I have a foul stale smell in my new dishwasher, in spite of the the things they tell you to do. I have also had the engineer out and they say nothing wrong. I am sure it is to do with the filter. My old dishwasher filter always had lots to clean out, this one always, every time I check, has none. Comments please
I am not an expert. But, dealing with things that smell stale (mold?, bacteria?, other?) there's a short laundry list of things I'd try.
- CLR (Calcium, lime, rust removal) Does wonders for a lot of things.
- Vinegar and salt - The vinegar is acidic in nature and kills lots of things. The salt is also violently brutal to other things that are unbothered by acid.
I did say it was a short list.
As an aside, most laundromats will keep the doors to the machines open. This is done, even if only cracked open a bit, so the machine can "breathe" the water out, thus helping to prohibit growth. If there is a way to chalk the door open, just a bit, to help the machine breathe, I think it might help regardless of the others.
