Boiler
Boiler displays an error code
The code displayed by the boiler is the most important information for initial review. Without it, diagnosis is much harder.
Possible causes
- low system pressure
- no gas or ignition problem
- blocked flue/exhaust
- blocked pump or faulty sensor
- electronic board or connection issue
What to send
- photo of display and error code
- boiler brand and model
- pressure shown on gauge
- what happened before the error
- whether the error returns after reset
Caution
Do not remove covers or adjust gas. Ignition, exhaust or gas errors require authorized inspection.
