Hello. I have a whirlpool WDTA50SAKZ0 dishwasher that stopped working midcycle. It had no lights on the control panel and pushing buttons didnt do anything. I turned on and off the circuit breaker, no effect. I opened the dishwasher front to look for a thermal fuse, couldn't find one, so I closed it back up. Now all the lights are on on the control panel, every single light including the display, but the buttons still do not work. Any advice please? It's 16 months old. thank you very much!

Update: I cut the breaker and left if off over night. I turned the breaker back on this morning and its back to completely dead again. No lights on the control panel. Thank you for any advice.

I'm attaching your tech. data sheet below. Check the main control board LED light and see if its flashing or STEADY OFF or STEADY ON.

Here's the main control board for your model: Main Control Board W11462458

Thank you, Jake. It is blinking, the light on the main control board is blinking. It's a slow steady blink, does not appear to be a fast blink or a double or triple blink.

Ok good--->LED Slow Blinking: Normal ACU Operation. No unrecoverable ACU failures recorded. LED blinks 0.5 s ON / 0.5 s OFF
