Simple checks to help you understand the fault and explain it clearly. Do not attempt gas, oil or electrical work yourself.
Check whether the boiler display is on, whether your thermostat is calling for heat and whether other gas appliances are working. If there is any smell of gas, turn the gas off, ventilate the property and call the emergency gas number before arranging a repair.
Many boilers stop working when pressure drops too low. Look for the pressure gauge and note the reading, but only top up the system if you know the correct filling-loop process for your model.
Air trapped in radiators can stop heat circulating properly. Bleeding radiators may help, but repeated air in the system can point to a leak, corrosion or pressure issue that needs checking.
Unusual noises can come from trapped air, poor circulation, scale build-up or pump issues. Switching the system off and booking a check is usually safer than waiting for the sound to get worse.
Take a photo of the code before resetting anything. A reset may get the boiler running briefly, but the code gives useful clues for proper fault finding.
If the boiler keeps needing a reset, treat it as a fault rather than a nuisance. Repeated lockouts often mean the system is protecting itself from an underlying problem.
