What E20 actually means
The machine can't get the water out, and Electrolux flags it as a blocked drain filter.
E20 comes up when the machine tries to pump the water away and the level doesn't drop as it should. Electrolux treat it as a user-fixable warning rather than a hard fault "Check drain filter" on models with a text display and it will pause the cycle mid-way, usually with water still in the drum, and beep in short bursts until the problem is dealt with.
What usually causes it
- Drain filter (pump filter) blocked with lint, coins, hair grips or bits of tissue
- Drain hose kinked, squashed behind the machine or pushed too far into the standpipe
- Blocked sink trap or standpipe where the hose empties
- Something jammed in the drain pump itself, so it hums but shifts no water
- Failed drain pump or a pressure/level sensor that wrongly reads water still in the tub
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Turn the machine off at the socket for a minute, then switch back on \u2014 if the cause has cleared, the warning goes
- Clean the drain filter at the front bottom of the machine (lay towels down first, the drum water comes out here) and check for coins, buttons or fluff
- Look behind the machine and make sure the drain hose isn't kinked, trapped or crushed against the wall
- If it drains into a sink waste or standpipe, check that isn't blocked \u2014 a slow-draining sink is a strong clue
- Run a short rinse and spin afterwards to see whether it now empties properly
When to call someone
This sometimes clears with the checks above. If it comes back, it needs looking at properly. We cover Nottinghamshire, Derbyshire and Leicestershire, and it's £66 including VAT for an engineer to come out and diagnose it — £84 in total if it's repaired on the visit with no parts needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
Outside our area? The explanation above still stands — take it to a local engineer and tell them the code. Knowing it saves them time and you money.
