I am ready to throw this dishwasher out. Not only does it leave a horrid haze on glasses (probably a hard-water issue, I know) but it seems to have filtering problems--there's grit and particles all over after it's done. The dishes are worse than when I put them in, even if I've rinsed them almost completely clean first. I finally figured out how to pry off the little filter in the door, but cleaning it out is a nightmare--I even took the door liner off, cleaned all the gunk out behind it, etc. It seems there ought to be a disposable filter liner or something like it, but I don't think we have a manual that tells. Anyone have any advice before I give this thing to Goodwill?
