This troubleshooting section 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 some 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. CSM diagnostics are covered in this service guide.

Will Not Start

• Check voltage input to the dishwasher.

• Verify door switch operation, consult 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 refer to Demo Mode 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.

Cure: The CSM (Current Sense Module) is tripped and must be fully diagnosed. Refer to On the

Main Control Board CSM section of this guide.

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.

Diagnosis: The dishwasher may be in Demo Mode.

Cure: To exit Demo Mode, refer to Demo Mode section of this guide.
