The upper spray arm of the dishwasher is evidently not working very well. I am thinking that the water delivery tube or upper nozzle might be clogged up since the lower spray arm seems to work fine. How does the nozzle disconnect from the tube?
ANSWER Hello Richard. The first thing to check is the water level in the unit. If it is low, it will cause the issue you are having with the unit. It should fill to the bottom of the heater. if not, replace the water valve on the unit.
