Have whirlpool gold dishwasher made in Mexico, the control lock light stays on, when i push it and hold it just blinks three times and then stays on steady and then does the same over and over, before it did this I noticed the lights for different cycles flashing randomly, and even pushing cancel button once in a while would start the machine up....I have tried to unplug the machine and then plug back in, but nothing is helping....any ideas??

I HAD THIS SAME PROBLEM. TRY PUSHING THIS SEQUENCE OF BUTTONS: HEATED DRY, NORMAL, HEATED DRY, NORMAL. THIS RESET MY PANEL AND IT IS WORKING NORMALLY NOW. I FOUND THIS SUGGESTION ON ANOTHER SITE.

The wash motor has probably froze up.

The appliance repair technician just diagnosed the problem for me. He says it's a bad touchpad, and it would cost $257 for him to replace it. Thought I'd share the diagnosis in case anyone else comes upon this thread.

Had the same problem, removed the kick panel to find a set of instructions under the insulation, had to push a sequence of the panel buttons, its been running great for a couple of weeks now!

Your lint vents in the dryer are clogged.
Your connecting vent on the rear is clogged.
Your through the wall vent is clogged.
Could be any one of these problems or a combination of these.
In any event, you have poor air flow.
