Vokera A01: ignition failure, flame not sensed
Check these first, then call an engineer
The boiler tried to light but didn't sense a flame. Vokera's manuals say to reset the boiler and check it then works.
What you can safely do
- Reset the boiler: wait two minutes, then turn the mode selector knob to the reset position, as Vokera's instructions describe.
- Check whether the boiler now runs normally.
Call a Gas Safe engineer if
- A01 comes back after a reset.
- You smell gas at any point. Leave the property and call 0800 111 999.
