What should I do if the washing machine will be stored in freezing temperatures?

Turn off the water supply tap, disconnect hoses and drain the water from them, then add 1 gallon (3.8L) of nontoxic recreational vehicle (RV) antifreeze into an empty wash drum and run a spin cycle for 1 minute. Unplug the electrical cord, dry the drum interior, remove and drain the dispenser drawer, and store the washer upright. After storage, run an empty wash cycle with detergent to remove the antifreeze before use. (Page 23)
