SOLENOID VALVE (INLET) (cont.)
fully in the vicinity of the solenoid valve for a "clicking" 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 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.
3.Disconnect the water lines to and from the sole- noid valve.
4.Loosen the two
5.Remove the two
6.Install the two
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 solenoid valve.

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.
