Hey lads!

I've recently refurbished my friends Dyson DC25. She got it off eBay for 20 quid, it was in a pretty mint condition, just very dusty. A bit of elbow grease, spit and polish and it looks like brand new, me myself was impressed.

I gave both the pre and post (or A and B) motor filters a good soak and rinse. Dried for over 48 hours (it's been so hot in London I wouldn't be surprised if they dried within minutes to be fair). The pre motor filter works all fine, there's good airflow, good suction, even better than before.

However - I think somethings gone wrong with the exhaust filter. When fitted it makes it sound as if it struggled pushing air through it, and then it pops the filter out (even though it has a latch) stoping the ball from spinning smoothly. It was working fine before I washed it (which now makes me regret touching it in the first place). It just won't work with the filter on, it literally spits it out.

What have I done? (By the way, I did already order a new one)

The filter has had it. They don't last forever and this is a common thing on the DC25. Either use it without the exhaust filter or fit a new one and it will be fine. I'd avoid getting a copy part and go with a genuine replacement part

It makes sense. Like putting your finger over a garden hose, the water is going to find a way out and want to push your finger away if it cannot get through it. Filter has probably packed up and no longer filters, so it's like putting a brick over the opening.

Yeah sure it makes sense! I was just surprised to see that happen. However many vacuum cleaners I've laid my hands on I have never seen anything like that. What surprised me specifically was the fact that it seemed to all work okay before I washed them. Perhaps it was actually filled with some really fine dust that with water just glued the filter in? Who knows!

Thanks for your help guys, I already got her a new filter. Hopefully it won't spit this one out lol!
