I HAVE A BOSCH SHU5305

Question

I HAVE A BOSCH SHU5305 DISHWASHER THAT WHEN IT IS TURNED ON IT WILL NOT DRAW WATER FOR THE WASH. IT JUST SITS THERE AND HUMS. HAD A BIT OF WATER FROM THE SINK BACK UP IN THE DISHWASHER AND SPILL OVER ONTO THE FLOOR YESTERDAY. I CLEANED THE DISHWASHER FILTER WHICH WAS COMPLETELY CLOGGED. I THINK THE DISHWASHER WORKED FINE PRIOR TO THIS INCIDENT BUT THIS COULD ALL BE COINCIDENCE. I DON'T KNOW IF I HAVE A PLUMMING PROBLEM OR A WASHER PROBLEM. THE SINK WATER WORKS FINE. I CHECKED THE ON/OFF WATER VALVE TO THE WASHER AND IT'S ON. IS THERE A RESET ON THIS WASHER? SUGGESTIONS? Jim
