    Vokera Boiler Red Light on Error: Cause and Fix

    A flashing or constant red light means that your boiler has a fault and will possibly lockout. As a result, your home will be without hot water or heating.

    Several issues can be casing this. It is, of course, recommended that you should consult a Gas Safe engineer to fix this find the right cause and fix your problem. However, on this page we can help you know what might be causing this issue.

    Causes of Vokera Red Light:

    Vokera boilers with constant green light and no red light can indicate that there is nothing to worry about and your boiler will supply heating and hot water as it should. However, if you see a red light on its own or alongside the green light then there might be a possible fault with your boiler.

    Red Light On and Green Light Off Meaning

    A constant red light on your Vokèra boiler indicate that the unit has gone into lockout for safety reasons and to prevent further damage. Some of the potential faults behind this can include:

    • The pump is not circulating hot water around the central heating system or to the taps when needed.
    • Harmful flue gases are not being expelled because of an issue with the fan.
    • The boiler is overheating

    Red and Green Lights On Meaning

    If you can see both green and red lights on your Vokera boiler at the same time, whether they’re constant or flashing, your boiler might have one of the following issues:

    There is a fault in Heating temperature sensors

    Incorrect water pressure (either too low or too high)

    Flashing Green Light Meaning

    A constant green light on your Vokera boiler is a sign that the flame within the boiler is working, and that’s what you want to see. if the green light start flashing, that’s when you know there might be something wrong with your boiler.
