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.

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!

It's a heating issue either a bad heater or bad sensor.
