Or water inside the pump power connections be careful do it with the power isolated
Unplug burner and try again. Will give you an idea if it's the pump or a burner component.

No water leaking.
Trips when demand for heating comes on from the programmer.
Nothing has changed, just started doing it today
Murdoch, what do you mean by ATM, if you mean at the moment the answer is no the heating is switched off, the domestic hot water is on and running fine, it happens when i switch the heating to on then it trips.
Thanks

I have a grant vortex combi and it keeps tripping the main fuse when the programmer calls for heating.
This has just started, it was working fine before.
Anybody got any thoughts
