Whirlpool dish washeri have 3 different blinking light in my whir pool dish washer the light does not stop blinking and the machine does not start

SOURCE: Normal Light Blinking - Dishwasher not working

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.

SOURCE: flashing light

I had this problem at home too, it turned out to be a kink in the water outlet pipe. I straightened out the kink in the pipe, put duct tale around it to strenghten it and the dishwasher has been working perfectly since.

SOURCE: my dishwasher model adp 941 won't start - start led flashes

exactly the same problem today with an AD9520

Don't know the cause but from reading other posts re dishwasher problems I tried holding start but on for 5 - 10 seconds and it seemed to clear the symptoms at least. It ran for a short while and stopped but the flashing had stopped and I could start a wash cycle which is now running!

SOURCE: Blinking Clean light in Whirpool dishwasher

Control is programmed to stop running and not allow any further cycles if it detects a water heating problem (no temperature increase detected in heated Main Wash on 3 consecutive cycles). Control blinks the Clean LED 7 times repeatedly and disables the Start/Resume key until cleared. Running Diagnostics clears the control and allows it to operate again. The water heating problem must be fixed or the control will stop running again. See potential causes below. Heater circuit problem: ■ Open in heater. ■ Open connection or component in heater circuit. ■ Faulty heater drive circuit on control. 1. Check operation of heater in Diagnostics cycle. 2. Unplug dishwasher or disconnect power. 3. Check resistance of heater and all components and connections in the water heating circuit or heat dry circuit.

dont forget to vote hope this helps thank you

SOURCE: My Whirlpool quiet wash plus 940 series is stuck on "lock out"

Same problem and I was about to call for service. Opened the dishwasher to get the model number and noticed a sticker stating to hold down the Heated Dry button for 5 seconds to clear the lock light. Worked for me!
