First the filter every 5 to 10 cycles? Wow that's pretty frequent.

Manual page 18 same manual?

Thanks practigal. Ours is a different model/manual (page 24-25), but the one you linked at least makes me think that the "filter cloth" may be the lint trap. Still no info on how plugged up the sponge filter can get before I throw it it out and use a replacement, and I'm wondering what people in the real world do. Now to search for U.S. sites for replacement filters for when my first three are gone.

Sounds to me as if the filter cloth is part of the filter housing (frame) where the sponge is.

Sadly, that would not be the first time that I found an answer to something in a manual for a product that wasn't the one I was inter sted in. I really think these manuals should be vetted as part of the product development process

Hi there, I just got this dryer and started using it a few days ago. I'm wondering if the OP or anyone else has an answer as to how to clean that secondary filter well, esp without having to wash it every time, and the original question of how often it needs to be replaced? Any advice greatly appreciated!

Kathy-- I see that the link to the sponge filters I've bought before says they're out of stock. I hope that isn't a permanent thing! Vacuuming is still working well though. I use the narrow nozzle attachment, and if you stretch the filter this way and that while vacuuming it seems to get almost everything out.

I'm curious if anyone else has had the issue I'm having with my Blomberg ventless dryer. For some reason, lint gets past both filters and gathers on the evaporator. It's impossible to clean, because the link is wet and sticks to the evaporator. I bought a special tool to clean it, but the fins are easily damaged, and it only cleans so much of the lint. (I have photos, but for some reason am unable to post.)

Blomberg has done pretty much nothing for me, telling me they've never heard of the problem and that my dryer is out of warranty (this was 2.5 years ago). They did finally send a repair person at their cost, who could find no reason this was happening. I talked to the rep while the repair person was at my house; we spent about 20 minutes on the phone going over every possibility. He ended up sending me a new filter (the one that goes in front of the drum) and after that refused to answer my texts.

The result of all of this is that there is wet lint inside my evaporator and it stinks in a way similar to cat pee. I have to run the dryer empty for an hour after every load to sort of dry it out or my entire laundry room will smell. Bath towels dried in the dryer also smell reminiscent of cat pee when they're wet.

Blomberg has done nothing for me beyond this, and if I want a decent (not cat pee smelling) dryer, I will have to buy an entire new set because I only have room for stacking.

Hugely disappointed in Blomberg service. You'd think they'd want to know why I had this issue, and even take back the somehow bizarrely defective dryer and give me one that works.

This thread may be helpful. We don't seem to get lint on the fins but did have an odor for awhile.
