This troubleshooting section is an overview of the diagnostic capabilities of the electronic control. The control

features allow retrieval of error codes, operation of loads in service mode and further diagnostics of the

electronic controls with the use of the Service LED on the main control board. Details on Consumer Error

Mode and Service Mode, as well as Service LED are located in the Electronic Control section of this guide.

To view the Service LED, disconnect power, lower the control box bottom cover and reapply power to the

dishwasher when the control is in a safe position.

Flashing Lights

Flashing LED's or Displays (some models) are an indication that the control is waiting for a start command or

that the door is in the open position. There are no fault codes that will automatically display or cause a no-

run condition. If board communications are an issue, look for a fault on the main control board Service LED.

All of the above diagnostics are covered in this service guide.
