DIAGNOSING WATER LEVEL CONTROL CIRCUITRY
Problem: Water Trough Overfilling During The
Freeze Cycle
Step 1 Start a new freeze sequence by moving the ICE/
OFF/CLEAN toggle switch to OFF, then back to ICE. (if
water flows with the switch off, check the water inlet
valve).
Step 2 Wait until the freeze cycle starts
(the freeze cycle starts when the water pump energizes).
Step 3 Disconnect water level probe wire from control
board and connect a jumper from the control board
terminal and any cabinet ground, then refer to chart.
Step 3
Important
This restart must be done prior to performing
diagnostic procedures. This assures the ice
machine is not in a freeze cycle water inlet valve
safety shut off mode. You must complete the entire
diagnostic procedure within 6 minutes of starting.
Important
For the test to work properly you must wait until the
freeze cycle starts, prior to connecting the jumper
wire. If you restart the test you must disconnect the
jumper wire, restart the ice machine, (step 1) and
then reinstall the jumper wire after the compressor
starts.
