Wash motor inoperative — defective connection

From Tech Sheet W10355653, p.25:

1.Disconnect power. Check all wash motor circuit connections with multimeter. Repair/replace open connections/components. See 'Checking loads and fuses with multimeter' section.

2.Measure the drive motor winding resistance at the main control connector. Expected: 2 to 6 ohms between winding pairs.

3.Rotate the drum by hand and check for free rotation. Inspect the belt and pulley for glaze or wear; a slipping belt mimics a motor fault under load.
