https://appliancetechmanuals.com
This is an overview of diagnostic capabilities of the electronic control. The control features also allow
retrieval of fault codes when Consumer Error Mode is initiated; operation of loads is achieved in
Service Mode.
Details on Consumer Error Mode and Service
Mode, as well as Service LED are located in the
Electronic Controls section of this service guide.

Flashing Lights

If the control beeps and LED's flash, this indicates the dishwasher door may be in the open position.
If the user interface (UI) is flashing all the LED's or the display (some models) is flashing, this is an
indication of a tripped CSM and the dishwasher is non-responsive, all the LED's will flash until the CSM
is reset. See CSM Diagnostics under CSM (Current Sense Module) under Electronic Controls.

Will Not Start

• Check voltage input to the dishwasher.
• Verify door switch operation, see Consumer Error Mode, in the Electronic Controls section of
this service guide.
• Door must be closed within 5 seconds of pressing Start Pad (Safety Feature).
• Check the main board Service LED (see Main Control Diagnostics in Electronic Controls).
• Verify that the dishwasher is not in Demo Mode. Please see Demo Mode under Electronic
Controls section of this guide.
• CSM (Current Sense Module) tripped. Please refer to On the Main Control Board CSM in the
Electronic Controls section of this guide.
Symptom: If the dishwasher is "dead", no LED operation, no button operation or beeping occurs.
Diagnosis: Attempt placing the dishwasher in Consumer Error Mode.
Solution: The CSM (Current Sense Module) is tripped and must be fully diagnosed. Refer to On

Symptom: If the start button either does not respond or it makes a triple beep sound every time it's
pressed AND all other buttons respond as normal.
