I have one k machine that all the sudden decides to not turn off by itself after heat disinfection. I've checked in the service mode if the yes box is checked where it says turn off after heat disinfect. but it doesnt. It will get down to 1 sec, then freeze and alarm. anyone else have this problem??

Had that problem before and it was the Power Logic Board

On one occasion I have had this happen and after I re-seated the functional board the problem dissapeared. Try this.

That may be a failed IC 9 chip on the power logic board. If someone reversed the 9 volt battery in the holder, it may have caused the problem. And on some K machines that chip is soldered on, and on others it is socketed and easily replacable. Check with Tech Support for the part number for that chip, I am not sure that it is the same as an H machine part.

was the problem solved for this situation?

wow bringing one back from the grave. haha.. yes it was the power logic board..
