I started the dishwasher and when it started to rinse I lost all power. have checked circuit and wall plug I took the dishwasher out and checked all the wires. Even the lights on the control panel are not lighting up 
as usual I will be happy for help from this great site:D Thanks!!!
Probaly a blown thermal fuse located as a plug in on the right side of the electronic module behind the panel. Part # AP3178588 This blows sometimes if the water temperature is well below 110 degrees and/ or there is a power surge at a bad time in the cycle.
It can also blow on a heater/thermostat failure. Unit should be checked with an amprobe, combined heater/motor current typically less than 9 amps.
