Worcester LPG 27i System Compact 2014 Boiler F.A.Q.

How do I reset the Worcester LPG 27i System Compact 2014 Boiler?

To reset the boiler, press and hold the reset button located on the front panel until the reset light stops flashing. This should take about 5 seconds.

What should I do if the boiler is not heating water?

Check if the thermostat is set correctly and ensure the boiler is receiving power. If the issue persists, inspect the pressure gauge to ensure the pressure is between 1 and 1.5 bar.

How often should I service my Worcester LPG 27i System Compact 2014 Boiler?

It is recommended to service your boiler annually to ensure optimal performance and efficiency.

Why is my boiler making a loud banging noise?

Loud banging noises can be caused by trapped air in the system or a buildup of limescale. Bleed the radiators and consider using a descaling agent.

How can I increase the water pressure in my Worcester LPG 27i Boiler?

Locate the filling loop beneath the boiler, then open the valves to allow water to flow into the system until the pressure reaches 1-1.5 bar. Close the valves afterward.

What does the error code EA mean on my Worcester 27i Boiler?

Error code EA indicates an ignition failure. Check the gas supply and ensure there are no obstructions in the flue.

Can I use the Worcester 27i Boiler with smart thermostats?

Yes, the Worcester 27i Boiler is compatible with most smart thermostats, but it is recommended to check compatibility with the thermostat manufacturer.

How do I bleed a radiator connected to my Worcester 27i Boiler?

Turn off the heating and use a radiator key to open the bleed valve. Allow air to escape until water begins to leak out, then close the valve tightly.

Why is the boiler losing pressure regularly?

Regular pressure loss can be due to leaks in the system, faulty expansion vessel, or a malfunctioning pressure relief valve. Inspect the system for visible leaks and consult a technician if necessary.

What should I do if I smell gas near the boiler?

If you smell gas, immediately turn off the gas supply, ventilate the area, and contact a Gas Safe registered engineer. Do not attempt to fix the issue yourself.
