heating broken :(
some electronic issue in the controller I suspect, as it heats water for the tap fine. just no heat to radiators... or maybe pump?
engineer due within 24 hours. so I have to stay home, ran out of milk too...
1. hold down top 3 buttons
2. wait until display changes + beep
3. hold down bottom 3 buttons
4. wait until display changes + beep
5. press middle bottom button
6. press top left button
7. press top left button again
then heating works. posting this boiler cheat code so I can favourite it for next time it happens
