Vokera Boiler Red Light On

Vokera boilers without a digital display won’t have an error code to let you know what’s wrong with the boiler, however, they do have red and green lights that will either remain on constantly or begin flashing depending on the situation. Read our guide to the Vokera boiler red light on Boiler Guide to get your boiler back up and running.
