Slide shutter fault — no signal change at

From Service Manual 147550, p.42:

1.Check if water is alternating between upper/lower and middle spray arms; check position switch B3/12 at ST14 for low DC pulses at 30 sec intervals.

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.
