my washing machine smells when its empty, help!!

[ssd]

how can I get rid of the smell, just a damp yuck smell, any suggestions?

I try to leave the washing machine door wide open after i've done a load, so that the leftover water air-dries naturally. I've found if I let the door close to, then it ends up with that damp smell.

Dr beckman do a cleaner that you put through a wash cycle if its particularly bad, and it works well

90 degree wash with biological powder (not liquid/gel). Add a load of vinegar. Leave door open.

i think there's something in the air as mine's really smelly atm, and i'm quite often one of those people who are full of shite tips about using vinegar and bicarb to clean it!

i've done all this, even gone out and bought bio washing powder and done a 95% wash with the machine empty, and it still smells.

i think it's the rubber seal tbh...any other ideas or will i have to have the rubber replaced?

and at 95% wash

The bio powder works but it takess while - maybe a
