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.
3. Drain enough water from the tank (approximately

1.0 gallon) so the water level is below the dispense
valve mounting hole.

4. Disconnect the water line from the solenoid valve.
5. Loosen the  #10-32 screw securing the solenoid

valve to side of the tank. Twist the solenoid valve
clockwise and remove solenoid valve.

6. Using the  #10-32 screw install new solenoid valve

on side of the tank

7. Push the water line onto the tube on bottom of

solenoid valve.

8. Refer to Fig. 32 when reconnecting the wires.

Location:

The hot water solenoid valve is located on the

left side of the tank.

SOLENOID VALVE

Test Procedures:
1. Disconnect the dispenser from the power source.
2. With a voltmeter check the voltage across the

white and blue wires at the solenoid valve. Connect
the dispenser to the power source. The indication
must be:
a) 120 volts ac for two wire 120 volt models
b) 120 volts for three wire 120/208 or 120/240 volt
models
c) 240 volts ac for two wire 240 volt models.
d) 230 volts ac for two wire 230 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
wiring diagram and check dispenser wiring harness.

4. Disconnect the white and blue wires from the

solenoid valve.

5. Check for continuity across the solenoid valve coil

terminals.

If continuity is present as described, reconnect the
white and blue wires to the solenoid.
If continuity is not present as described, replace the
solenoid valve.
