Quick answer

On an Electrolux tumble dryer, E20 (or C2, or 2 beeps or flashes) means a drainage, pump or software problem. If you use the direct drain, check the rear hose is connected and not kinked, and unplug for 30 seconds to reset.

Safety first

Stop and check this first

  • If a misplaced hose lets water onto the floor, unplug the dryer before drying the area.

Safe checks you can perform

  • Direct drain hose connection
  • Hose route and length
  • 30 second reset
  • Drain pump check

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Pump and control check
  • Do not attempt this professional task: Drain test

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Pump and control check

    What they doThe technician tests the drain pump with the cover off and checks the control using the manufacturer procedure.

    They must show youthe pump working or the measured fault, and the control checked.

    In writingthe cause found, any replaced part with its reference and the reason.

  2. Drain test

    What they doThe technician runs a programme with a damp load and checks water leaves through the hose with no E20.

    They must show youwater leaving through the hose during the cycle.

    In writingthe programme tested, the result and the date.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Direct drain hose connection

    No special tools

    Who:
    you, no tools, dryer unplugged.
    How:
    if your dryer uses the direct drain, check at the back that the red or green hose reaches a drain.
    Result that matters:
    the hose connected and not loose.
    If the hose was loose or misplaced:
    connect it as the manual shows and try again.
    If your dryer uses the tank and no hose:
    this check does not apply; go on to the reset.
    Evidence to keep:
    a photo of the back and the hose end.

    Evidence: Tumble dryer displays error message E20, C2 or emits 2 beeps / 2 flashes

  2. Hose route and length

    No special tools

    Who:
    you, no tools.
    How:
    follow the hose looking for kinks or blockages; Electrolux says to shorten it so it hangs down freely into the drain.
    Result that matters:
    a straight hose hanging freely.
    If it was kinked or had spare length:
    correct it; if E20 clears, that was the cause.
    If it was fine:
    the hose is ruled out; reset the dryer.
    Evidence to keep:
    photos of the hose before and after.

    Evidence: Tumble dryer displays error message E20, C2 or emits 2 beeps / 2 flashes

  3. 30 second reset

    No special tools

    Who:
    you.
    How:
    unplug the dryer for 30 seconds, plug it back in and select a programme.
    Result that matters:
    whether E20 comes back.
    If it does not:
    it was a one off hang; watch the next cycles.
    If it returns with the hose correct:
    it points to pump or software; book a service visit.
    Evidence to keep:
    a note of the date and whether the code returned.

    Evidence: Tumble dryer displays error message E20, C2 or emits 2 beeps / 2 flashes

  4. Drain pump check

    Tools required

    Who:
    an authorised service technician.
    How:
    with the dryer disconnected, they check the pump works and water reaches the hose.
    Result that matters:
    whether the pump moves water.
    If the pump does not pump:
    it confirms the cause.
    If it works:
    the technician must check software or control.
    Evidence to keep:
    a job sheet with what was checked.

    Opening a dryer connected to the mains is technician work.

What it means

Electrolux describes E20 on tumble dryers as a drainage, pump or software problem. On models with a direct drain, condensed water leaves through a red or green rear hose to a drain instead of filling the tank; the pump pushes it along that hose. The code does not separate a badly connected, kinked or blocked hose, a pump that does not drain, or a software hang, and on its own it does not prove the pump is faulty.

Warnings and stop conditions

  • Mediumeditorial warning

    If a misplaced hose lets water onto the floor, unplug the dryer before drying the area.

    Evidence: Tumble dryer displays error message E20, C2 or emits 2 beeps / 2 flashes

Symptoms and causes

Probable causes · in order

  • Drain hose not connectedCommon

    On dryers using the direct drain, the red or green rear hose must go to a drain; you tell by checking where it ends.

    Evidence: Tumble dryer displays error message E20, C2 or emits 2 beeps / 2 flashes

  • Hose kinked, blocked or too longPossible

    Electrolux says to shorten it so it hangs down freely into the drain; you see it by following the route.

    Evidence: Tumble dryer displays error message E20, C2 or emits 2 beeps / 2 flashes

  • Pump or softwarePossible

    If the hose is fine and E20 stays after a reset, Electrolux refers you to an authorised service centre.
