Explanations/causes
No heat removal, STB/interruption, possibly short in gas
2)
valve , internal fuse defective; let device cool down and
reset; if this fault occurs several times, inform heating
3)
specialist
No heat removal; pump defect,radiator valves closed
Check or refill water pressure
monitor
Reset, if the fault re-occurs several times, contact heating
specialist, lack of gas, polarity of mains connection, safe-
ty period, check ignition electrode and ionisation current
