A boiler that won't fire is not always a broken boiler. Often it's being told not to, or a protective lockout has tripped.
Five checks to make first
In this order:
- Power: is the fused spur on and the display lit?
- Gas: do other gas appliances work, and is the meter in credit?
- Pressure: is the gauge showing at least 1 bar?
- Controls: is the thermostat calling for heat and the timer within a scheduled period?
- Condensate: after a frost, check the external condensate pipe for ice.
Fault codes
Note any code on the display before resetting. It tells the engineer whether they're dealing with ignition, a flame sensor, a fan, a gas valve or an overheat lockout, and often means the right part arrives on the first visit.
Don't keep resetting
More than two or three resets on a repeating lockout risks further damage. If you'd rather not tackle it yourself, we cover Birmingham and surrounding areas, seven days a week.
