Checking and Cleaning the FilterWashing machines contain a filter between the drum and the pump. This is to prevent any loose items left in the washing such as coins from damaging the pump. If the filter becomes blocked this can result is poor water drainage and sometimes leaks.

Removing the FilterBefore removing the filter make sure the washer has finished and there is no water left in the machine. There will still be a small amount of water that comes out that is left in the bottom of the pipes. Most filters have a rubber seal that is made water tight with a screw.
