Got a new dishwasher and the instructions utter that after every use I should turn off the sea tap-is this really necessary? The marine tap is located within a tricky spot and so turning it on and off is going to be a hassle.
Answers:    The instructions for wash machines say this too. I bet that not a soul ever turns the water supply rotten in between use! So no, superfluous
Hmm have never ever turned mine bad - and I've had dishwashers for roughly speaking 20 years now!
