an element is the normal problem when it trips out.could be damp inside the element.run it on gas for few hours and try again. the other thing is that if you have the electric fire on 2000 and then switch the water heater on it can trip out.ours does,not a problem saves me going for the warden.

What wattage is your heater?
60 ohms at 230v is app 880 watts are you measuring the resistance of the heating element?

It's probably caused by a leaky gasket or condensation,it seems that the element is OK you possibly could remove it and reseal it but I'm not familiar with the workings so not sure if that is possible.

i would use it on gas for a week then check again,if it still trips there is a slight possibility water is getting into the element itself.

I had the same problem with my water heater and the testing appeared to defy logic. Everything tested out Ok on multimeter (don't ask about readings - my brother is an electrician and I wasn't sure what he was on about!!), rechecked its function hooked up to a generator and it worked fine. The next time I used it on holiday it just kept tripping. I had a new element fitted and it has been fine since.
I think, if in doubt, stick a new element in.

60ohms across the element is correct but by design you should have near infinite resistance between live/neutral element connections and earth.
So unless the element connections are damp, the element needs replacing
In reality, the RCD trips at 30 milli amps so anything above 20k ohms resistance to earth should not trip the RCD.
However many multimeter's don't read that high and only show open circuit

You will only be able to carry out a satifactory test of the heating element by using a meggar not a multimeter. The difference being the meggar will test the earth resistance and continuity using typically 500 volts whereas the multimeter is "driven by a few volts.
It sounds to me that the element is breaking down under load something which the multimeter cannot provide.
