Grundig E01 on a washing machine
Door lock fault — the machine cannot confirm the door is secured.
The same code appears on Beko and Blomberg machines — they share the same control platform.

What E01 actually means
The control board never received confirmation from the interlock that the door was latched, so it will not start the cycle. Start with laundry trapped in the seal, which accounts for most cases, before assuming the lock itself has failed.
What causes it, most likely first
Laundry caught in the door seal
Most likelyA trapped corner of fabric holds the door fractionally open so the latch misses its catch.
How to check: Open the door and run a hand right round the seal.
Door not closed firmly
CommonThe door needs a positive push until it clicks audibly.
Worn catch or dropped hinge
CommonThe plastic hook wears or the door sags so it no longer enters the lock squarely.
Failed door interlock
OccasionalThe lock latches mechanically but its contacts no longer report to the board.

How to fix it, step by step
Clear the seal and close firmly
Run a hand round the whole seal, remove anything caught, and push the door until it clicks.
2 minPower-cycle
Switch off at the wall for a full minute, then restore power and try again.
3 minInspect the catch
Check the hook on the door edge for wear or cracks and watch whether the door drops as it swings.
5 minTorchReplace the interlock if it persists
A cheap part, but reaching it means working behind the door seal band — a short engineer visit if you would rather not.

Parts you might need
Typical UK prices for the part alone, before fitting. Worth knowing before you accept a quote — the part is often a small share of what a repair is priced at.
Door interlock
The electrically operated latch that proves the door is shut before the machine will fill, and holds it shut until the drum stops.
£15–£40
Worth repairing, or replace it?
At the top of this range the repair costs a significant share of a graded replacement, which typically starts around £200. Worth getting the quote first, then deciding — on a machine under about five years old a repair usually still wins.
