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, & refer to
chart on the next page
.
This rest art must be d one p rior to performing
diagnostic procedures. This assures the ice machine
is not in a Freeze cycle water inlet valve safety shut-
off mode. Y ou must comple te the entire dia gnostic
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 le vel pro be, rest art the ice
machine (step 1), and th en d isconnect the water
level probe after the compressor starts.
