My instruction book says pour a quart of RV anti-freeze in the washer and run the drain cycle BUT only the washer pump and drain hose and hopefully the P-trap is winterized..
I like to winterize the whole system. I first run the washer on warm water wash until I have run 1-2 quarts of anti-freeze, I stop the fill cycle and go to drain cycle. After the Drain cycle ends, I then run the fill and drain cycle again using a quart of RV antii-freeze.
When to going back to be normal operations, there is no hoses to connect. My wife can flush as soon as I turn the water on.
