Part Number 000007661 Rev02 02/20 

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.
