Etay for Model Number shx45p05uc/64 I have a dishwasher which is not washing well. The upper arm gets water, but not enough to spin and the bottom one spins but barely cleans anything. I took the unit out and ran it without filter in the sump to make sure the sump fills up to the top level, which it does. I also made sure the pump actually turns when the unit runs by visually looking at it when it runs from the back of the unit, (I can see the fins running). I then went on to disconnect the sump assembly and removed the circulation pump (with impeller assembly) from the main sump so I can inspect it. The pump is not seized and I can move the impeller freely with my finger. It does not feel like there are bad bearings or anything holding the motor back from spinning and I did not see any blockages in the intake piping. At this stage I am wondering if I should just order a replacement pump and hope that fixes the issue or if I possibly missed something? Thanks
Answer Hello Etay, You should not just look for clogs and restrictions but also for any point that can cause a loss of water pressure. This causes the water pressure to be low and a poor wash result. Check the spray arm assemblies for separations and the point where the middle spray arm couples at the rear of the upper rack to the feed tube in the rear of the unit. Read More...
