Our dishwasher has been acting up lately. One day, it works fine. The next day, about halfway through doing whatever it does (all the while making a sound like a 737 taking off), it goes silent, offering nothing by way of explanation beyond the “clean” light flashing endlessly off and on.
I know nothing about dishwashers, but I do know about the Internet. And the Internet said the flashing light means the dishwasher thinks the water isn’t hot enough. So it quits.
The water is plenty hot. The dishwasher is being a diva.
