On Electrolux washers, E10 means a water fill problem, E20 means a drain problem, and E40 (with E41) means the door or lid is not detected as properly closed and locked. Each points to a different stage of the cycle, and each has its own short list of common causes.
What each code means
These are three separate faults sharing similar numbering. E10 fires during the fill stage, E20 during the drain stage, and E40 is a safety check on the door lock circuit that runs before the cycle can proceed at all.
E10 — water fill problem
| Cause | How likely | What to look for |
|---|---|---|
| Water supply turned off | Very common | Tap closed or supply shut off elsewhere |
| Kinked inlet hose | Common | Hose bent behind the machine |
| Clogged inlet valve or filter | Common | Slow or absent fill despite an open tap |
| Low water pressure | Occasional | Other taps in the house also weak |
Press Pause/Cancel twice to stop the cycle and drain any residual water, then unplug the washer for three to five minutes to reset the control board. Confirm both hot and cold supply valves at the wall are fully open and the hoses are not kinked before restarting.
E20 — drain problem
| Cause | How likely | What to look for |
|---|---|---|
| Coin trap, hose or pump blockage | Very common | Debris in the filter or drain path |
| Failing drain pump motor | Less common | Pump silent or humming with no drainage |
| Drain hose inserted too far into the standpipe | Occasional | Should not exceed about 8 in into the standpipe |
Clean the drain filter and check the hose for blockages and kinks, and confirm the hose is not pushed further than roughly 8 in into the standpipe.
E40 — door lock fault
E40 is a general safety fault — the control board cannot verify the door is securely closed and locked. Make sure the door is fully closed and push firmly until you hear the lock click; check for clothing stuck between the door seal and the glass. If it persists, unplug the washer for 10–15 minutes and try again, and inspect the wiring to the door lock module for looseness or corrosion.
If the door closes properly and E40 still appears, the fault is most often the door lock assembly itself or, less commonly, the main control board.
When to call a professional
Have a technician diagnose E10 if the water supply and hoses are confirmed clear, E20 if the filter and hose are clean but drainage still fails, and E40 if the door closes properly but the lock still will not register — this can involve replacing the door lock assembly or, less often, the control board.
Stop and call a qualified appliance technician or electrician if you find scorched or melted wiring, smell burning, see water that has reached electrical components, or if the fault returns immediately after a repair. Never bypass a safety device — thermal fuses, door interlocks and flood switches fail for a reason, and defeating one converts a broken appliance into a fire or flood risk.
