Dishwasher - top rack no water pressure
I don't have a Model # for this is a portable dishwasher (Frigidaire Ultra Quiet III) that I am wanting to buy out of the newspaper. It features delayed start, pot scrubber, normal and light wash, extra water heat, etc.
I would think that the question regarding the basic function of how the water pressure reaches the top rack is generic to all dishwashers. None of the jets are clogged and water pressure to the lower rack is strong, but the amount of water coming out of the top to feed the top sprayer arm is just a trickle. I know this because when I open the door I can see that the sprayer arm had not moved. Then I put a glass upright on the top shelf to see how much water is coming out of the top port and after several minutes the glass only has about an inch of water in it, when it should be overflowing. Certainly not enough water or pressure to cause the top sprayer arm to rotate.
So would this be a water intake valve problem, a pump problem, or a possible clog somewhere between the pump and the top port?
