Winterizing dishwasher and washer/dryer combo?

Thanks jtfcons and BB_TX! Will do.

You can blow out those lines by running first with cold water setting then with hot. But afterward you need pour antifreeze in the tub and run again so it will pump the antifreeze into the drain trap.

I'm with you on this one. What I do with washer/dryer is hook up the air line as you are already doing and run the unit through a cycle. I select warm/warm water temp to insure both water lines are involved. I hear air flowing when the cycle is going. I also pour a cup or so of AF in the tub to protect the pump before starting the cycle. It's worked for me for 10+ years. I don't have a dishwasher but the principle is the same I think.

Rv anrifreeze. Pump it thru the lines, then start a cycle in each. Once the tub has pink stuff, you can cancel the cycle. In the spring you can pump fresh water thru the system and you will be ready to go.
