There are no legal rules or guidelines about when you can turn on your washing machine. In fact, because electricity is often cheaper on weekends and nights, this is the time for many to do their laundry. However, in some cases, such as apartment complexes, using a washing machine can be a nuisance at night. During the spin cycle, a washing machine can produce quite a bit of noise. There are guidelines and rules about producing noise during the night, but very few washing machines – if they are positioned correctly and used properly – exceed this limit.
