Ice machine disposition Possible causes Corrective action
FLASHINGON or OFF
Legend:
OFFON
6. 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.
7. Ice machine is not making ice.
Lo 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
water lters. If evaporator was
completely empty the reset
button may have to be pressed
to restart the ice machine.
2. Ice machine will eventually start
when water reaches normal lo
level.
3. Replace water feed solenoid
valve.
4. Replace PC board.
5. Remove and clean screen.
6. Remove and clean.
8. Blinking Lo water, power, time
delay.
1. Scale is shorting probes.
2. Water quality is such that the
ice is not forming on the wall of
the evaporator causing 'uff' ice.
This causes a water restriction at
the bushing housing not allowing
water into the reservoir.
1. Clean probes.
2. Test water and address water
quality.
ATTENTION!
To prevent circuit breaker overload, wait 5 minutes before restarting
this unit. This allows the compressor to equalize and the evaporator
to thaw.
