6)Pump-Out Cycle – LEDs 1, 3, and 2 are on (10/20 second pump-out)– The 1st pump-out occurs after the 11th freeze cycle, then every 10th cycle thereafter. Comp and FMRs remain energized. HGVs and X10 relay energize. LLVs de-energize.

PM de‑energizes for 2 seconds, then X11 relay energizes, allowing PM and DV to energize for 10 seconds. PM energized through X11 relay (energized) terminal #4 (BR wire) and terminal #6 (R wire), then through control switch terminal #6 (R wire) and terminal #5 (R wire). DV energized through X10 relay (energized) terminal #5 (V wire) and terminal #3 (Y wire), then through X13 relay (de-energized) terminal #6 (Y wire) and terminal #2 (LBU wire), then through X11 relay (energized) terminal #3 (LBU wire) and terminal #5 (GY wire). This pump-out removes contaminants from the water tank through DV and allows for a power flush of F/S. Diagnosis: PM Operation: If PM does not come on, check CB K1 connector pin #5 (DBU wire) (X11 relay coil voltage) to a neutral (W wire) for 115VAC. If LED 3 is on and 115VAC is not present, replace CB. If 115VAC is present, X11 relay should energize and X11 terminals #4 (BR wire) and #6 (R wire) should be closed. Check X11 relay terminal #6 (R wire) for 115VAC to a neutral (W wire). If 115VAC is not present, check X11 relay coil and contact continuity. If 115VAC is present and PM is still not energized, check control switch continuity between terminal #5 (R wire) and #6 (R wire). If closed, check PM windings and capacitor. DV Operation: If water does not pump out, check CB K1 connector pin #1 (V wire) (power supply for DV operation) and CB K1 connector pin #2 (P wire) (X10 relay coil voltage for DV operation) to a neutral (W wire) for 115VAC. If 115VAC is not present on either circuit, replace CB. If 115VAC is present, X10 relay terminals #1 (Y wire) and #5 (V wire) should be closed. Check X10 relay terminal #3 (Y wire) to a neutral (W wire) for 115VAC. If 115VAC is not present on terminal #3 (Y wire), check X10 relay coil and contact continuity. If 115VAC is present on X10 relay terminal #3 (Y wire), go to X13 relay and check X13 relay terminal #2 (LBU wire) to a neutral (W wire) for 115VAC. If 115VAC is not present, check X13 relay contact continuity between terminal #2 (LBU wire) and terminal #6 (Y wire). If contacts are open, confirm X13 is de-energized. If 115VAC is present, check X11 relay terminal #5 (GY wire) to a neutral (W wire) for 115VAC. If 115VAC is not present, check continuity between X11 relay (energized) terminal #3 (LBU wire) and terminal #5 (GY wire). If 115VAC is present on X11 terminal #5 (GY wire), check continuity on DV coil. Next, remove DV housing and check/clean DV assembly, make sure that the drain line is not clogged.

7)Normal Harvest Cycle – Same as the initial harvest cycle. Return to step 4.

Note: Icemaker continues to cycle until BC is satisfied or power is switched off. The icemaker always restarts at the 1-minute fill cycle.
