What causes the Vokera Red LED Flashing fault?

This fault occurs when the boiler fails to light or loses its flame three times in a row, causing it to stop for safety reasons. The most common reasons include a lack of gas supply, a build-up of carbon on the ignition probe, or a component failure that prevents the burner from firing up correctly.

This issue is more frequent during the first cold snap of autumn when a boiler is turned back on after months of inactivity, often due to a stuck gas valve or debris in the system.

Typical repair cost £120-250 (including labour)

DIY fix possible

Locate the main control dial on the front of the boiler.Turn the dial to the 'OFF/RESET' position and wait for 5-10 seconds.Turn the dial back to the 'Hot Water' or 'Heating & Hot Water' position to restart the boiler.
