E0

No fault codes are recorded

Check/Repair

No component problems were detected. When you enter the diagnostic test mode and retrieve saved fault codes from the control memory, this E0 code is displayed when no fault code is recorded.

Possible parts
E1

Heating problem

Check/Repair

Check the water fill level. If water level is too low, the heater won't turn on. If the water level is okay, the flow switch or the heater could be defective. A service technician usually needs to diagnose and repair a heating failure because accessing the heater requires removing the dishwasher tub.

Possible parts
Heater, Flow switch
E2

Temperature sensor defective

Check/Repair

A service technician usually needs to diagnose and repair a temperature sensor problem because accessing the sensor requires removing the dishwasher tub.

Possible parts
Temperature sensor (also called negative temperature coefficient, or NTC)
E3

Not filling

Check/Repair

If the water supply cut-off valve for the dishwasher is fully open and the dishwasher still won't fill, shut off the water supply, unplug the dishwasher, disconnect the fill line and check whether the screen in the water inlet valve is clogged. If it's clogged, replace the water valve-don't just clean the screen, because debris could fall into the valve body, prevent the valve from closing, and cause flooding. If the dishwasher still won't fill, have a service technician diagnose and repair the dishwasher.

Possible parts
Water inlet valve
E4

Water switch defective

Check/Repair

A service technician usually needs to diagnose and repair a water switch problem because accessing the sensor requires removing the dishwasher tub.

Possible parts
