turns out you were correct - sort of. It made me check a few things and turns out all of the return valves on each radiator was closed. The rads had been removed for decorating 6 months or more back and this detail was forgotten. With no other bypass valve out there, no return path for any of...

Will check and make sure I am not doing something stupid there. But pretty sure they are open as the cold water feed is the same valve on it and that works ok for filling the boiler and the hot water then flows. Even tried the heating valve at a 50 / 50 setting just in case - a tip from a...

thanks for replying. Had the the front cap off the pump and the thing is spinning for sure with plenty of force. How would I check for either of those things? And then what to do about them? The pump air bleed valve does sound like it releases air when the system is refilled. But is it working...

proud owner of a saunier duval f24e therma classic ;-). That does not want to work with the central heating but the hot water is fine after it was refilled. [heating system was drained for decorating] (advice for these boilers is to replace - and I could not agree more - but we have already...

thanks for the warning !!!

it is fixed - replacing the main control board with another, "as new" board for a reasonable price. The original version was hard to come buy but replaced with a newer universal S104700 "SYMSI 7.0" which I could find over here at a reasonable price approx £100 Super chuffed, and thanks for...

Unfortunately not really able to swap it out at the moment. Can see saunier duvals are problematic. And from the bits I've replaced over the years I'd say that's a well earnt reputation... ...timer, diverter valve, non return valve, refill valve. If we crack this problem then it might help...

Thanks for the replies. Understand an engineer brings the experience to know the likely culprit and maybe diag tools or hook up to the board to see what is going on. Would like to avoid the expense for now. But let's see how the trouble shooting develops. Boiler is 18yrs old so could be...

Hi central heating is fine but when the boiler is cold the hot water isn't working well. Boiler cuting out every few seconds. After about 5 minutes of this all is well and works normally. Any ideas which part might be at fault here? Saunier Duval - thermaclassicr f24e Combi. Many thanks A
