Never overload

Never overload, especially with heavy items (most full size machines max out at 3-4 large bath towels. Never under-load either. In order to be balanced there must be enough material to cover the spin basket all the way around. For example if only one sheet cold be fine because its so large, but one bath towel it can end up lumped on one side and make the machine vibrate and/or bang). If the washer is too full, there’s more rubbing/abrasion on the clothes, which dulls the fabric/colors. So, don’t overload.
