AEG washer displays E33 and may not heat or may stop during wash

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect water level detection for heating, Faulty dual-level pressure switch, Wiring issue between pressure switch and control board, Control board fault

How to Fix / Troubleshooting

Safety first: Disconnect mains power and allow the machine to cool before working near the heater.

Inspect pressure switch: On models with a dual-level switch, check that the connector is secure and the hose is clear.
Check wiring: Trace the wires from the pressure switch to the control board for damage or loose plugs.

Because E33 involves safety interlocks for the heater, if basic checks do not resolve it, contact an AEG technician to test and replace the pressure switch or control board.
