GE dishwasher, model GSD2000G00WW. Dishes not getting clean or wet. Opened door slightly, noticed lower spin arm not spinning, and the center "cone" just spitting water intermittently. Impeller making quite a bit of noise. I have disassembled pump,motor, and sump. Everything seems in working order, but why is there not nough force to lift that center "cone"sprayer and spin the arms?
Update. I just added more water as the unti was running, and the arms and everything spin fine??? Not enough water coming into the unit?
