SOLENOID VALVES (DISPENSE)
FIG. 27 DISPENSE SOLENOID VALVES
P1203.45
Location:
The dispense solenoids are located on the
upper right side of the tank.
Test Procedures:
1. Disconnect the dispenser from the power source.
2. Disconnect the white and white/violet, white/blue
or white/ brown 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, white/blue or white/brown wires with a
voltmeter. Connect the dispenser to the power
source. The indication must be 120 volts ac for
two wire 120 volt models, three wire 120/208,
120/240 volt models and 240 volts ac for two
wire 240 volt models.
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, white/blue or white/brown
wires to the solenoid.
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 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, white/blue or
white/ brown wires from the solenoid valve.
2. Turn-off the water supply to the dispenser.
