Worcester LPG 24i Junior 2013 Boiler F.A.Q.

How do I reset my Worcester LPG 24i Junior 2013 Boiler?

To reset the boiler, press and hold the reset button until the reset light turns off. This should take about 3 seconds.

What should I do if my boiler is leaking water?

First, turn off the water supply and power to the boiler. Then, contact a qualified heating engineer to inspect and repair the leak.

Why is my Worcester 24i Junior boiler not heating water?

Check if the boiler is receiving power and that the thermostat is set correctly. If the problem persists, it may be due to a faulty diverter valve or a blocked heat exchanger.

How often should I service my Worcester LPG 24i Junior boiler?

It is recommended to service your boiler annually to ensure it operates safely and efficiently.

What type of gas does the Worcester 24i Junior 2013 use?

The Worcester 24i Junior 2013 boiler is designed to use LPG (liquefied petroleum gas).

What is the ideal pressure for my Worcester 24i Junior boiler?

The ideal pressure is between 1 and 1.5 bar when the system is cold.

How can I increase the pressure in my boiler?

Locate the filling loop below the boiler and open the valves slowly until the pressure reaches the recommended level. Then, close the valves.

What should I do if my boiler is making unusual noises?

Unusual noises may indicate trapped air or a build-up of limescale. Bleed the radiators or consult a heating engineer for a system flush.

How can I bleed my radiators to improve heating efficiency?

Turn off the heating and use a radiator key to open the bleed valve. Allow trapped air to escape until water starts to flow, then close the valve.

What should I do if the boiler won't ignite?

Check the gas supply and ensure there are no obstructions in the flue. If the issue remains, consult a professional engineer to investigate further.
