We had a problem with our washing machine backing up into our Whirlpool dishwasher. After bailing out the dishwasher, cleaning the filters and running a kettle-full of hot water through the drain cycle, I tried to run the rinse cyle and got a 6-flash error code. This indicates an intake problem. I couldn't figure out why.
Finally, I turned off the flow to the intake, unscrewed the intake hose from the body of the dishwasher and got a spray of water in my face from the pressure being released. I resttached the hose, turned on the water, ran the rinse cycle and -- voil? -- no more error! Apparently, something had gotten stuck closed and the pressure relief freed it up. I hope this helps someone. Cheers!
I had the same problem with a Whirlpool ADP 6515, led flashes 6 times, pause and repeat.
Open the door, remove the 2 screws that hold the control panel (1 top left, 1 top right). Gently lift the control panel up and away from the door to reveal the wiring, controllers etc. My controller was a Flextronics UCB-IC-EBL-P7-M3-HE1. Look at the connectors, one of them is marked on the controller as NTC and has 2 blue wires, push down on the white plastic tab below it and disconnect it (pull it horizontally away from the controller)..
I used a multimeter on 200k range and measured the resistance by probing those 2 blue wires and the NTC temperature sensor measured about 50k ohms +/- 5k depending on the room temperature. And that is correct for that NTC. (I knew the NTC was good as I had removed it from underneath the machine previously and measured the resistance whilst holding it under the hot tap as it went from cold water to hot. It's a Negative Temperature Coefficient sensor so the resistance reduces as it gets hotter).
So problem was definitely not that.
Solution was simple, on the connector itself, just use a very small flat bladed watchmakers type screwdriver to clean the pin contact faces and then gently pinch the pins of each wire closer together so that they bites tighter onto the controller.when you reconnect it.
Refit the control panel and problem solved.
Conclusion; the contact resistance of the connector to the controller added to the total resistance of the NTC and made the dishwasher think that the water was below the safe activation of the motor cycle, e.g. it thought the water was iced up.
Job done !

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

If you have strat light flashing, hold start button for 3 seconds- this will reset machine. However, the light flashes to indicate there has been a fault detected- count the number of flashes, this indicates fault

whirlpool dishwasher problem adp 4501 - I had a problem with this machine not starting properly, hunting, with the start light flashing apparently continuously the pump also going on and off in time with the flashing.
After looking around a number of forums I cleaned out the sump gently with a sponge which did not help, then followed this up by pouring a kettle of boiling water into it. This had no immediate effect, but after a few hours the machine started and ran properly again.
Cost no money and saved me the hassle of taking it out and stripping it down - well worth a try.
