Fault
Code
Fault Name Description Repair Action
10 Mode Shift Feedback
Monitor
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.
 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.
11 Clock Monitor 1. AC power line frequency is not 60Hz.
2. Software failure.
1. Check the frequency of the AC
power outlet. If it is more than a
IHZ+]RႇRI+]QRWLI\XWLOLW\
company.
2. If house frequency is good,
update software.
12 Redundant Flood

stuck water valve. Voltage output of Sensor
too high for actual water level because of
Sensor or water in Pressure tube increasing
pressure.
 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.
13 Redundant Lid
Unlocked
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 - 5 RPM
when the lid lock feedback has no voltage
(Lid Unlocked).
Lid Switch Feedback has no Voltage
when the BRPM is > 4 - 5 RPM.
 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.
14 Lid Lock Fault 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.
 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.
15 Water Temp Sensor
Invalid
1. Thermistor disconnected/not present.
2. Failed thermistor
 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.
