Action
• Fill tub using Service Mode test 7 and
check drain pump operation using
Service Mode test 12.
• Check drain hose for blockages.
• Confirm standpipe height is within
recommended guidelines.
• If pump does not operate, check that
the resistance of the pump matches
resistance table and verify 120 VAC
while pump is operating at J512.
• Check pressure tube for pinches where
it goes through top cover grommet.
• Use pressure sensor test 10 to ensure
correct pressure sensor operation.
• Check pressure tube for trapped water.
• Ensure pressure chamber port is free
from obstruction using drill bit size 1/16-
in. by hand so as not to drill through the
inner wall.
• Check for leaking water valves.
• Use pressure sensor test 10 to ensure
correct pressure sensor operation.
• Consumer education on leaving
sopping wet items in basket for more
than 24 hours.
• Pausing the machine for greater than
24 hours can cause this.
• Can be caused by out-of-balance.
• Can be caused by starting a cycle with
the "no spin" option selected.
• Check the output voltage from the
pressure sensor to ensure it matches
the water level in the basket according
to the pressure sensor chart.
• Check pressure tube for trapped water.
• Ensure pressure chamber port is free
from obstruction using drill bit size 1/16-
in. by hand so as not to drill through the
inner wall.
• Check pressure tube for pinches where
it goes through top cover grommet.
• Check pressure tube for trapped water.
• Check for any leaking water valves.
• Check home water pressure.
• Check the output voltage from the
pressure sensor to ensure it matches
the water level in the basket according
to the pressure sensor chart.
• Check for excessively OOB load.
Customer Education on how to
distribute load.
• Check the basket for excessive friction
or for being excessively out of round.
Basket should spin freely and without
wobble. If friction is found, remove it. If
basket is bad, replace it.
• Check speed sensor for loose
connection to the motor.
