I shut off my combi boiler Worchester 28i Jnr, I bled my radiators today and the air came out and I retightened the valve, I switched on my combi boiler and the pressure on the bar gauge was zero and I got no hot water.
Reading around the iternet I see that my combi boiler has a plastic key underneath with you use to somehow increase the pressure for the boiler, I have decided not to touch it but have called a plumber who is due early tomorrow morning.
What should the plumber actually be doing ? I don't want him to waste time and money farting about conning me out of hours of work.
