This might seem like an odd observation, but here goes.
I have one of the new front loading washing machines,
and they are supposed to use a lot less water than a
conventional washer. If I want to do a hot water wash,
will the hot water actually reach the washing machine by
the time it quits taking water? Approximately how far
away, using lets say 1/2 line, will you not get hot water?
just a thought
