My dishwasher at cycle start will run drain motor, fill, and then follows with hums and clicks...I believe that to be heater heating, Then nothing. If you open door and shut, circulation pump will try to run for a second or two. No error codes when running bosch troubleshooting guide, although I could not get "audible beep" to occur. With remaining water, washer will drain when selecting the "rinse drain" buttons. Motor does sound a little cluncky but that may be because the cover is off and it is louder. It is clear of all obstructions when removing the impeller cover (light blue colored impeller).

So I am guessing that I have a bad circulation pump that shuts down the normal washing cycle??? I need to get this fixed before XMAS company arrives! ANY ADVICE?
