E04 Arçelik washing machine error E04 — overfill

What it means

If your Arçelik washing machine shows E04: the water level is higher than allowed and the overflow protection has tripped.

Likely causes

Inlet valve stuck open, faulty water level sensor (pressure switch) or a blocked sensor tube.

Safe steps you can try

Turn off the tap and switch the appliance off. Switch it on again after a few minutes — it should pump out the extra water itself.

When to call a technician

If it fills again as soon as the tap is opened, the inlet valve or level sensor must be replaced; do not leave it connected.
