HI my boiler
optima 901 pressure is high 2.8 bar+ and operating the prv.I have set the pressure with the heating off to 1 bar to try and stop high pressure but it still goes high. It seems that the burner may be staying on too long as the pressure stays level when burners is.
I have taken the cover of the boiler but cannot find the expansion vessel? any ideas where it is?

How can i check the expansion vessel,or charge it ?

either needs charging or split

if you turn your boiler off and pressure falls to about 1 bar and turn your boiler on and pressure rises to nearly 3 bar your exspanssion vessel is faulty. ever needs charging or its split inside.
