Thermistor
This failure happens when the control can not detect the ATC thermistor.
The ATC is disabled and this failure code is saved on memory. This fault is not displayed to user and the
defaults temperatures for fi lling are:
Tap cold - cold valve only
Cold - cold valve only
Cool - cold and hot valve
Warm - cold and hot valve
Hot - hot valve only
No Speed
• This occurs when there is no motor speed sensor feedback. To test it, put the washer in Drain & Spin and
wait until the motor starts up. If the motor speed sensor is not operating after 3 seconds, the washer will
go to Pause. This error could be caused by the harness, motor speed sensor, or board.
• On this failure, the control will save the failure in memory and continue working.
Lid Lock Not Open/Close
• Lid Lock (Service and Display to user). This failure occurs when the lid can not be locked or unlocked. The
control attempts 5 times to release or lock the lid , if the lid is not released, the control goes to pause
state and will wait 4.25 minutes to try again to release or lock the lid, if the lid continues without release
or lock, the control attempts 1 more time.
• If the lid will still not release or lock, the control goes to failure state.
Lid Switch
• Occurs when the control runs 3 continuous agitation/spin cycles without receiving the lid switch open
signal.
• This Lid switch error will be reset when the control sees a lid switch transition open/close again.
Triac in Short
• The triacs that control the motor windings have failed.
• Main Board must be replaced.
Redundancy Feedback
• This error occurs if the main control detects that the motor controller is not activating the lid lock circuit.
• Main Board must be replaced.
Wash Transistor
• This error occurs if the washer tries to agitate with less than the minimum allowed water level, which
would indicate a failed board.
• Main Board must be replaced.
