Stainless Steel Washing Machine Hoses
I was about to answer that these stainless steel-wrapped hoses are more reliable than plain rubber, but after looking at some articles on line, I'm not so inclined to say so. This PDF  says they're no more reliable nor last longer than good quality rubber hoses, and another article here says about the same thing. Both rubber and stainless steel clad hoses should be replaced at the same interval, about three - five years.I would still go with the stainless steel hoses, as they're not too expensive and during their lifetime are less prone to damage. However, if your water supplier uses chloramine (as opposed to chlorine) to disinfect your water, then I strongly recommend using good quality rubber hoses and replacing them every three years.
