My dishwasher is having some problems. The rotator arm doesn't move and for some origin there is also no hose being splashed around. The dishwasher is probably 2-3 yrs ripened. It has be working fine before, don't suppose the water is cut from trailing. The dishwasher does make a sort of grinding hullabaloo (which was also at hand when it worked fine). Only issue appears to be water not one there to clean up the dishes.

Anyone experience this too and what did you do?
thanks
Answers:    The arm is moved by the hose flowing through it. It sounds like the pump may hold failed or its inlet may be plugged. I enjoy had angelic luck troubleshooting appliances at this site:

If the pump is belt driven , the belt has probably broken
