How to clean your Bosch washing machine filter

A blocked filter stops water draining and leaves clothes wet. Clean it every 1-2 months to keep your machine running smoothly.

Difficulty: Easy
Time: 15 min

Step-by-step

  1. 1

    Switch off and unplug machine

    Turn the power off at the wall socket. Wait 5 minutes for the system to depressurise.

    💡 Never work on a plugged-in appliance.

  2. 2

    Locate the filter access panel

    Look at the bottom right of your Bosch washer. You'll see a small cover panel that twists or clips off.

    💡 Consult your manual if you can't find it—panel location varies by model.

  3. 3

    Place towel underneath panel

    Water will spill when you open the filter. Lay a towel or place a shallow tray beneath.

  4. 4

    Unscrew the filter slowly

    Turn the filter anticlockwise by hand. Go slowly—residual water will leak out.

    💡 If stuck, grip with a cloth for better traction.

  5. 5

    Remove debris and rinse filter

    Check inside the filter pocket for coins, threads, and lint. Rinse the filter under warm tap water.

    💡 Use an old toothbrush to scrub stubborn buildup.

  6. 6

    Clean the filter housing

    Wipe the filter opening and housing with a damp cloth. Remove any debris left inside.

  7. 7

    Screw filter back in clockwise

    Insert the clean filter and turn clockwise until snug. Don't over-tighten.

    💡 Hand-tight is sufficient—forcing it can strip the threads.

  8. 8

    Replace the access panel

    Snap or twist the cover back into place. Plug the machine back in.

  9. 9

    Run a rinse cycle to test

    Start a short rinse cycle to check for leaks around the filter area. Water should drain normally.

    💡 If water pools, the filter may not be seated properly—repeat step 7.

⚠️ Always disconnect your appliance from mains power before starting any repair. If in doubt, consult a qualified engineer.

FAQs

How often should I clean the filter?
Clean it every 1-2 months during normal use, or more frequently if you wash heavily soiled items.
Why is water still not draining after cleaning?
The drain hose may be kinked or blocked, or the pump itself may be faulty. Check the hose runs downhill without traps.
Can I damage the filter by cleaning it?
No—gently rinse it under warm water or use an old toothbrush. Avoid harsh chemicals or high-pressure jets.
