My Grandparents were snowbirds, and they had terrible luck with washer hoses. They lost one in the summer home in Montana and the fire department called my Dad to report water running out from under all the doors in the house. It had filled the crawl space, and about 6 inches inside the whole house.
After Grandma passed, Grandpa stayed full time in Phoenix. He was selling the large house there for a smaller one, and the house in Montana, and had gone back to take care of matters in Montana right after the contract on the house in Phoenix had come through. While he was gone it happened again, but My dad found it when it was just a puddle on the floor and not through out the house.
Moral, shut the water off to stuff your not going to be using, like the washer, ice maker stuff like that.
