7. Ice machine is making ice.
Excessive water in bin or
coming into bin from transport
tube.
1. Failed water sensors. Processor
assumes there is no water when
there is water.
2. Blocked reservoir vent.
3. Defective water feed solenoid
valve. Stuck in open position.
1. Clean or replace water probe
assembly. Check wiring
connections.
2. Clean or replace vent tubes.
3. Replace water feed solenoid
valve.
8. Ice machine is not making ice.
Low Water.
1. Water supply is insufficient.
2. Low water pressure.
3. Defective water feed solenoid
valve. Stuck in closed position.
4. No water feed output from
PC board.
5. Plugged screen on inlet side of ll
solenoid.
6. Plugged check valve.
1. Restore water supply and check

level.
3. Replace water feed solenoid valve.
4. Replace PC board.
5. Remove and clean screen.
6. Remove and clean.
9. Blinking Low Water, power, time
delay.
Machine did not see water
consumption while trying to make
ice.
1. Lack of refrigeration/low
refrigerant charge/leak.
2. Debris shorting reservoir probes.
1. Verify refrigerant pressures,
compressor running, sight glass
clear.
2. Clean probes and reservoir of
debris.
