Location:

The Proximity Sensor and Magnet are located on

the back side of the Auger Motor assembly.

Test Procedures:

1. Ensure the the nut and lockwasher are tightened securely to prevent the Magnet from slipping, which causes a false reading when testing.

2. With a voltmeter, back probe the RED and BLK wires. The indication should be +5VDC.

3. Back probe the BLK and GRN wires. The indication should be an alternating reading of 5-0-5-0VDC. With power ON, the reading will actually ﬂuctuate in the 3VDC range.

If voltage is present as described, the Proximity RPM Sensor is operating properly.

3. Disconnect the dispenser from the power source.

If voltage is present as described, proceed to step 4. If voltage is not present as described, refer to the Wiring Diagrams and check the dispenser wiring harness back to the transformer (See TRANSFORMER).

If voltage is present as described, proceed to step 9. If voltage is not present as described, refer to the Wir- ing Diagrams and check the dispenser wiring harness back to the power cord. Also check for an open ﬂoat switch.

Liquid Level Control Circuitry:

6. Gently pull the liquid level probe out of the tank lid and inspect for corrosion. Replace it if necessary.

7. Place the probe so that neither end is in contact with any metal surface of the dispenser.

8. With a voltmeter, check the voltage across J1 pins 4 and 8 on the control board. Connect the dispenser to the power source. The indication must be:

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 blockage in the tank 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 two 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. Remove the #10-32 screw securing the solenoid valve to side of the tank. 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 schematic wiring diagrams when reconnecting the wires.
