Normal operation – Stage 6
When the dwell time of 20 minutes has expired, the B-T LED goes off. The icemaker 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 2.5 AMPS on the gearmotor). The 20M LED remains on for 20 minutes after an over-torque condition has
occurred. The icemaker 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.
