Winterizing Residential Fridge and Clothes Washer Lines

[Skip12]

I have a Sabre 36bhq in case it matters.

I have a couple questions regarding winterization:
It has water lines for a washer and dryer but I've never used them. Do I need to run the pink stuff through them or will draining the low points be sufficient? I ran some pink stuff through them by pointing the outlets at a towel and blasting away but not sure I had to do that.

It has a residential fridge without water (no cold water, no water filter, no ice maker). Do I need to do anything to winterize it?

As always, thanks for the help!

Detailed instructions for winterizing the washing machine should be in the manual. We don't winterize, but AFAIK you want to pour some antifreeze into the drum, start a rinse cycle and let it pump the antifreeze out. The fridge should be good if you don't have water going in.
