My Kenmore Ultra Wash 665 dishwasher has the "heated dry" light flashing and nothing works. We've tried the sequences mentioned and so far, nothing works. The first thing we did was reset the power at the breaker before we found this site and started trying different sequences. Any suggestions? This is frustrating.

It could be a number of things and they all have to be checked.

Or you can go to the Sears sight Replacement Parts & Accessories | Sears PartsDirect and download a tech sheet by inputting your model number or avail yourself of a chat with a technician.

Got an ohm meter?

The most common reasons are: Shorted heating element, bad control board, and others. See: https://www.youtube.com/watch?v=24C5vID9T3g . I hope this helps.
