Our Bosch dishwasher just stopped dead. When we try to turn it on, the "active" light lights, then it makes a very low hum, then the "clean" light lights after about 20 seconds. The washer does not fill with water nor cycle. I have tried the reset, no change. Water is on. I emptied the water from inside under the screen, still nothing. I have shaken it, as I understand that the float might be stuck. Nothing.

Any ideas? My wife is desperate. Thanks.
