What the E4 Error Code Means
The E4 error code indicates a malfunction with the temperature sensor — the component that monitors water temperature during the wash cycle. When the sensor fails or gives readings outside the expected range, the dishwasher stops the programme as a precaution to prevent overheating or incorrect wash temperatures.
Common Reasons This Error Appears
Faulty NTC temperature sensor
The temperature sensor has failed and is providing incorrect readings to the control board, causing the machine to stop the cycle.
Wiring fault
A loose or damaged connection between the temperature sensor and the control board can cause incorrect or no readings to be reported.
Control board fault
An issue with the main electronic control module can affect its ability to correctly read temperature sensor data.
Limescale build-up
In hard water areas, limescale deposits on the sensor can affect its accuracy over time.
Safe Checks You Can Try
Run a hot cleaning cycle
If you live in a hard water area, running the dishwasher empty on the hottest programme with a dishwasher cleaner may help remove limescale deposits that could be affecting the sensor.
Restart the dishwasher
Switch the machine off at the mains and leave it unplugged for a few minutes. Reconnect the power, switch back on and restart the programme. A power reset can sometimes clear a temporary sensor fault.
If the error persists after a reset, the temperature sensor will need to be inspected by a qualified engineer.
