Keston C55 no hot water

Hi Folks

My Keston C55 is only 2 years old stopped providing hot water. Today morning I had a cold shower for the third time, I have enough! Does anyone know what may be the problem. I add that there is no error message being displayed and it is proving the central heating.


Hi Alex,

Unfortunately if your boiler doesn’t display any error message it will be difficult to help. It can be thermostat, wrong setting of heat/hot water circuits. Did you try resetting? I would advice to call Keston service. Your boiler is still under warranty, you can always request a replacement appliance
