no hotwater or heating working going tob 50 which means there is something faulty

if there is no sign of leakage check the pressure relief pipe (prv) normally terminating outside for any water. If there is water put pressure of boiler to 1 bar turn on heating if the pressure is going to nearly 3 bar the expansion vessel will be flat if the pressure stays between 1 and 2.5 its ok
If there is only water at the prv and pressure is ok you have to reset the valve or renew
if no water is present at prv and pressure is ok you have a leak on your ch system

The water has to be going somewhere - if there is absolutely no leaks in the radiator system or pipes, the likely cause is the heat exchanger inside the boiler is leaking, unfortunately.
