Thank you for your question and I understand your concern.
There is no "reset" button on the dishwasher. Based on your symptom and details I would assume the "thermal fuse" is faulty. The thermal fuse is part #675813 and is fastened to the side of the control board housing. The thermal fuse is in a series circuit between the door switch and control board. Follow the TAN wire connected to the door switch and it will lead you to the thermal fuse. The thermal fuse can be disconnected and tested for continuity with an ohm meter.
NOTE: Disconnect the power supply from the dishwasher before servicing.
The thermal fuse can be ordered from
I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.
