my boiler is working fine for DHW but CH is not staying on for more than a few seconds. I see the temperature rise to 72C, well above the 40C requested, then it stops.
Firstly, its not shown me any error codes, and the Bar is correct and not flashing, but when I hold down Mode I can see what appears to be a log, with 4 entries of F22 (temp rise too quickly / low pressure) .. now whether this is from a while back, i.e. before I bled the radiators or not I dont know, but F22 does tally with the temp rise and scarily suggests a blockage / dead diverter valave!
Id like to reset the log, so I can be sure its not an old message, but even when I hold down reset, the F22s are still there.
I am insanely broke at the moment so really dont want to go on a goose chase replacing parts on a 2 / 3 year old boiler and finding its not solving the problem, so any suggestions, such as being able to fire the boiler without using the wireless control (to be sure its not just a problem with that!) before I call someone out would be a life-saver right now!
Thaanks!!
