I'm currently in the process of building a device which will shut off
the power to a washing machine in the event of a hose failing and
spewing water out all over the floor. This is an eventuality which has
always caused me considerable angst, so I finally decided to do
something about it. After all, those flimsy 'exhaust' hoses go brittle
over time and having one split 'in action' could cause a significant
amount of damage to the surrounding area in a very short time. Having
something to cut the power off instantly as soon as the water hits the
floor would be a very worthwhile addition to the utility room and
beyond.
I came up with a pretty simple design which I've already proven to
work first time at the breadboarding stage. However, turning this
concept into a practical proposition is taking *far* longer than I'd
imagined. I am getting there, but *slowly* and was wondering whether
other people here have the same sort of problem as I invariably do
with these little personal projects they undertake?

Tell us about your design.

I recall a water detector made from a clothespin and an aspirin and a
couple of pieces of wire.

But it doesn't take much current to turn on a mosfet.
