Step 1 Move the 'OFF/ICE/WASH' switch to the 'OFF'
position to turn the machine off.
Step 2 If water continues to flow with the ice machine
off, disconnect power. If water continues to flow with
power disconnected verify water pressure is below 80
psig before replacing the water inlet valve. If the water
stops continue with next step.
Step 3 Check water level sensor mounting and verify
secure wiring connections at the sensor and control
board.
WATER TROUGH NOT FILLING DURING THE FREEZE
CYCLE
Step 1 Verify that the water supply is on and the
water pressure is not below 20 psig.
Step 2 Verify that the correct voltage is supplied to
the machine.

inlet valve.
Step 4 If the water supply and power both check out,
and no water is exiting the valve, continue to step 5
