What to check, in order
- Deal with the foam
If there's lots of foam, switch off and leave it a few hours to settle. Use less detergent next time and clean the detergent drawer.
- Drain the base tray
Disconnect the water and power, tilt the machine back so the front is 10 to 15 cm off the floor for 30 to 40 seconds, and let any water run out onto a towel laid behind the machine.
- Check the usual leak points
Refit the fluff filter hand-tight, and check the inlet hose and the door seal.
- Rebalance the load
If the load is lopsided, spread it out.

Good to know
- Once the cause is fixed, the warning clears by itself at the end of the programme or when you restart.
Quick answers
What does the Electrolux EF0 error code mean?

Can I fix Electrolux EF0 myself?
Moderate (about 30 minutes). Start with: deal with the foam; drain the base tray; check the usual leak points. If it happens again.
Is Electrolux EF0 worth repairing?
Worth fixing. Usually foam or a loose filter, but a real leak needs finding before it damages the floor.
