TLDR :

• Most machines have a filter behind the lower front flap.
• Put a towel down — water will spill.
• Twist the filter cap out, remove debris, rinse, refit.
• Clear the drain pump area and check for coins, lint, hair ties, etc.
• Do this every few months to avoid drainage issues.

Introduction

A blocked filter is one of the most common reasons a washing machine won’t drain properly. This guide shows you exactly how to clear it safely and quickly.

Step-by-Step: Cleaning Your Washing Machine Filter

1. Switch the machine off

Turn it off at the button and wall.

2. Find the filter flap

Usually bottom-right on the front. Integrated machines may need the plinth removed.

3. Prepare for water

Lay down a towel and use a shallow tray. If your machine has a drain hose, empty it first.

4. Open the filter

Turn anti-clockwise slowly to control the water release. Remove the filter assembly.

5. Clean out debris

Typical things that block the filter:

• Hair clips
• Coins
• Elastic bands
• Lint and fluff
• Bra underwire pieces or small metal bits

Rinse the filter under the tap until it’s clear, then check the rubber seal isn’t split, twisted, or missing.

6. Check inside the pump housing

Check inside the pump housing Shine a torch in and remove any visible debris. The impeller should turn with slight resistance.

7. Refit the filter

Insert and twist clockwise until snug. Hand-tight only, don’t use pliers.

8. Run a quick rinse cycle

This clears remaining debris and confirms the seal is tight and that the machine is draining properly.

Common Mistakes

“I didn’t find anything — must be broken.”
Blockages can sit further back in the pump or sump.

“The filter won’t open.”
Don’t force it — this can crack the housing.

“My machine doesn’t have a filter.”
Some models hide it well, but most UK machines still have one.

When to Clean Your Filter

Every 2–3 months for normal households. Monthly if you wash pet items, long hair, or lots of small garments.

When to Call an Expert

If the machine still won’t drain, the impeller doesn’t spin freely, the filter won’t open, or you can hear the pump humming with no movement, it normally means the blockage is deeper in the sump or pump housing. At that point, it’s quicker and safer for an engineer to sort it.
