Beko Dishwasher Error Code E04
Overflow / anti-flood triggered
Common Causes
- 1Leak into the base tray tripped the float switch
- 2Inlet valve stuck open
- 3Sump or door seal leaking
- 4Float switch failed
Water near the base electronics is a shock risk. Isolate power at the breaker before tipping the unit or drying the base tray.
Step-by-Step Troubleshooting
- 1
Unplug the dishwasher and close the supply tap
- 2
Tip the unit gently back and check the base tray for standing water under the tub
- 3
Dry the base tray and inspect the sump gasket, hose clamps, and door seal for the leak source
- 4
Verify the anti-flood float in the base moves freely and is not stuck up
- 5
Correct the leak, dry the tray fully, and confirm the float resets before restoring power
Pro Diagnostic Tip
E04 latches once the base float lifts and will not clear until the tray is dry AND the float drops. Drying the tub alone leaves the code active — the water pools under the tub, out of sight.
