Keston Boilers Guide

Hello,

My Keston combi C45 boiler turns off automatically after ten to fifteen minutes. I have restarted it but unluckily problem persists. The boiler is one year old & under warranty. Someone, please help me to sort it out immediately.

Thanks

David

Hi David, generally there are three common reasons behind this problem such as:

• Your Keston boiler is leaking
• The pressure relief valve of the boiler is broken or damaged. If this is a case, you have to replace it immediately with the help of an expert Keston engineer
• Lastly, another problematic thing is damaged thermostat as due to this, your Keston boiler will not be able to identify the water temperature. Conversely, the boiler will switch off automatically in order to keep the boiler away from overheating. I would advise you to check the flow of water.
