Liquid Level Control Test Procedure
1.Disconnect the dispenser from the power source.
2.Check the voltage across terminals 3 & 4 of the electronic control board with a voltmeter. Connect the dispenser to the power source. The indication must be:
a.) 100 to 120 volts ac for 100 to 120 volt models or
b.) 200 to 240 volts ac for 200 to 240 volt models or
c.) 230 volts ac for 230 volt models.
3.Disconnect the dispenser from the power source. If voltage was present as described, proceed to #4. If voltage was not present as described, refer to the Wiring Diagrams and check the dispenser wiring harness.

4.Remove the pink wire from terminal 5 of the elec- tronic control assembly.
5.Check the voltage across terminals 1 & 4 of the electronic control board with a voltmeter. Connect the dispenser to the power source. The indication must be:
a.) 100 to 120 volts ac for 100 to 120 voltmodels or
b.) 200 to 240 volts ac for 200 to 240 volt models or
c.) 230 volts ac for 230 volt models after a delay of approximately 5 seconds.
6.Disconnect the dispenser from the power source.
If voltage was present as described, the liquid level con- trol of the system is operating properly, proceed to #7. If voltage was not present as described, replace the electronic control board and the temperature sensor in the tank lid.
