Where do I find the serial number on my Keston boiler?

The serial number on a Keston boiler is typically found on the rating plate, which is usually located inside the front panel or underneath the boiler. The serial number is needed for warranty registration and when ordering spare parts. If you have the original service book, the serial number should also be recorded there.

What warranty do Keston boilers have?

Keston Combi 2 and System 2 boilers come with a 5-year warranty as standard, which can be extended to 7 years when installed with a Keston System Filter and both are registered together. Keston Heat 2 boilers have a 2-year standard warranty, upgradeable to 5 years with free commissioning by Keston. Annual servicing by a Gas Safe registered engineer is required to maintain the warranty.

How do I reset my Keston boiler after a fault?

For most Keston models, press the Restart button on the boiler fascia. For models with a mode control knob, turn it to the Reset position, then immediately return it to the On position. Switching the boiler off and on at the mains will not clear a fault lockout.

What error codes indicate a frozen condensate pipe on a Keston boiler?

On Keston Combi and System boilers, error codes L2 or F2 indicate possible frozen condensate. On Keston Heat boilers, the display shows "Check Condense". On Heat 2 boilers, ignition lockout or flame loss fault codes may appear. The boiler may also make a gurgling noise. If in doubt, contact a Gas Safe registered engineer.
