door switch contacts and
all connections in the
Door Switch circuit while
opening and closing the
door latch.
- If high resistance with
door closed, check/x
loose connections.
4. Measure resistance of
door switch contacts
while checking
mechanical operation of
latch assembly. Check for
broken plastic pieces on
latch assembly. Replace
latch if faulty.
3. If none of the
above.
1. Unplug dishwasher or
disconnect power.
2. Check for 13 V DC
from P9-5 to P9-6 by
completing the following
steps:
A. Connect voltage
measurement equipment.
