The upper spray arm will not turn while dishwasher is on. I have had 3 service call come and they have not fixed right yet could you please help me? thank you kindly cathi
You will want to check to make sure that the check ball under the volute is moving freely as this will be the most likely issue with the upper spray arm not turning. Also check to make sure that there is enough water getting into the unit. Also check to make sure that there is nothing caught in the impeller.
