What the E04 Error Means
The E04 error code indicates an electronics fault within the dishwasher that has caused the programme to stop. This is part of a series of electronics fault codes — E01 through E06 — that point to problems within the internal control system. The machine cannot safely continue the cycle until the fault is identified and resolved.
Common Reasons This Error Appears
Main control board fault
A fault within the main electronic control module can cause the programme to stop and this error to be displayed.
Power supply interruption
A sudden power cut or voltage fluctuation during a cycle can cause the electronics to register a fault and halt the programme.
Wiring fault
A loose or damaged connection within the control system can disrupt communication between components and cause the programme to be interrupted.
Component fault
If a component connected to the control board develops a fault mid-cycle, the board may stop the programme and display an electronics error code.
Safe Checks You Can Try
Restart the dishwasher
Turn the appliance off at the mains and leave it for a few minutes before restarting. This can clear a temporary electronics fault caused by a power fluctuation or glitch.
Check the power supply
Ensure the dishwasher is plugged directly into a wall socket rather than an extension lead, and that the socket is functioning correctly.
