Reading post here on winterizing, I realized that I had not put the pink stuff in the lines for the washer. I went out and bought another gallon of pink, got all setup and would not pull anti freeze into the unit. I knew that it worked fine a couple weeks ago. So the troubleshoot began. end of story, pump had air lock at output (I saw this late in the game) so it would not suck nor stop running. I disconnected the output line and let the air out. Works fine now. Had I not been so concerned of wasting antifreeze I would have saved time (I think) if I had simply opened a faucet.
