SOLENOID VALVES (DISPENSE)
FIG. 30 DISPENSE SOLENOID VALVES
P1637.40
Location:
The dispense solenoids are located on the up-
per left side of the tank.
Test Procedures:
1. Disconnect the dispenser from the power source.
2. Disconnect the white and white/violet, orange or
tan wires from the solenoid valve. With the “RUN/
RINSE” switch in the "RINSE" upper position
press the appropriate dispense switch on front of
the door.
3. Check the voltage across the white and white/
violet, orange or tan wires with a voltmeter.
Connect the dispenser to the power source. The
indication must be 120 volts ac.
4. Disconnect the dispenser 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 dispenser wiring harness.
5. Check for continuity across the solenoid valve
coil terminals.
If continuity is present as described, reconnect the
white and white/violet, orange or tan wires to the so-
lenoid.
If continuity is not present as described, replace the
solenoid valve.
6. Check the solenoid valve for coil action. Connect
the dispenser to the power source. With "RUN/
RINSE" switch in the "RINSE" upper position press
the appropriate dispense switch and listen care-
fully in the vicinity of the solenoid valve for a "click-
ing" sound as the coil magnet attracts.
7. Disconnect the dispenser 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 tank water outlet 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 the white and white/violet,orange or tan
wires from the solenoid valve.
2. Turn-off the water supply to the dispenser.
10. Refer to Fig. 29 when reconnecting the wires.
