All of a sudden, no power. will not start, no warning.

Before looking into your built-in dishwasher as the problem, check your main electrical panel to see if you have tripped a circuit breaker. If not, you may have tripped a GFI receptacle located on or around your kitchen counter.  If so, reset it! Then try the dishwasher. However, if this IS the problem, this may become an ongoing problem. I agree with (and its code) having a GFI breaker in your kitchen.  But what I don't agree with is when the contractor/electrician who installed this, didn't take into consideration that when these GFI's are put in series with other receptacles (for added protection) in the kitchen, they trip more easily when plugged in with certain appliances because of the motors (eg. refrigerators, dishwashers, etc.) in them. The GFI's sole purpose is for protecting you around the sink where there's running water. It trips on milliamps so you won't get electrocuted around the sink. Also, if you have other appliances running at the same time the dishwasher's running, makes them more susceptible to trip. So in conclusion, first check for power. Second, check for GFI breaker (or vice versa). I believe you should find your problem here. If so, reset it and wait to see how and when this does it again. GFI breaker's are sensitive breakers. They tend to wear out before a regular outlet (receptacle) does. Not knowing how long and old this (GFI) receptacle is, I'd replace that if it happens more frequently. This usually does the trick. I hope it's not your built-in dishwasher. If so, feel free to contact me again, and I'll help you with that too. Good Luck with this, and I hope you get everything back in working order. Take care, Jim
