Bosch Classixx Filter Blockage

[sahlaek]

My front loader wasn't draining properly so I tried to remove the filter and clean it but the cap was jammed. So after turning it on its side and unclipping the pipe I removed what looks like a filter sock. It's about an inch wide, 6 inches long and made of something like polar fleece with a small opening only at one end.

Can't find reference to anything like this anywhere so just trying to confirm if its something that has slipped in and got jammed or whether this is a microfilter from further up the pipe that has come loose and jammed the pump. The other end of the pipe is connected with a clip held in place by a large hex head screw that I don't have a bit for. Just wanted to check before I go out and buy one.

I've never heard of anything like this nor come across anything like that, are you sure it's not part of something that's been washed? Anything like that would just rot and smell inside a washing machine.
