How to Clean Your Washing Machine Filter

A clogged washing machine filter is one of the most common causes of drainage problems, bad odours, and poor wash performance. The good news? Cleaning it yourself takes just 15 minutes and can save you a repair callout.

Where Is the Filter?

Most front-loading washing machines have a filter (also called a pump filter or drain filter) located at the bottom front of the machine, usually behind a small panel or flap.

Common locations by brand:

Bosch/Siemens: Bottom right, behind a round panel
Samsung/LG: Bottom left or right, behind a rectangular panel
Hotpoint/Indesit: Bottom right, behind a kick plate

Before You Start

Always turn off and unplug your washing machine before accessing the filter. There will be water spillage, so have towels ready.

Step-by-Step Guide

Step 1: Prepare for Water

Place a shallow dish or towel beneath the filter access panel. When you open the filter, water will drain out – sometimes quite a lot if the machine hasn't been draining properly.

Step 2: Open the Access Panel

Locate the small door or panel at the bottom front of your machine. It usually clips open or has a small catch you can press.

Step 3: Drain Residual Water

Many machines have a small drain hose next to the filter. Pull this out and let water drain into your dish. If there's no drain hose, the water will come out when you remove the filter – slowly unscrew to control the flow.

Step 4: Remove the Filter

Twist the filter anticlockwise to unscrew it. Pull it straight out once loose.

Step 5: Clean the Filter

Remove any debris – you'll often find coins, hair clips, tissues, and lint. Rinse the filter under running water and use an old toothbrush to remove stubborn buildup.

Check inside the filter housing too! Shine a torch in and remove any debris caught in the pump impeller (the propeller-like part at the back).

Step 6: Replace the Filter

Screw the filter back in clockwise until hand-tight. Make sure it's secure to prevent leaks.

Step 7: Close and Test

Replace the access panel and run a quick rinse cycle to check for leaks.

How Often Should You Clean It?

We recommend cleaning your washing machine filter every 1-3 months, or more frequently if you:

Wash items with lots of lint (towels, blankets)
Have pets that shed
Notice your machine draining slowly

When to Call an Engineer

If cleaning the filter doesn't solve your problem, there may be a blockage further in the drain system or an issue with the pump itself. Get a fixed price quote for a professional diagnosis and repair.
