Common Vaillant Boiler Fault Codes
 

Vaillant boilers are designed to display fault codes when something goes wrong. Here are some of the most common ones:
 

F22 – Low Water Pressure
 

• Often caused by a drop in system pressure

• May require repressurising the system

• Could indicate a leak if persistent
   

F28 – Ignition Failure
 

• Boiler fails to ignite

• Possible causes: gas supply issues, faulty ignition lead, or valve problems
   

F29 – Flame Failure
 

• Flame goes out during operation

• Often linked to gas supply interruptions or flue issues
   

F75 – Pump or Pressure Sensor Issue
 

• Boiler struggles to detect pressure increase

• Common causes: faulty pump, blocked system, or sensor failure
   

F61 – Gas Valve Fault
 

• Problem with gas valve control

• Requires professional repair
   

⚠️ Important: While some issues like low pressure can be resolved by homeowners, most fault codes should be diagnosed by a Gas Safe registered engineer.
