How to clean the filter of your washing machine and unblock the pump?

A lot of minor faults with washing machines can be traced back to the filter. If your washing machine is vibrating, making a loud noise, taking longer to complete a cycle, stopping randomly during a cycle, or the washing is coming out wet, the chances are that you have a clogged filter.

It is also common for small foreign objects, such as buttons and coins, to become trapped in the filter which can prevent the impeller from turning.

Thankfully this can be quickly and easily resolved with simple cleaning and maintenance of the filter. Cleaning the washing machine filter regularly will also prevent future faults with your washing machine.

Step by step guide: How to clean the washing machine filter and to unblock the pump in 10 steps:

Warning: Risk of scaling: When you wash at high temperatures, the water gets very hot. If you come into contact with the hotwater, you may be scaled. Allow the water to cool down.

1. Turn off the water tap so that no more water can flow in and has to be drained via the drain pump.

2. Switch off the appliance. Pull out the main plugs.

3. Open and remove the service flap.

4. Lay a towel on the floor and unclip the pump cover.

You will find a drain hose which can be used to release residual water into a tray or shallow container. Pull the end of the drain hose out over the bowl, take off the drain hose cap and allow the water to flow into the tray or container. You might need to drain the water into the tray or container multiple times. Please be careful, the water might be hot when doing this procedure directly after a wash cycle.

5. Once you have drained all the water, make sure you have replaced the sealing cap and drain hose.

6. Carefully unscrew the pump cover; residual water may leak out. Unscrew the filter cap and slide it out. Water will come out onto the towel you have laid down. You may find obstructions in the filter such as coins, buttons or a build-up of lint. These should be removed before thoroughly cleaning the filter.

7. Clean the interior, pump-cover thread and pump housing. The impreller in the drain pump must be able to rotate. Carefully check if the impeller moves freely. Use a spoon or stick to test it.

8. Once this is done, screw the filter cap back tightly into the locked vertical position. Refit the pump cover and screw it on tightly. The handle must be in a vertical position.

9. Put the service flap back on, lock it into place and close it.

10. You can then turn on the water supply and power again.

NOTE: To prevent unused detergent from flowing straight into the drain during the next wash, pur 1 litre of water into compartment “liquid detergent” and start the drain programme.
