To Gas112, thanks for your advice.. but the gas engineer has disconnected the condense pipe and said that it did not drip and so he was very sure that the leak is in the System. But I still suspect the leak is in the boiler somehow as it is 15 years old.. and I think I am going to get a new...

It seems that the pressure drops when I use the boiler to heat up water for my bath but if I don't have bath that day, then the drop in pressure is much less. Looks like when the boiler is heating water for my bath, the leak is worse and so it also proves that the radiator and pipe system is not...

after 5 days with the flow and return valves turned OFF to the radiators/system, the boiler pressure continues to show a drop in pressure over time like 0.3 bar over the 5 days. And when I turned the two valves back ON, there was no effect to the pressure reading. So my guess is that the leak...

Hi I have a 15 year old Potterton Combi Performa HE30 and the first 10 years are fine with no visible need to top up bar the annual service and then over the next 5 years, I have noticed I need to top up the pressure with increasing frequency starting with twice a year, then 4 times a year...

Hi My semi D house has normal roof tiles and was built in 1930. I noticed that some of the Sarking felt under the roof tiles and sitting on top of the beams are starting to deteriorate and some are broken. There is quite a bit of dust that are blown via the gaps of the tiles into my attic which...

Thanks.. I do intend to do it when the weather has improved but asked ahead of time now that I am sort of free during this break. I have a magnetic filter installed 5 years ago. it was just that my boiler was whistling at higher temperature that I thought my boiler may have scales and...

HI Will it damage my 13 year old Potterton Combi boiler if I put Fernox Cleaner F3 into the heating system and leave it running hot during winter for 5 days (or should it be less??) before draining it and put in the Fernox F1 Protector after words? Should I do it in the summer and so reduce...

I got a refurbished PCB and it works! Thanks gas112 for your advice!

By the way, the fan at the top was not running.

Thanks .. I will get a refurbed motherboard tomorrow and tried. Some asked me to change the cable-gas vale/igniter today and vowed that it will be a solution but it turned out not to work. Will check out the motherboard option. Thanks again!

Hi Thanks and checking eBay i can get a refurbished one with a year warranty fir £40 or a new one for £105. Is it an easy one for one replacement and does not need any post installation readjustment and diagnostics. I have basic knowledge in electronics and using multimeters, etc How certain...

Hi I have a 13 year old Potterton Performa 30 HE. Had been great for the last 12 years until I have got whistling sound in the last year which is reduced by turning the temperature of the water. Last few months, it turned off with lights (1) FLAME/Condensate fault and (3) Fan/FLUE counting from...
