what does he say is wrong with it ?
or is he not 'qualified' to give an opinion ?

It may just be air in the system!
Is the AAV at top left working with the screw just loose?
The person who moved it should identify and fix the problem!
You could check the pump is free to turn and does not have air in it. Thats probably the cause of the problem.
Get back on to him!

I'm with Tony on this one,but the bloke who moved it has the responsibilty to check it and make sure it works on both modes 
If there's a pump problem you'd expect more trouble on CH than HW.
Does the red light go OUT smartly when you turn the tap off?
Could be just a wire pulled off something.
Ask him to show you which is the water temperature sensor, which is the water overheat thermostat, and exactly which wires from the board to the gas valve turn the gas down if the water's getting too hot.
If he does, the problem could just be something like a bad connection on the circuit board which didn't like being disturbed. Those boards are awful for that sort of thing so it wouldn't be his fault. Old boilers don't respond well to being moved.

If he doesn't know what's wrong with it how does he know he didn't do it?

thanks chris, red light goes out straight away after shuting hot tap down...spoke to installer he came and looked at it but no joy said didnt get involved with boiler breakdowns but said in might be dhw microswitch...

so you have to fix it, probably his error at your expense, why not call ln some one in and ger it fixed and send the firt bloke the bill?
or tell him thats what you intend to do can he recomend some one (who he will pay for)

Personally I'd never move a boiler unless fiiting brand new one. It's always problematic and by the end of it it'd have been cheaper (and more cost effective long term) to buy new.
This demonstrates the wisedom of getting a competent person to do this kind of work!
He may be able to physically move it and connect the pipes but whats the point if he cannot get it to work in the new location.
There are too many people doing jobs like this without the necessary skills to follow it through.
There is as much work moving a boiler as fitting a new one apart from cleaning the system. When people call me and I say it will be £500 they say they expected it would be about £100 at the most! As this poster has discovered there is more to it than just a bit of pipework!

does the flow rate start of a dribble then increase significantly after a few seconds, no increase in flow would point towards a wax capsule failure, overheating and shutdown - although a restriction in the pipework would have a similar affect
