That was a question,I was asking what should I do, could I re-solder it or would I need to buy a new PCB. Read the first part of the quote again

Page 4 of manual, item 20-cold water supply cock (inc. automatic flow regulator) No have had PCB out and checked all joints - no problems There I think we have found the problem, the gas flow rate is not as per manufacturer's figures, the gas rate is down by 0.21m*/hr. The gas service pipe...

I always thought that OK meant that some thing was OK, acceptable may have been a better term. I have not measured the flow rate or the temperature, but I do know the difference between hot/cold, time scale would be approx 5 min. How ever you have still not answered my question is the AFR built...

As I said I asked a question regarding the automatic flow regulator, is it built in to the cold water supply cock, or I will add this, is there another AFR some where in the boiler. Yes that is correct but I am now not sure that is the problem, if you remember I did indicate that if the...

I asked a straight forward question "is the automatic flow restrictor built in to the cold water supply cock supplied with the boiler by the manufacturer, I thought that I was looking at simple things before resorting to the diverter valve. :shock:

Is the auto flow regulator not built in to the cold water supply cock or valve, I assume that is supplied by the manufacturer, what if that had not been fitted.

No no-one else is working on the appliance, is the MFR not set at the factory to the correct flow rate? If someone has opened up the MFR and increased the flow rate through the unit prior to me getting involved, would that not tend to reduce the temperature of the hot water

If someone had altered the D.H.W. Manual Flow Restrictor would that cause the problems with the hot water tap running cold :?:

Hi checked that, yes the red light is on when hot tap run. Also checked the flame, that increases in height when hot tap opened up, so what next :?:

Having removed all the power, checked the PCB for poor joints, found one, what do I do. Can I re-solder the suspect joint? Or do I buy a new PCB

But if I isolate from the power how will I know if a joint is dry or not. What am I looking for?

Thank you for that info, will try that

As indicated above. Turn on the kitchen sink hot tap, water runs warm for a couple of seconds then runs cold for a minute or so before getting warm again. The boiler is located adjacent to the kitchen sink. If the central heating is on, and the boiler is firing then on turning on the kitchen...
