Thats what I was planning to do but was hoping there was another way to go about it then pumping however many gallons of antifreeze into the washer to get it into the drain cycle
A. It doesn't take many gallons of AF to winterize a washer.
B. Try using a mirror to look on the back panel for the model/serial number
C. Go online and find the manual for it.
D. Air pressure alone will not winterize it. You have to have it running and pump AF into it (per instructions).
E. Failure to properly winterize it may result in the photo.
I realized I had screwed it up when I observed water dripping off the king pin while the machine was running. And I didn't have a drain pan under it. Now I do.
