I can say that the lower arm, when spraying upward, doesn't quite reach the top rack but for all I know this is normal. I don't know what water pressure I should have so I don't know if it's weaker than it should be. In sort, I believe I have ruled out any clogging problems and I feel the arms are very clean and clear. Each time I have placed lightly soiled cups in the four corners of the top rack and they never get hit with water. All my experimenting has been done in the first 5 minutes of the cycle so I don't know if pressure changes later on, but I do know it's not spinning. Using a fernco (rubber cap with hoseclamp) I have capped the lower outlet for the lower arm (theoretically) diverting all the water pressure up to the top arm and still, it won't spin. I have pushed the top rack back during operation to assure there is a good seal against the back water output, but no improvement.

However, it does move freely with a little push. The upper arm sprays water from all the little holes, but won't spin. The lower arm seems to run normally, spinning and spraying water. I have jimmied the door mechanism so that I can watch it run with door open. I've cleaned the filters and removable arms with vinegar including disassembling the upper arm and cleaning the rubber 2-hole filter. I have checked for clogs and run vinegar through the machine. Recently the upper arm has stopped spinning. I use city water and I would say it's harder than average. Hi, I've owned a Bosch Dishwasher for about 3 years which I've run almost daily.
