Error Code Condition Check/Repair Shop Parts
4E No water detected in the tub for 5 minutes after starting the dishwasher Make sure that the water supply cut-off valve for the dishwasher is fully open. Unplug the dishwasher and shut off the water supply, and then disconnect the fill line and examine the water inlet valve. If the inlet screen is clogged, replace the water valve—don’t just clean the screen, because debris could enter the valve body, causing the valve to stay open, resulting in flooding. Check the wiring connections on the water inlet valve and secure any loose connections. If the water valve won't open when activated, replace it.

If the temperature is above 120 degrees, lower the setting on the water heater. If the water temperature is below 176 degrees, the thermistor (temperature sensor) is defective. Replace the thermistor. If the problem persists, replace the main power board assembly (PBA).

If the water is less than 176, the thermistor (temperature sensor) is likely defective. Replace the thermistor. If the problem persists, replace the main PBA.
