We have a dishwasher integrated in our IKEA kitchen (went for the middle of the road choice) - have only had it since June, and already it's getting pretty shoddy at cleaning. Everything seems gritty.
Have tried - salt, rinse aid (do these all time), taking apart and cleaning g thoroughly, various dishwasher cleaners, rinsing plates before they go in.
Before I go back to IKEA, is there anything obvious I'm missing?
