No fault codes are recorded
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.
Heating problem
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.
Temperature sensor defective
A service technician usually needs to diagnose and repair a temperature sensor problem because accessing the sensor requires removing the dishwasher tub.
Not filling
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.
Water switch defective
A service technician usually needs to diagnose and repair a water switch problem because accessing the sensor requires removing the dishwasher tub.
Overfilled
Unplug the dishwasher or shut off the house circuit breaker to disconnect electrical power. If the dishwasher continues to fill, replace the water inlet valve assembly.
Aqua sensor defective
The aqua sensor detects how dirty the water in the dishwasher is. A service technician usually needs to diagnose and repair an aqua sensor problem because accessing the sensor requires removing the dishwasher tub.
