My control panel and the plastic harness which leads to every electrical element in the dishwasher is completely burned and yet there was no safety mechanism to prevent this from happening.

Smoke stopped billowing from the unit when the door was opened, thus shutting off the power. For such an expensive stainless steel unit, I would like to know if replacing the control panel and harness is economically feasible. Could there be additional damages beyond what I see (melted controls and soot). Does Kitchen Aid have any responsibility beyond the warranty year?
