What is the washing machine residue filter used for

What is the purpose of the washing machine residue filter?
The residue filter, that little door at the bottom of the washing machine, is where certain items can end up, which were initially among your laundry. If you've ever wondered where your socks or coins disappeared to during the wash cycle, chances are they're there. We're talking about the siphon door.

The siphon is very useful. It prevents small objects from entering the main drain, which is responsible for draining water from the machine through the drain hose. If your washing machine is not draining properly or you notice that a sock or button is missing, consider taking a look at the siphon to inspect it and clean it if necessary. This is an easy task that will only take a few moments.
