What causes the Vokera Reset light on fault?
This fault occurs when the boiler tries to ignite but fails to establish or maintain a stable flame, prompting the system to shut off the gas for safety. The most common reasons include a worn-out ignition spark, a blockage in the gas supply, or an issue with the internal sensors that detect the flame.
This issue can be more frequent during extreme cold snaps if the gas pressure in the local network fluctuates or if moisture has affected the external gas meter.
