Don for Model Number SHU43C Our dishwasher has just started leaving a white powder like residue(when dry) on mostly plastic dished. We have always used cascade powder, jet dry and public water supply. We have had it about 5 yrs and it has just started this problem. Nothing has changed in the way we use the washer. I have dissasembled the filters down to the impeller and cleaned. Removed the water channels to the top rotor and cleaned. Should the water be heated on all cycles or just at the end? Could this be the problem? We have run vinegar thru as well. Thanks for the help. Don
Answer Hello Don. The water should always be ran hot into the unit and is heated during the cycles. Look for low water levels and replace the valve if needed. Low water level will cause this issue. Read More... Answered by AppliancePartsPros.com | Wednesday, November 27, 2013
