My powermax 155 boiler is approx 10 years old, recently every couple of hours it loses water pressure and goes on lockout mode which is really frustrating. I am forever refilling the system with water and i am awere that the presure reading should be 1bar to 1.5bar, has anyone got any suggestions on rectifying this problem or is it a complexed job for a engineer to repair.
please help i am at my witts end
