I feel your frustration. We've been in our new house for 3.5 years and the dishwasher has been crap for let's see... ummm... 3,5 years!!! SO annoying! We had a tech come an d look at it twice too as we thought that surely there was something else wrong. Turns out that powder is the best detergent to use not liquid or the tablets. Rinse dishes before putting them in, clean filter often and the little holes that the water comes out of on the spinny thingos and do those deep clean thingos that you run without any dishes in there. We do all this and the dishwasher only lasts about a week before we are both cursing it again. Goodluck.
