violet wires on 120, 120/208 and 120/240
volt brewers, red and violet wires on 200, 230 or 240
volt brewers.
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. Listen carefully in
the vicinity of the solenoid valve for a "clicking"
sound after approximately 1 second, 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
blockage 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 #10-32 slotted head screws and
lockwashers holding the solenoid valve to the
upper component bracket.
5. Lift out the solenoid valve.
6. Securely install the new solenoid valve to the
upper component bracket.
7. Securely fasten the water lines to and from the
solenoid valve.
8. Refer to Fig. 29 when reconnecting the wires.
