What does error F2 mean on a Keston S30 boiler?

Error F2 on a Keston S30 boiler indicates flame loss during operation. If you smell gas, do not operate any switches or appliances, ventilate the area if safe to do so, evacuate the property, and call the gas emergency services from outside. Otherwise, check if the condensate pipe is frozen and thaw if necessary. Try resetting the boiler. If the fault recurs, contact a Gas Safe registered engineer.

What does error E03 mean on a Keston C40 or C55 boiler?

Error E03 on a Keston C40 or C55 boiler indicates the gas valve is faulty or not properly connected. If you smell gas, do not operate any switches or appliances, ventilate the area if safe to do so, evacuate the property, and call the gas emergency services from outside. Do not attempt any repairs. Contact a Gas Safe registered engineer immediately as gas valve faults must only be handled by qualified professionals.

What does error F3 mean on a Keston S30 boiler?

Error F3 on a Keston S30 boiler indicates a fan fault. Contact a Gas Safe registered engineer to check the fan, wiring, and speed sensor.

What does error E02 mean on a Keston C36 boiler?

Error E02 on a Keston C36 boiler indicates false flame detection - the boiler is detecting a flame signal before ignition has started. This requires a Gas Safe registered engineer to check the power supply polarity and flame sensing electrode.

What does error E03 mean on a Keston C36 boiler?

Error E03 on a Keston C36 boiler indicates boiler overheat. Allow the boiler to cool down, check that radiator valves are open and the pump is running. Contact a qualified engineer to investigate potential blockages and pump operation.

What should I do if my Keston boiler does not work after a power cut?

After a power cut, first check that the electrical supply has been restored. Check the system pressure is between 1.0 and 1.5 bar. Press the Restart button on the boiler fascia. You may also need to reset the programmer clock to the correct time. If an error code is displayed or the boiler fails to restart, contact a Gas Safe registered engineer.

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.

How do I repressurise my Keston boiler?

Turn off the boiler and allow it to cool for at least an hour. Locate the external filling loop beneath the boiler. Attach the filling loop, open both valves slowly, and watch the pressure gauge until it reaches 1.0 to 1.5 bar. Close both valves, then remove and store the filling loop.

Why is my Keston boiler making unusual noises?

Gurgling usually indicates trapped air and can be resolved by bleeding radiators. Banging may indicate pressure irregularities or sediment buildup. A high-pitched whistling (kettling) suggests limescale in the heat exchanger. For persistent noises other than gurgling, contact a Gas Safe registered engineer.

How do I register my Keston boiler warranty?

Your Keston boiler warranty must be registered within 30 days of installation to qualify for the full warranty period. If not registered within 30 days, the warranty is limited to 12 months. Your installer may have already registered the warranty on your behalf. To check or register, you will need the boiler serial number and installation date.
