Description
Control received an extended period of
pressure readings that is nearing over-flow
levels. Pressure 17.5".
Voltage Output must be present. Could mean
water did get that high due to briefly stuck
water valve. Voltage output of sensor too high
for actual water level because of sensor or
water in pressure tube increasing pressure.
Main micro received and extended period
of pressure readings that is greater than
maximum allowable fill volume. Pressure
16.5". Voltage output must be present. Could
mean water did get that high due to briefly
stuck water valve. Voltage output of Sensor
too high for actual water level because of
sensor or water in pressure tube increasing
pressure.
of a difference in the pressure sensor reading
and the expected pressure sensor reading for
the amount of water the control calculated it
has put in. It assumes there is a pressure leak,
a clog in the pressure hose/system delaying
the increase in pressure, or a significant
amount water leaking out.
Start attempted for a 4th cycle when the
previous 3 cycles have completed with
backup micro seeing lid open. Could mean
the switches didn't occur or backup processor
didn't get the signal because of lack of
connection. See Fault #2 as well.
Signal feedback state from the mode shifter
(agitate or spin) and the state requested by
the control are not the same and the basket
or agitator is rotating faster than 3-4 RPM.
Agitate mode feedback signal is no voltage.

Repair Action
• 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 the output voltage from
the pressure sensor to ensure
it matches the water level in
the basket according to the
pressure sensor chart. If it does
not, the control will need to be
replaced as the pressure sensor
is mounted directly to the control.
• This can happen if a large wet
load is placed in the washer.
• 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 the output voltage from
the pressure sensor to ensure it
matches the water level in the
basket according to the pressure
sensor chart.
• Check house water supply vales
are turned on.
• Check pressure tube for pinches
where it goes through top cover
grommet.
• Check pressure tube for trapped
water.
• Check water valve operation
• Check the output voltage from
the pressure sensor to ensure it
matches the water level in the
basket according to the pressure
sensor chart.
• Open and close the lid to clear
the fault.
• Check harness and connectors
that go to the lid switch.
• If the fault will not clear, replace
the lid switch.
• Check mode shifter coupler for
damage and the ability to slide in
and out freely.
• Use ohm meter to ensure
harness shows continuity to the
mode shifter from the control.
• Check resistance of mode shifter
motor (approximately 5.7K ohms).
• Check for 120 VAC to the mode
shifter motor at the control J512
connector.
• If voltage is present and no
operation, replace the mode
shifter.
