It can be really frustrating when appliances like washing machines, refrigerators or stoves just stop working. Before you head to the store to buy a new one or hire a repairman, look for simple solutions. Over time, appliances can slowly shift and move, eventually unplugging themselves. Circuit breakers can also be tripped, so check to make sure you don't need to reset yours. And if the flooring has warped or moved (and the appliance isn't level), some appliances will automatically turn themselves off as a safety precaution.
