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 fl oat 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
2.5 AMPS 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 fl oat reservoir
senses water.
