Normal operation – Stage 6
When the dwell time of 20 minutes has expired, the B-T LED goes off. The ice machine will go through the normal
start-up sequence when the bin level control signals the control board for ice. The WTR LED will remain on as long as
the water sensor in the float reservoir senses water.

Diagnostic sequence – Stage 7
The 20 minute error LED (20M) is on indicating that the control board has sensed an over-torque condition (above 3A
on the gearmotor) and shut the ice machine down. The 20M LED will remain on for 20 minutes after an over-torque
condition has occurred. The ice machine will remain off as long as the 20M LED is on. When the 20M LED goes off,
the control board will try to go through a normal start-up sequence. The WTR LED remains on as long as the water
sensor in the float reservoir senses water.
