Maytag Quietseries 100

I have a Maytag Quietseries 100 dishwasher. When started it fills with water and then you can hear the washer sounding like it is running but there is no water coming out of the spray arms. I took off the spray arms and ran water through them and they are clear. I ran the washer again with the spray arms removed, the wash motor sounds like it is running, but there is no water coming out where the spray arms were at. Not sure if that means there is a problem with the wash motor or not. If anyone has any suggestions, they would be appreciated.
Thanks
Fred
