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