That blinking light is trying to tell you that there is something wrong with the dishwasher. You need to fix the problem or else that blinking light will come back. And the number of times it blinks (before it pauses and repeats) will tell you (or a technician) what is wrong. How many times does it blink?

May have a bad heater. press hi temp, air dry,hi temp, air dry (or whatever button is equivalent on your model). this starts a test and will allow unit to work again. When drying light goes out touch the heater. If it is cold then it may be bad. You will need a voltmeter to tell for sure however.

Try turning off the power to the dishwasher at the circuit breaker box. leave the power off for 5 10 mins and then turn breaker back on and try to restart dishwasher. This may reset the board and it may work

I suspect for either of these units that the timer control boards are bad.

It says in the manual to check the heating element.

push cancel or start resume the green clean light will blink after every wash cycle to tell you the dishes are clean on some you just open the door to clear it on some you push stop or cancel

I just read this for the same problem: push sanitize, then heat and dry, sanitize, heat and dry, sanitize, heat and dry, cancel, then open and close the door. It worked. The dishwasher is running correctly even as I type this. 

I had the same problem when I bought it and it just happened again; the problem is solved by ressting the control panel: Hi Temp ---> Heated Dry two or three times. It kind of goes into a testing cycle and the clean blinking light goes off.

close the door and to cancel that just press hi temp and hetaer dry again hi temp and heater dry and all the lights is gonna light up, it getting into test mode.
After that press cancel
Now get somebody to replace the thermistor of your machine
