DISPENSE SOLENOID VALVE
P1935
FIG. 31 DISPENSE SOLENOID VALVE Location:
The dispense solenoid valve is located on the left side of the dispenser base inside of the rear cover.
Test Procedures:
1.Disconnect the dispenser from the power source.
2.Disconnect the white/red and white/brown wires from the solenoid valve.
3.Check the voltage across the white/red and white/ brown wires with a voltmeter. Connect the dis- penser to the power source. The indication must be:
a)120 volts ac for 120 volt models.
b)230 volts ac for 230 volt CE 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 diagrams and check the dispenser wiring harness.
5.Check for continuity across the solenoid valve coil terminals.
If continuity is present as described, reconnect the white/red and 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. Press the dis- pense switch and listen carefully for a "clicking" sound as the 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 the removal of waterborne particles.
If the sound is not heard as described, replace the solenoid valve.
Removal and Replacement:
1.Disconnect the dispenser from the power source and the water supply.
2.Remove the six
3.Remove the white/red and white/brown wires from the solenoid valve.
4.Disconnect the water lines to and from the solenoid valve.
5.Remove the two
6.Remove the two
7.Install a new solenoid valve to the bracket using two
8.Install the solenoid and bracket to the base and secure with two
9.Install the water lines to and from the solenoid valve using pipe thread sealant (BOM #M2526.0000) and tighten securely.
10.Refer to Fig. 32 when reconnecting the wires.
