When ednoria stayed over a few nights ago I told her about my wonderfully quiet dishwasher. Unfortunately it seems that this particular appliance is sensitive to praise. Now it is dreadfully quiet. I called Sears but they were not inclined to diagnose my problem over the phone. Googling was more productive. Well, I established a hypothesis at any rate. When my new thermal fuse arrives I will let you know if it does the trick. Or not.
