How-to guide

How to clean a washing machine pump filter

A blocked pump filter is one of the most common reasons a washing machine won’t drain or spin. Cleaning it takes about 15 minutes, needs no tools on most machines, and could save you a call-out.

  • Time 15 to 20 minutes
  • Difficulty Easy
  • How often Whenever the machine is slow to drain or shows a drain error, and every few months as routine. Your manual may give a specific interval.
Before you start

What you’ll need

  • Old towels
  • A shallow tray or baking dish, as the water comes out close to the floor
  • A bucket to empty the tray into
  • A coin, on some models, to open the hatch

Safety first

  • Expect more water than you think, especially if the machine stopped mid-cycle.
  • Never open the filter while the machine is running or full of hot water.
  • Tighten the filter properly. A loose filter will leak on the next wash.
Step by step

7 steps

  1. Switch off and unplug

    Turn the machine off and pull out the plug. If it has just run a hot wash, wait for the water to cool before you start.

  2. Open the access hatch

    The filter sits behind a small hatch at the bottom front of the machine. Depending on the model, press the hatch to open it or lever it open with a coin.

  3. Drain the water

    Lay the towels down and put the tray in front of the hatch. If there’s a small emergency drain hose, pull it out, remove its cap and let the water run into the tray, emptying it as you go. If there’s no hose, unscrew the filter slowly, a little at a time, so the water comes out gradually.

  4. Remove the filter

    Once the water stops, refit the cap on the drain hose and push it back in. Turn the filter anti-clockwise and pull it out.

  5. Clean the filter

    Pull off any fluff, hair, coins or hair grips, then rinse the filter under warm water.

  6. Clean the housing

    Wipe inside the filter opening with a damp cloth. If you can see the pump impeller, check it turns freely and nothing is wrapped around it.

  7. Refit and test

    Screw the filter back in firmly and close the hatch. Plug in, pour about a litre of water into the detergent drawer and run a drain or spin programme, watching the filter for leaks.

Still not working?

When to call an engineer

If the filter was clean and the machine still won’t drain, or you can hear the pump humming but no water moves, the drain pump or a blockage further along is the likely cause. That needs an engineer.
