Normal operation – Stage 6
When the dwell time of 20 minutes has expired, the B-T LED goes off. The ice machine goes 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). The 20M LED remains on for 20 minutes after an over-torque condition has
occurred. The ice machine remains 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.
