started the wash cycle, stopped, flashed now no lights will come on

I have a barely over 1 year old (just out of warranty of course) Whirlpool Gold model # WDT920SADM and have had trouble with the control panel off and on. Yesterday, it starting the wash cycle, stopped, when I pressed resume it flashed , now no lights will come on at all. I have tried the 123 sequence to reset no luck. I have turned the breaker on and off to try to reset the panel. No luck. Does anyone have the same problem? Whirlpool set up a service call, agreed to pay for parts since it is so new, but we have to pay for the service call and labor. I bought the top of their line dishwasher and am sorely disappointed in this. Thank you for any help you can give me.
