Problem: Water Will Not Run Into The Sump Trough During The Freeze Cycle

Step 1 Verify water is supplied to the ice machine, and then start a new freeze sequence by moving the ICE/ OFF/CLEAN toggle switch to OFF then back to ICE.

Step 2 Wait until the freeze cycle starts (approximately 45 seconds, the freeze cycle starts when the compressor energizes).

Step 3 Disconnect the water level probe from the water level probe terminal on the control board.

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 disconnecting the water level probe. If you restart the test you must reconnect the water level probe, restart the ice machine, (step 1) and then disconnect the water level probe after the compressor starts.
