Vokèra Boilers and Lights errors
Vokèra boilers are prone to errors related to lighting issues. When this occurs, the LCD on your boiler will not display any information, including error codes. Instead, error codes will be indicated by lights. To effectively address these issues, it is crucial to comprehend the various types of lighting problems and their causes in vokèra boilers.
Flashing Red Light Problem
A flashing red light on your Vokèra boiler is a warning sign that your heating and hot water supply will be disrupted. If your boiler is relatively new, it should be covered under warranty. However, this issue can be caused by various factors and requires immediate attention from a Gas Safe-registered engineer.
To help you identify the problem, here are some possible reasons for the flashing red light:
- Low water pressure: Check the pressure gauge on your boiler and ensure it is within the recommended range. You may need to top up the water pressure if it is too low.
- Faulty thermostat: If the thermostat is not working correctly, it can cause the boiler to shut down. Check the settings and replace the thermostat if necessary.
- Blocked condensate pipe: A blocked condensate pipe can cause the boiler to shut down. Check for any blockages and clear them if possible.
- Air in the system: If there is air in the system, it can cause the boiler to shut down. Bleed the radiators to release any trapped air.
- Broken or stuck diverter valve: The diverter valve on your boiler might be stuck, due to which you might be getting no heating or hot water from your Vokèra boiler. To deal with it, you should contact a Gas Safe engineer right away.
Flashing Green Light Problem
When the green light on your boiler is constantly on, it indicates that the flame is operating correctly. However, if the light is flashing, it could indicate an issue with your hot water sensor or that your boiler is on standby. If the red light is also flashing alongside the green light, it is a serious matter that requires immediate attention. In this case, contacting a GasSafe engineer is crucial.
It is important to keep an eye on your boiler’s lights to ensure they are functioning properly. A flashing green light may seem like a minor issue, but it could be a sign of a larger problem. You can avoid more significant and costly repairs by addressing the issue promptly.
The red light is on, but the green light is off.
When the red light is on but the green light is off, which indicates your boiler is not operational and it enters lockout mode. This could be due to the following reasons:
- One of the main reasons is the central heating pump’s failure; it is not circulating water properly throughout your central heating system to your radiators.
- Overheating issues cause your boiler to get too hot.
- Faulty fan that is preventing the harmful gases from getting expelled out of the flue.
Red and green lights on
When the red and green lights are blinking in a Vokèra boiler, it indicates a problem with the ignition system. The green light usually indicates that the boiler is receiving power and functioning properly, while the red light typically signals an issue such as low pressure or a faulty pump.
When both red and green lights are on at once, there may be an issue with the wiring or electronic components of the boiler. This problem requires investigation by a certified professional, as electricity poses a potential danger if you don’t know enough about it.
Only a professional technician can safely and efficiently diagnose and repair this issue to prevent damage to the system and ensure its proper functioning.
How to reset a Vokèra boiler
Resetting a Vokèra boiler is a simple process that can be easily performed by following some basic steps. Firstly, finding the Vokèra boiler reset button location is important; it will be typically found near the control panel. Then, after locating the panel, turn off your boiler and press the reset button for at least five seconds before releasing it. This should clear any error codes or faults that may have caused your boiler to shut down unexpectedly. To prevent future issues, it is recommended that you check your boiler’s manual for troubleshooting tips and schedule regular maintenance with a professional technician.
Only attempt to reset your Vokèra boiler if you’re confident, as electrocution and other hazards may occur if you do it incorrectly. Always take the necessary precautions when working with electrical devices and seek professional help if needed to ensure the safe operation of your home heating system.
