How to Clean the Washing Machine Filter and Why It Matters

Among the household appliances used most often, the washing machine rarely gets much attention when it comes to cleaning. Yet one overlooked part in particular-the filter-has a direct impact on wash performance, how hygienic your clothes are afterwards, and even how much electricity the machine uses.

Why is it important to clean the washing machine filter?

The filter catches lint, hair, small objects and soap residues that come loose from fabrics during a cycle. When it becomes clogged, water can no longer flow as it should, so the machine has to work harder to finish the programme-raising wear and tear and increasing energy consumption.

From a hygiene perspective, skipping this maintenance creates a damp environment where mould and bacteria can thrive, then spread through the drum and hoses. The knock-on effects include laundry that smells unpleasant even after washing, as well as a higher chance of faults, unusual noises and, on newer models, error messages.

How often is it recommended to clean the washing machine filter?

How frequently you should clean it depends on how often the washer is used and what you tend to wash. For households running several loads a week, technicians generally advise cleaning it every 15–30 days, shortening that interval when usage is heavy-for example, very dirty workwear, bulky bedding, or pet items.

The machine type matters too, because top-loading and front-loading models use different filtration systems. On some machines, the filter is visible inside the drum; on others, it sits at the lower front behind a small flap. Even if you follow the manual, professionals note that slightly more frequent cleaning helps prevent blockages and unexpected stops during rinsing or spinning.

What signs show it is time to clean the washer filter?

Certain day-to-day behaviours act as “silent warnings” that the filter is dirty. Noticing these changes early can help you avoid bigger damage and schedule maintenance before the issue becomes more serious.

A persistent bad smell coming from the drum or the outside of the machine.
Clothes coming out with lots of lint, pet hair or small debris after washing.
Standing water, or the drum taking an unusually long time to drain at the end of the cycle.
Different or louder noises during draining or spinning.
Error messages on the display, or the programme stopping before it finishes.

How to clean the washing machine filter and what benefits does this bring?

The basic cleaning process is straightforward and can usually be done by anyone at home. Start by switching the appliance off at the mains, then find the filter (in the drum, on the inner side panel, or at the lower front). Remove it carefully, rinse it under running water-using a soft brush if needed-and check the housing for built-up debris before refitting the part securely.

This quick routine delivers practical benefits: it improves washing performance, reduces strain on the pump, hoses and motor, lowers the risk of blockages, helps keep internal odours under control, and can extend the washing machine’s working life-reducing the chance of unexpected repair costs.
