Cancel light and rinse only light keep blinking and wont start
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.
