Here is what I have done so far as winterizing the residential whirlpool.
Down by the drivers side rear wheel, I shut off the water, and unhooked the hose to the fridge, nothing really drain out. then I went to the fridge, put the bail down so it would fill with water, and make ice, made a few ice cubes, then tonight I put a glass by the dispenser, and nothing come out. I then unscrewed the filter in the fridge, replaced it with the bypass plug, and tried to dispense water but nothing come out. I also left the bail down, will check tomorrow if any water/cubes come out. I'm assuming all the water is out of the fridge, and hopefully the solenoid. I don't really want to put rv fluid in the fridge lines. Probably in a few days I will put rv fluid in all the lines and winterize the washer.
