I have a Kenmore Ultra Wash Dishwasher (model 665.1588) that will no longer start. Its roughly 4 years old.

The Cancel/Drain button starts the 2 minute drain cycle, so I know its getting power.
The China/Gentle light is the only cycle light that lights up (but I can't start it either).

I have tried resetting the power breaker for 30 minutes to no avail.

I have checked the overfill float and it moves freely, if I pour water into the bottom it drains the water out properly when I press the Cnacel/Drain button.

Thanks in advance for the help!
