Title: Lower filter stuck
Post by: helvelyn on September 21, 2015, 11:54:54 PM
I am having poor suction on my DC03, especially from the hose. I have checked the hose, cyclone, cassette, and no obstructions or breaks. I'm now checking the filters. The top filter came out with a bit of a struggle - I had to bend the top of the housing upwards a bit, but the lower (post-motor) filter is firmly stuck. I tried pulling it out with the plastic loop, but the loop broke off. I'm reluctant to try pulling it out with pliers for fear of damaging the connection surface. Any ideas what could be causing it to stick, and more importantly how to free it without (too much) damage?

Also the various seals are all in place but some look a bit tired, especially the round flap-valve in the cassette. It is not fully closed by about 3mm when the machine is off, but the vacuum seems to pull it closed when running. Is that normal or should I replace it?

Thanks

Phil

Not sure but does it twist first?

The case twists to get the top filter out.

But the one underneath appears to just pull out.

Its a while since I have done one to be honest. Lets see if anyone else has had one in bits more recently.

Must have been case I was thinking of, wonder if its just stuck with dirt, or perhaps slightly melted if motor has got hot, try rocking it.

Turn the machine upside down, turn the filter and it should fall out :)

Isnít the lower filter a ďlifetimeĒ HEPA whatever that means.
Shouldnt need changing ?

They are a lifetime filter. But I can imagine Dyson didnít envisage them lasting 24 years (they were released in 1997) so if the machine has been well used, the filters are probably a bit past it now!
I would imagine their definition of Lifetime was probably 5-10 years!

Good point - who knows what lifetime means. But you donít seem to list a replacement

If it looks clean I wouldn't bother replacing it. It's an exhaust filter. DC03s were very well filtered.
