Hi, new to site looking for help.
I have a 20+ year old kitchenaid kdi-21ad
dishwasher. Installed in new, about 25 years ago. Lately it's developed an problem. The spray nozels do not spin. Water is comming out and the bottom one squirts to the roof of the machine. Not as sure about the top but when I open the door during a wash cycle I see water dripping out. I've juriey rigged the limit switch to watch the unit run, got a little wet in the process, but neither of the nozzels are spinning. They turn by hand nice and easy. I;ve cleaned the filters under the bottom nozzel, was pretty well blocked, but is clear now.
What causes the nozzels to spin?
Why would water come out but not spin???
