Hi Charles,
Don't know about washer or ice maker, but I have an ice maker in fridge . I don't drink the water from hose so I don't use the ice maker. I use a portable ice maker with bottled water. I get the 5 gal. at publixs. It works great. I sit in on my dash out of the way. You do have to transfer the ice and it can stick together, but I always have ice with clean water.
