Maytag had a thermostatic water valve (part# 204436) for '06-First gen LAT models that would increase cold water temps to...if I remember correctly...75F. As far as I'm concerned, this should have been standard equipment in all washers by the late 1950's. It would be the end of poor cleaning results due to cold water and would provide solid warm temps as well. In todays realm of cold water washing, it would greatly help prevent buildup in the outer tub and keep the machine much cleaner and reduce unnecessary repair calls. I would personally increase those temps to 85F but 75F is still a big improvement over frigid water temps during the winter in most places.
