Pumping time exceeded – damaged pump, wire
From Service Manual 682825, p.37:
1.Check pump, check wire harness, check hose.
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.
