DIAGNOSING FREEZE CYCLE POTABLE 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.
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
with-in 6 minutes of starting
.
Step 2
Wait until the freeze cycle starts
(approximately 45 seconds, the freeze cycle starts when the water
pump energizes) then connect a jumper from the water level probe to any cabinet ground.
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 water pump starts.
