About two weeks ago, I noticed my dishwasher wasnt getting dishes cleaned. I usually run it about 2x a week. I bought one of those dishwasher cleaners, ran it through, but still the dishes weren't getting cleaned. I looked inside the dishwasher and claned out the filter at the bottom of the dishwasher. Also bought a different brand of dishwasher cleaner and ran it through the dishwasher. Ran a load of dishs last night and its still not getting the dishes cleaned and is leaving a white film on the dishes. Any suggestions on how to get the dishwasher to clean dishes properly/stop leaving the film besides just washing the dishes by hand?
