Kenmore elite/whirlpool wont run, light blinks steadily

my dishwasher turbo zone light is blinking steadily and the machine wont run. i put it in diagnostic mode and the turbo zone light is still blinking steadily. any suggestions?

See the attachment for the tech sheet.

Have you tried removing power from the unit for a couple minutes to see if it will reset?

Could be a stuck key error.

This could be either the keypad or the control board.

The only way to check it is to check the key outputs.
If they all check out OK then I would replace the control board.
Still a bit of a crap shoot but your odds of replacing the actual bad part are better.
