GE Dishwasher upper spray arm does not spray and rotate.
Our GE Profile dishwasher is 5 years old and the upper spray arm seems to have stopped spraying and rotating. The spray arm rotates freely when the washer is off. There is water in the base of the unit and the lower arm seems to be working. What should I look at first? This unit is in a vacation rental in the Caribbean and there are no service men available.
