Description
1. AC power line frequency is not 60Hz.
2. Software failure.
Backup Processor received an extended
period of pressure readings that is nearing
Voltage Output must be present. Could mean
water valve. Voltage output of Sensor too high
for actual water level because of Sensor or
water in Pressure tube increasing pressure.
In spin mode, the lid switch feedback
has voltage (lid closed), for more than
5 seconds the motor speed feedback
assumes the basket is spinning > 4-5RPM
when the lid lock feedback has no voltage
(Lid Unlocked).
Lid Switch Feedback has no Voltage when
the BRPM is > 4-5RPM.
Signal received by control is indicating the
lock will not lock or unlock when requested
or the lid switch is indicating open when the
signal received indicated locked.
1. Thermistor disconnected/not present.
2. Failed thermistor
The total number of times during machine
life the actual amount of time the pressure
sensor indicated the wash water had drained
to empty exceeded the calculated time by the
software.

Repair Action
1. Check the frequency of the AC
power outlet. If it is more than a
company.
2. If house frequency is good,
update software.
• Check pressure tube for trapped
water.
• Check Each Valves Operation...
(Replace Water Valve and send
back to GE)
• 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 lid switch continuity at
J513 on the control.
• Check continuity of lid lock
position. Opened or Closed.
• Check for proper operation of lid
lock. 120VAC while activating
• Check lid lock wiring harness
from the control to lock
assembly.
• Verify that the lid lock is not
blocked by any external debris.
• Check lid switch continuity at
J513 on the control.
• Check continuity of lid lock
position. Opened or Closed.
• Check for proper operation of lid
lock. 120 VAC while activating
• Check lid lock wiring harness
from the control to lock
assembly.
• If lid lock assembly and harness
are OK, update the software.
• Check thermistor resistance
from connector J701 on the
control board. Validate the
resistance matches the table in
mini-manual.
• Check wiring harness and
connections.
• Replace thermistor.
• This fault is set when adaptive
drain cycle occurs to try to
remove the rest of water in tub..
• If the adaptive drain cycle times
out, the control will run a Drain
Pump Clearing algorithm to free
the pump impeller of debris.
clearing algorithm fails look for
fault 18.
• If fault 16 is 100 and fault
18 never occurs there is no
problem...If fault 16 and fault 18
equal each other in faults, then
look for drain blockages including
house standpipe.
