Candy E01 on a washer dryer

Door lock fault — the machine cannot confirm the door is closed.

The same code appears on Hoover machines — they share the same control platform.

What E01 actually means

The interlock never confirmed the door was latched, so the cycle will not start. On this platform a failed interlock is a genuinely common cause, but check the seal for trapped laundry first — it costs nothing and fixes it more often than not.

What causes it, most likely first

  1. Laundry caught in the door seal

    Most likely

    A trapped corner of fabric holds the door fractionally proud so the latch misses its catch.

    How to check: Open the door and run a hand right round the seal.

  2. Door not closed firmly

    Common

    The door needs a positive push until it clicks audibly.

  3. Failed door interlock

    Common

    Interlocks are a known wear point on this platform. The door latches mechanically but the contacts no longer report to the board.

  4. Broken wire to the interlock

    Occasional

    The loom to the lock flexes with vibration and can fracture inside its insulation, mimicking a dead lock.

How to fix it, step by step

  1. Clear the seal and close firmly

    Run a hand round the whole seal, remove anything caught, and push the door until it clicks.

    2 min

  2. Power-cycle

    Switch off at the wall for a full minute, then restore power and try again.

    3 min

  3. Inspect the catch

    Check the hook on the door edge for wear or cracks, and watch whether the door drops as it swings.

  4. Replace the interlock if it persists

    A cheap part, but reaching it means working behind the door seal retaining band with the machine isolated.

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.

  • Wiring loom / connector

    £10–£45

  • 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.
