Vokèra Vision fault codes
Built 2014 onwards
Combi and system boilers using the A01 to A11 set described here, read from an LCD and reset by turning the mode selector knob. Superseded by the Vision Plus, which renumbers the same faults as E010 to E099 and has a RESET key instead.
Codes on the Vision follow the same Vokèra scheme as the rest of the range. Where a code behaves differently on this generation, the code page says so.

- 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
