I have a one-lever shut off valve for my washing machine. I plan to
get some SS braided hoses, right now I have rubber ones.
Anyway, I want to start using the shut off valve each and every time I
am not using the washer. Maybe a stupid question, but has anyone had
any problems while doing this? Like, the valve leaks or will wear out
Thanks in advance, John

That is its purpose. You'd better start doing it always NOW and save
doing it sometimes for when you have the steel hoses. (You should do
it always then too, but my point is you have your plans backwards)
Going back (way back) to my mother's time, the one-lever shutoff valves have
lasted about 20 years.
Besides the obvious hose-burst that may occur by leaving the valves on, there's
an additional reason for shutting them off when not in use:
The water pressure, over time, deforms the mixing valve in the machine,
eventually causing the solenoids to stick open or closed, resulting in either no
water delivery or no temperature selection.
When you shut the valve off what do you think happens to the water pressure
that's trapped between the S/O valve and the machine solenoids (aka,
hydraulic lock)? Unless there is a way for this pressure to bleed down it
will remain high and will remain the same (or near) as the supply pressure.
Disaster prevention is the best reason for keeping the shutoff valve closed
except when the machine is in use.
I thought I missed something...but I agree with your thoughts.
OTOH I've never had a hose disaster in 25+ years...just lucky I guess,
but then again, I replace the supply hoses fairly regularly (5 years
or so) and have never shut the supply off other than for maintenance.
The main water line. There is pressure either from the well or city line,
in the piping at all times. If you close valves located midway in the
pipes, the pressure remains constant. In the case of a washing machine
hose, if the hose were to break with the valve closed, the only leak is what
water happened to be in the line.
Think of one of those long balloons, cut the end off and pinch it
(washing machine valve), now blow into the balloon from the other
end until you have a pressure equivalent to your water pressure.
Pinch off that end (shut off valve). What happens to the air in the
balloon? Its still at pressure isn't it? If you want to relieve the
pressure, then you have to open the unpressurized end. The only way
to do that is to either unscrew the fitting at the machine and deal
with the drip, or cycle the machine through a fill cycle - the only
water it will get is what's in the hose.
Closing the supply valves to the washing machine, when the machine is
not in use, is cheap insurance against a flood caused by a failed
hose. However the steel wrapped hoses can still fail since the line
pressure is held 100% by the rubber.When I replaced my rubber hoses
with steel wrapped ones I was told that they offered no increased
