This error code signifies a communication issue between the dishwasher’s control panel and its main circuit board. Fortunately, with a little troubleshooting and the right steps, you can resolve this error and get your dishwasher back to its sparkling clean routine.

Understanding the E4 Error

The E4 error typically occurs when the dishwasher’s control panel fails to receive a signal from the main circuit board. This communication breakdown prevents the dishwasher from completing its wash cycle, leaving you with dirty dishes and a lingering frustration.

Troubleshooting the E4 Error

1. Reset the Dishwasher:

• Unplug the dishwasher from the power outlet.
• Wait for 60 seconds.
• Plug the dishwasher back in and check if the error has cleared.
