Dishwasher is about 4 months old and is smelling a bit foisty. We clean it regularly, including the filter but I've noticed a smell this last week or so. I also ran an empty wash with soda crystals instead of tablets, but it hasn't seemed to help.I don't want to use one of those lemon freshener things, because I find they just add a fake lemon scent on top of the foist and I swear I can taste it on my cup afterwards.
Any hints or tips? It's our first dishwasher so we could be missing something very obvious.
