To reset your Worcester Greenstar 27i System Boiler, press the reset button on the control panel for three seconds. The reset button is usually marked with a symbol of a flame with a line through it.
First, check if the thermostat is set correctly and ensure the boiler is receiving power. If the issue persists, examine the pressure gauge to ensure it's between 1 and 1.5 bar. If these steps don't resolve the issue, consult a professional engineer.
Gurgling sounds can be due to air trapped in the system or low water pressure. Bleeding your radiators and checking the pressure gauge can help resolve these issues.
It is recommended to service your boiler annually to ensure it operates efficiently and safely. Regular maintenance can prevent breakdowns and prolong the boiler's lifespan.
The error code EA indicates that the boiler has failed to ignite. Check if the gas supply is turned on and there is no obstruction in the flue. If the issue persists, contact a qualified engineer.
To increase the water pressure, locate the filling loop and turn the valve until the pressure gauge reaches 1 to 1.5 bar. Ensure to close the valve after reaching the desired pressure.
The correct operating pressure for the boiler should be between 1 and 1.5 bar when the system is cold. If the pressure is outside this range, it may require adjustment or maintenance.
Pressure loss can occur due to leaks in the system, a faulty pressure relief valve, or air trapped in the radiators. Inspect for visible leaks and bleed radiators to resolve this issue.
To bleed your radiators, turn off the heating system and use a radiator key to open the bleed valve. Allow air to escape until water starts to drip, then close the valve. Repeat for each radiator.
If your boiler is leaking water, turn off the water supply and power to the boiler. Contact a qualified heating engineer to inspect and repair the leak as soon as possible.
