Yes I have the instruction book and it makes no mention of a fluff filter. I know what you mean though, our previous washer dryer had one at the rear.
It looks like I'll have to open it up and investigate - it may be easy once I get the back off. Certainly it was incredibly simple to replace...
My Zanussi Washer/Dryer is filling with smoke after about 5 minutes on the dryer cycle. Illogically it seems worse if it follows a 900 spin rather than a full speed one.
I haven't opened up the machine to investigate yet but would appreciate advice on what to look for.
