The "cancel" light blinks on and off rapidly. If we push start for the cycle the dishwasher clicks off and on intermitently.

Mine blinks if the door has been opened after a cycle has started. I reset the start by pushing the blinking start/cancel light

The Start/Resume light is flashing

This flashing light indicates that your cycle or start-up was interrupted.
Possible causes: The door opened during the cycle, or the power was interrupted.
To resume operation: Make sure the door is closed, and press Start/Resume.

The Clean light is flashing

You should call for service if the Clean light is flashing and the machine is inoperable. It is normal if the Clean light stays on after the cycle is complete. The Clean light is an indication that the dishwasher has been run and that the dishes inside it are clean. Once the door is opened after the cycle is complete, the light will shut off.

The lights are rapidly flashing

Any key that gets stuck will rapidly flash. Press the key a few times in order to release it or press Cancel.

The Rinse Only light is rapidly flashing

If multiple keys are stuck, the Rinse Only light will flash. Press each key, one at a time, to release the stuck keys, or press cancel.

It sounds like he didn't run it completely through try holding the cancel button down for a few secs.

START/RESET status indicator light flashing

You have pressed the indicator light flashing START/RESET pad while the START/RESET dishwasher is running. This will cancel the cycle. The light will stop flashing after the dishwasher drains (about 90 seconds).

• Press the pad once to start the dishwasher. Press the pad a second time when the dishwasher is running only if you wish to cancel the cycle.

Power to the dishwasher was turned off while a cycle was running and power has just been restored to the dishwasher. The blinking lights indicate that the dishwasher is draining the potential water inside.

• The light will stop flashing after the dishwasher drains. A new cycle will start automatically.

Good luck

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

Hello,

Hopefully you have resolved your issue. I have not heard of the cancel light flashing issue. I have had problems with the clean light flashing seven times over and over and the control panel will not operate. Here is the solution to that. Maybe it will work for your issue as well.

Open dishwasher door,
Push Hi Temp Scrub button,
Push Saver Dry button,
Push Hi Temp Scrub button again,
Push Saver Dry button again,
All lights on control panel will come on.
Close dishwasher door,
Push Baked on Cookware or Normal Button.
Dishwasher should start and complete cycle.

It is good if you have kids that play video games. Their fingers are used to pushing buttons quickly. I guess this resets the control board. The service guy let me have this info as I used to deliver appliances and work on them somewhat.Hope this helps.

Good Luck,
Tom

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 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.

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
