Just come back from a call out, intermittent heating and hot water.
Boiler was serviced (not by me I may add) a few weeks ago.
On arrival you could here the boiler struggling to stay lit on low flame, and go to reset after ramping up to try and stay lit.
Checked the ratio with FGA, well out. Managed to get it sorted on low (service mode) but on high it went off the scale, FGA not happy.
Anyway, I phoned Worcester technical to get the reset settings for the prettl bosch gas valve, the older type with the large air adjustment in the combustion chamber but no one could give me it. I have had to get it once before as had a similar issue before but it took 4 attempts speaking to different people to get an answer. I hate these valves, always seem to have problems getting them back anywhere near requirements.
need to go back in the morning and was hoping not to waste half the day on the phone to technical, any one here know it?
Cheers, Sam
