Fault codes
All Vokèra codes that apply to this model.
- A01The burner failed to light and the appliance has locked out. Check the gas supply and, in cold weather, the condensate pipe before calling anyone.Get it checked
- A04System water pressure is below the minimum the appliance will run at. Topping the system back up to 1.2 bar normally clears it straight away.Usually simple to fix
- A02The safety limit thermostat has tripped on overheat. In practice this nearly always means water has stopped circulating properly.Get it checked
- A03The appliance cannot confirm the fan is running correctly, so it will not permit the burner to light. This needs an engineer.Get it checked
- A11The appliance is detecting a flame when there should not be one. Turn it off at the fused spur and get a Gas Safe engineer out.Stop — call an engineer
- A09The flue gas sensor has recorded a temperature above the safe limit, or the sensor itself has failed. Either way the appliance stops.Get it checked
- A07The primary flow sensor is reading out of range or has failed. The appliance stops because it can no longer tell how hot it is running.Get it checked
