What is the best way to winterize a standard large capacity washing machine?

Turn off the water at the cold and hot taps. Disconnect the hoses from the taps and the washer and drain them. Lay the drain hose flat on the floor to drain it to a container. With the hoses disconnected and the drain hose flat, start the fill cycle (set to WARM) briefly (15 seconds) to open the inlet solenoid valves and allow water to drain from them. Start the rinse cycle to pump any residual water out of the tub and drain (15 seconds).

Turn off water and disconnect inlet hoses as described above. Pour 1 gallon of RV anti-freeze (for potable water systems) into the tub. Start the rinse cycle just enough to start the drain so antifreeze goes through pump and into drain hose. Before using the washer again, run a small rinse through to flush out the anti-freeze.

If the product will be exposed to sub-freezing temperatures, turn off the water supply to washer, disconnect fill hoses, drain them and reconnect. Remove the drain hose from the standpipe in the wall and place it into a shallow pan at floor level untill the water floe stops. Unplug unit and you are good to go.

If no sub-freezing temps are expected, turn off water supply. Turn on washer for a warm wash cycle for a few seconds to relieve the pressure in the hoses. Turn off machine and unplug it.
