1) I have had the dishwasher fro 7 years now. It has never really dried the dishes but over the past year, has gotten much worse. Considering a new one but if there is something I can do, that would be great. Right now not liking Whirlpool brand anymore. 2) My tub stinks! The smell is getting worse. Where is a filter I can change or something to clean out to get rid of the foul odor? Thank you,
