Anyone know about washing machines? Fluff problem

[Scuzi]

I've noticed recently that when I wash anything in the washing machine that it comes out covered it small bits of white fluff. It's much more noticeable on the darker garments and is a pain in the rear because it's an absolute nightmare to get out.
I'm assuming there's some sort of filter or something that might need cleaning/changing, am I right? If so how do I go about it or what can I do to get rid of this fluff? I can't find the manual so I'm a bit stuck.

It's a Hotpoint First Edition Washer Dryer 1100 if that's any help.

There's no flaps of any sort on the front, just the drawer where the powder and other stuff goes.
I put some of those Bounce sheets in when I dry stuff but I doubt it's those causing it. Probably something the previous tenant put through it.

Fluffy food isn't a problem yet but if I leave it any longer I'll be a fluffy man and may develop a thing for fluffy food.

EDIT: I've just downloaded the manual and there isn't any accessable filters which can be cleaned Am I stuck with fluffy clothes?

GAH!
