Self-flushing (when enabled)
At the completion of the 20 minute time delay, the machine checks for a cumulative one hour of ice making time
since the last off-cycle flush . If the cumulative ice making time exceeds one hour, the machine will energize the
drain valve P19 for 60 seconds to drain the evaporator . It will then refill with water, flush again, refill and begin
making ice if the
LOW BIN LED is on . If the ice making time is less than 1 hour, the machine will start and begin
making ice without draining the evaporator .

Diagnostic Stages
High gearmotor amps – Stage 1
The
HI AMPS error and TIME DELAY LEDs are on indicating that the control board has sensed an over-torque
condition at the P4 terminal (more than 3 amps from the gearmotor) or no current draw (0A) and shut the ice
machine down (strike one) . The HI AMPS and TIME DELAY LEDs will remain on for 60 minutes after an over-
torque condition has occurred . The ice machine will remain off as long as these two LEDs are on . After the
60 minute time delay, these LED lights turn off, and the control board will try to go through a normal start-up
sequence .
