This troubleshooting section is an overview of 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 are possible 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 Display (some models) is 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.
