I'm havng an issue with an older (but hardly used) bosch dishwasher. My brother-in-law gave up on it after having it sit brand new for 2 years, finally installing it and having it quit on him after about 10 uses. I now tried it out several years later and here is what happens:

I try and run it and it sounds ok at first. Then it sounds as if it is not filling up with water (although some water came in....the side walls were a little wet from spraying). The float switch activated due to water in the tray.

I took the side panel off to see where it was leaking, and water comes out of three areas (see the attached picture). It seems that water is failing to enter the machine somehow and is backing up (but where?).

Any help troubleshooting this is appreciated. Is it a simple blockage someplace inside the machine? Is it due to the blades not spinning, and therefor not expelling the water as fast as it is supplied? Any chance the pressure is just too high?

-thanks in advance!
