Re: Opening and closing the door on a diswasher damages it
Not rubbish I’m afraid.
However, whilst it isn’t a particularly common issue these days it’s certainly not unheard of.
Under normal use as you describe it shouldn’t be too much of an issue however the normal advice that we offer stands because of things like this, don’t put it on and leave it unattended in an empty home or go to bed with it on. The reason is that if it does break the wiring it can pop the circuit breaker if you have RCDs or, in extreme and very rare occasions it can smoke or ignite the wiring. I stress, this is extremely rare but it has been known to happen.
