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 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 the white and violet wires from the so-
lenoid valve.
2. Turn-off the water supply to the dispenser.
3. Disconnect the water lines to and from the sole-
noid valve.
4. Loosen the two #8-32 screws securing the sole-
noid to the rear dispenser housing. Remove so-
lenoid.
5. Remove the two #8-32 U-Type fasteners from the
solenoid bracket.
6. Install the two #8-32 U-Type fasteners and the
two #8-32 screws on the new solenoid.
5. Install new solenoid valve on rear of dispenser
housing and tighten the two screws.
6. Securely fasten the water lines to and from the

Location:
The tank heater is located inside the tank and
secured to the tank lid.
Test Procedure:
1. Disconnect the dispenser from the power source.
2. Check the voltage across the black and white wires
120 volt or 240 volt models or black and red wires
for 120/208 volt models or 120/240 volt models
with a voltmeter. Connect the dispenser to the
power source. The indication must be:
a) 120 volts ac for two wire 120 volt models;
b) 208 volts ac for three wire 120/208 volt models.
c) 240 volts ac for three wire 120/240 volt models
and two wire 240 volt models.
3. Disconnect the dispenser from the power source.
If voltage is present as described, proceed to #4.
If voltage is not present as described, refer to the
dispenser wiring diagram and check the wiring har-
ness.
4. Disconnect the black wire and the white or red
wire from the tank heater terminals.
