The boiler is not leaking or losing pressure in any way.
I have since discovered that the boiler will do its job if i drop the temp of the hot water to 45 degrees. if i raise it to 48 degrees it drops to a low flame. it is a little perplexing.
for your information it is my own boiler at home. I am a gas safe registered

I have checked all of the normal problems. the boiler works ok at 45 degrees. which is ok.
however 45 degrees is a perfect temp for breeding legionnaires disease, so i would like my boiler to push out max temp from time to time just to clean the pipes.
evening mike, sorry for the delay with my reply. i have been out doing the day job.
Boiler runs ok at 45 degrees. at 55 degrees it still goes down to low flame. It also goes to low flame at 48 degrees.
max for boiler is 62 degrees.
