This test will check the wiring to the drain motor and the drain
motor itself. The following items are part of the drain motor
circuit.
■ Harness/Connection
■ Drain Motor (Variable Speed)
■ Control Board
Test Procedure
1. Verify that drain hose or drain path is not obstructed.
Check for blockage from sump check valve to customer's
plumbing. Check for plugged garbage disposal or disposal
plug not knocked out. Check drain loop, stuck check valve,
