What the E09 Error Means
The E09 error code indicates a heating system fault. The dishwasher heats water during the wash and rinse phases to clean and sanitise dishes effectively. If the heating element or associated components are not functioning correctly, the machine will stop and display this error. In some cases this can also indicate overheating within the heating circuit.
Common Reasons This Error Appears
Failed heating element
The heating element may have burned out and is no longer able to heat the water to the required temperature.
Faulty temperature sensor or NTC
If the temperature sensor is giving incorrect readings, the control board may believe the water is not heating correctly or that the system is overheating.
Scale build-up on the heating element
In hard water areas, limescale deposits can coat the heating element and reduce its efficiency, eventually causing a fault.
Wiring fault
A loose or damaged connection to the heating element or temperature sensor can disrupt the heating circuit and trigger this error.
Safe Checks You Can Try
Run a descale cycle
If you live in a hard water area, running a dishwasher cleaner or descaler through the machine may help remove limescale from the heating element and improve performance.
Restart the dishwasher
Turn the appliance off at the mains for a few minutes before restarting to clear any temporary fault.
