What the E7 Error Code Means
The E7 error code indicates a malfunction with the heating element — the component responsible for heating the water during the wash and rinse cycles. When the heating element fails or cannot reach the required temperature, the dishwasher stops the programme and displays E7.
Common Reasons This Error Appears
Faulty heating element
The heating element has failed and is no longer generating heat to warm the water during the wash cycle.
Limescale build-up on the heating element
In hard water areas, heavy limescale deposits on the heating element can reduce its efficiency until it can no longer heat water to the required temperature.
Faulty temperature sensor
A faulty NTC temperature sensor may incorrectly report that the water is not heating, even if the heating element is functioning correctly.
Wiring fault
A loose or damaged connection to the heating element or temperature sensor can prevent the heating circuit from operating correctly.
Control board fault
An issue with the main electronic control module can prevent it from correctly managing the heating circuit.
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 descaler may help remove limescale deposits from the heating element and restore performance.
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 fault.
If the error persists after a reset and descaling attempt, the heating element will need to be inspected by a qualified engineer.
