Foreign object such as coin, pin, or clip is
From Service Manual 375006, p.18:
1.Remove the coin or foreign object stuck between the washer vane with pliers.
2.Measure door lock assembly resistance across the PTC terminals. Expected: ~200 ohms cold, rising sharply once energized.
3.Inspect strike and latch alignment. A warped door or misaligned strike prevents the switch stack from closing in the correct sequence.
