Vaillant · Turbomax Plus Boilers
The boiler failed to ignite. This could be due to a lack of gas supply, a fault with the ignition components, or, as a common issue, a frozen condensate pipe.
Click steps to track your progress.
Check if other gas appliances in your home (e.g., gas hob) are working to confirm your gas supply is active.
Ensure your boiler's condensate pipe, usually a plastic pipe outside, is not frozen. If it is, gently thaw it with warm water.
Restart the boiler by turning it off and on at the mains.
If the problem persists, contact a qualified heating engineer to inspect the gas valve and ignition components.
