My Bosch Dishwasher SHy56A05UC/14 suddenly has no wash pressure from the circulation pump. When the water is sent to the lower arms, the arm rotates and the water shoots up about 6-8 inches. When the water is sent to the upper arm, the arm does not rotate and water barely comes out.
I was hoping to preemptively order some parts for this before doing the major exploritory dismantle. Stuff I know so far:
• very little pressure/flow from the circulation system.
• Reached into circulation pump inlet and found no blockages
• water heater had been working in the past, not coming on now, but I assume that is from the circulation flow switch not activating do to low flow? Is that true?
My guesses at this point without dismantaling and actualy looking at the thing are:
Missing/broken impeller vanes?
Some kind of blockage between the pump and the outlet. Is it possible to have a blockage there, it seems like it is just the heater module and pretty wide open space.
