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 and 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 the water level probe from the
control board, then connect a jumper from the control
board terminal and any cabinet ground, then refer to
chart on next page.
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.
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.
