CONTROL BOARD ERRORS
The control board monitors the following:
Low water
Gear motor amperage
High pressure
Clogged drain
There are two different errors - Soft errors and hard
errors.
• Soft errors can be reset by cycling power on/off.
• Hard errors can not be cleared by cycling power
on/off and must be reset by pressing the control
board reset button.
LO WATER - WATER LEVEL IS BELOW LOW
WATER SENSOR FOR MORE THAN 120 SECONDS
Soft Error
The control board stops the ice machine, energizes
the Lo Water & Service lights and leaves the water
solenoid energized. When water contacts the low
water probe the ice machine will resume ice making.
Hard Error
The water level sensor has 4 probes and the 2 longest
probes reach to the bottom of the water reservoir.
When no water is sensed on these probes within 60
seconds of power up (or the water level sensor is
disconnected or shorted) the control board stops the
ice machine and energizes the Lo Water light. The ice
machine must be reset by pressing the control board
reset button.
