Appliance experts: Tell me, am I worrying for nothing?
Several years ago, my sorority sister's home burned down while she and her husband were at work. She said the dishwasher had been left running and it somehow started an electrical fire.
Since then, I try not to leave appliances like DW, washer or dryer running when I leave the house. I also don't leave during the oven self-clean cycle. Now that we have a dog, I particularly don't leave them on when the dog is home alone. This is very limiting, especially since, as is mentioned in a recent thread, DW's take absolutely forever to run.
So am I being justifiably cautious or is there no significant danger, and my friend's accident was a fluke?
