Dishwasher woes
I can't quite figure out why, but my interest in electronics never translated into any aptitude to tweak home appliances or automobiles, unlike some of my friends. I was never one of those kids who tore apart the toaster to figure out how it worked. It was enough for me that it heated up the bread.
Anyway, our dishwasher stopped working a couple of days ago and a tech came out today to take a look at it. Turned out there was a power surge of some type and the controller board that manages all the system's on-board diagnostics froze up, sticking the dishwasher in an endless loop that I, as a hapless operator, couldn't escape from.
Fortunately, he knew the Vulcan nerve-pinch to reset the system back to its baseline, so he had the machine up and running about ten minutes after he arrived.
I suppose I'm glad it wasn't anything more serious.
