What does error E67 mean on a Keston Qudos boiler?

Error E67 on a Keston Qudos boiler indicates low water pressure below 0.4 bar. Use the filling loop to repressurise the system to approximately 1.2 bar. If pressure drops repeatedly, check for leaks and contact an engineer.

What does error E24 mean on a Keston C36 boiler?

Error E24 on a Keston C36 boiler indicates water pressure has been lost four times in 24 hours, suggesting a possible leak. Check around radiators and pipework for signs of water and contact a heating engineer to locate and repair any leaks.

What is a Keston magnetic system filter and do I need one?

A Keston magnetic system filter protects your boiler by capturing sludge, debris, and magnetic contaminants from the heating system. Installing a Keston 22mm System Filter with a Combi or System boiler extends the warranty from 5 to 7 years. The filter should be cleaned during annual servicing. It is fitted on the return pipe close to the boiler.

What pressure should my Keston boiler be at?

The ideal pressure for a Keston boiler is between 1.0 and 1.5 bar when the system is cold. This is displayed on the pressure gauge on the front of the boiler. Pressure naturally rises slightly when the heating is on. If pressure drops below 0.3 bar, the boiler will stop operating.

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.

How do I thaw a frozen condensate pipe on my Keston boiler?

Locate the condensate pipe, a white or grey plastic pipe running from the boiler through an external wall. Pour tepid water (not boiling) over the frozen section, or apply a hot water bottle around the pipe. Work from the top downwards. After thawing, press the restart button on the boiler.

Why does my Keston boiler keep losing pressure?

Frequent pressure loss usually indicates a leak somewhere in the heating system. This could be in the boiler, radiators, pipework connections, or the pressure relief valve. Check around radiators and beneath the boiler for signs of water. If you need to repressurise more than twice per year, contact a Gas Safe registered engineer.
