Repair Action
Check the resistance of the lid
lock assembly.
Check the harness for open
wires and or connectors from
the board to the lock assembly.
If lock assembly and harness
prove good at the time of
service, replace the lid lock
assembly.
Replace control if this fault
happens repeatedly.
Physically check the washer
for anything preventing motor
movement.
Check harness and harness
connectors from the control to
the motor.
Verify hall sensor is connected
to the main harness. Put
washer in Service Mode and
run TEST 14, Spin Test. If hall
sensor is bad or disconnected,
the basket will start to spin
normally and then stop spinning
after approximately 5 seconds.
Ensure hall sensor is properly
connected and positioned on
the motor. If basket spins for
approximately 15 seconds, the
hall sensor is most likely NOT
the cause.
TCO should reset in
approximately 45 minutes. If
TCO is tripped, make sure
motor moves freely and that
nothing is jamming it. Replace
motor if it does not.
Check for loose connections at
the control. Reconnect if any
are loose.
Check for recommended house
line voltage to the washer.
