I have a Potterton 80 Combi.
Hot water works fine, problem is CH.
When on Constant boiler Heats up for about 30 secs then flame goes out. If it happens to stay on will heat all the rads as normal. If switched from CH, either to timed or after using hot water, problem arises again.
Engineer came out and replaced motor but same thing happening.
He seems to think now that it could be the diverter valve or something.
Has anyone else had this problem.
If I haven't included all details I'm sorry but was trying to keep it as brief as possible.
Thanks in advance
