Worcester Greenstar 9Ri Boiler F.A.Q.

How do I reset the Worcester Greenstar 9Ri Boiler?

To reset the boiler, locate the reset button on the front panel of the boiler. Press and hold the button for 3 to 5 seconds until the reset light stops flashing. Release the button, and the boiler should restart.

What should I do if the boiler is not igniting?

Check if the gas supply is turned on and that there are no obstructions in the flue. Ensure that the system pressure is within the recommended range (usually 1 to 1.5 bar). If the problem persists, consult a qualified technician.

How often should I service my Worcester Greenstar 9Ri Boiler?

It is recommended to service the boiler annually. This helps ensure efficient operation and extends the life of the boiler.

Why is my boiler making a whistling noise?

A whistling noise could be due to trapped air in the system or a problem with the water flow. Bleeding the radiators or adjusting the pump speed may resolve the issue. If the noise persists, contact a heating engineer.

What does the error code EA mean on my Worcester Greenstar 9Ri Boiler?

Error code EA indicates a failure to ignite. Check the gas supply and ensure there is adequate pressure. Reset the boiler and try again. If the error continues, seek professional assistance.

How can I increase the water pressure in my boiler?

Locate the filling loop underneath the boiler. Open the valves slowly until the pressure gauge reads between 1 and 1.5 bar. Close the valves tightly after achieving the correct pressure.

Is it normal for the boiler to lose pressure regularly?

No, regular loss of pressure may indicate a leak in the system or faulty components. Inspect radiators, pipes, and the boiler itself for any visible leaks and repair as needed.

Can I install the Worcester Greenstar 9Ri Boiler in a bathroom?

Yes, the boiler can be installed in a bathroom, but it must be placed in accordance with current regulations regarding electrical zones and ventilation. Always consult a qualified installer for bathroom installations.

What should I do if the radiators are not heating up properly?

Check if the radiators need bleeding to release trapped air. Ensure the thermostat is set correctly and that the boiler is turned on. If the issue persists, inspect the diverter valve or consult a professional.

How do I bleed a radiator in the central heating system?

Turn off the heating system and wait for the radiators to cool. Use a radiator key to slightly open the bleed valve at the top of the radiator. Allow air to escape until water starts dripping, then close the valve tightly.
