Keston Appliance Repair in Heatons North

What does error L2 mean on a Keston S30 boiler?

Error L2 on a Keston S30 boiler indicates flame loss lockout, commonly caused by a frozen condensate pipe in winter. 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, locate the condensate pipe and pour warm water along it to thaw. Reset the boiler once thawed. If the fault persists, contact a Gas Safe registered engineer.

What does error F1 mean on a Keston S30 boiler?

Error F1 on a Keston S30 boiler indicates low water pressure. Repressurise the system using the filling loop until the gauge shows approximately 1.2 bar. If pressure continues to drop, check for visible leaks and contact an engineer.

What does error E44 mean on a Keston C40 or C55 boiler?

Error E44 on a Keston C40 or C55 boiler indicates low water pressure. Use the filling loop to add water until pressure reaches approximately 1.2 bar. If pressure drops repeatedly, check for leaks and contact an engineer.

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 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 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 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.

Are Keston boilers compatible with smart thermostats?

Keston boilers are compatible with OpenTherm technology, which allows communication between the boiler and smart thermostats. OpenTherm-compatible thermostats enable the boiler to modulate its output for improved efficiency and comfort. Popular smart thermostats with OpenTherm support can achieve energy savings of up to 14 percent compared to standard on-off controls.

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 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.
