Washing Machine Won't Drain

Electrolux Medium fix Updated 2 August 2026
Quick Fix

Check the drain hose, household drain and the user-accessible pump filter exactly as the model manual describes (about 5–30 minutes).

Fault description

The washer cannot pump out its water.

Check the drain hose, household drain and the user-accessible pump filter exactly as the model manual describes. Switch off and unplug before accessible cleaning and never use force.

Causes

  • Drain hose restriction — The hose may be kinked, blocked or installed incorrectly.
  • Blocked household drain — A sink trap or standpipe can prevent discharge.
  • Blocked accessible pump filter — Lint or small objects may obstruct the filter on models that provide user access.
  • Internal drain fault — A pump, level system or internal blockage requires diagnosis.

Step-by-Step Fix

  1. 1

    Stop safely

    Pause the programme, wait for the drum to stop and do not force the door.

  2. 2

    Check external conditions

    Check the drain hose, household drain and the user-accessible pump filter exactly as the model manual describes.

  3. 3

    Follow the exact manual

    Use the product number for the correct procedure; remove no panels and improvise no emergency release.

  4. 4

    Make one controlled test

    Test once only when there is no leak, burning smell, smoke, heavy scraping noise or electrical fault.

  5. 5

    Arrange authorised service

    Stop troubleshooting if the fault returns or an internal component is suspected.

Related error codes

  • E20 Drainage error. The machine cannot drain water within the set time. Check the drain filter, hose, and pump.
  • E21 Drainage pump fault. The pump is not running correctly. Check for blockage or pump failure.
  • E23 Drain pump electronic fault. The pump's electronic components have failed.
  • E24 Drain pump triac faulty. Electronic control of the drain pump has failed.
  • E25 Drain pump blocked. The pump impeller is obstructed. Check and clean the drain filter and pump.

When to call a service technician

Arrange authorised service if the fault remains after external checks, if the drum does not move normally or if the lock, pump, valve, sensor or mechanics are suspected.

Switch off immediately for water near electricity, burning smell, smoke, abnormal heat, tripped protection or severe grinding, scraping or impacts.

Prevention

Empty pockets, dose correctly, mix large and small items, avoid overloading and clean user-accessible filters and hoses at the manual's intervals.

Keep the washer stable and hoses free from pinching; this does not prevent internal component faults.

Frequently Asked Questions

Can I keep using a Bosch washer showing —?

Check the drain hose, household drain and the user-accessible pump filter exactly as the model manual describes. Do not run another cycle until Bosch guidance or service confirms it is safe.

Can I reset — by switching the washer off?

Switching off is a safety step, not proof that the fault is repaired. If the code returns or Bosch classifies it as service-only, do not repeatedly reset the washer.

Does — identify a part to replace?

No. The code identifies a system or condition, but Bosch service should diagnose the exact cause before any part is ordered.

Why should I provide the E-Nr?

Bosch model families and markets can use different hardware and service procedures. The E-Nr identifies the correct appliance documentation.

May I test the sensor myself?

No. Do not remove panels or measure internal wiring, sensors or electronics. Bosch directs these codes to customer service.
