Keston C55 leaks

Hi All

I have Keston boiler model 55 and was pretty happy with it for years now, unfortunately I realized last week that boiler starts to leak. What is wrong? Any idea how to fix it

Best Regards



Hi Robert

This is commonly know problem with C55 / C40 Keston boilers. To fix it you will need to replace heat exchanger gaskets and most probably fan. Repair doesn’t take much time, but should be done very fast after realizing the fault otherwise your boiler will break completely!
