Drain check - pump motor impeller damaged
From Service Manual 286334, p.26:
1.Check if there is any alien substance inside the draining pump motor; check drain pump resistance (approximately 8 ohms).
2.Measure drain pump winding resistance at connector J7 on the main control. Expected: 12 to 16 ohms at room temperature.
3.Back-probe the pump driver output under load. Verify the board switches the pump at 120 VAC during the drain portion of the cycle.
