Why does my boiler keep locking out in Glasgow?

A lockout is the boiler protecting itself after detecting a condition it cannot safely or reliably operate through. The cause might be ignition failure, loss of pressure, overheating, condensate problems, a sensor fault or another manufacturer-specific issue.

Read the displayed fault code and check the user manual before resetting the boiler. One reset may be an appropriate user action on some appliances, but repeated resets are not a repair. If the same fault returns, the underlying cause needs to be diagnosed.

When contacting a Glasgow boiler engineer, provide the make, model, exact fault code, system pressure and what the boiler was doing when it stopped. Doherty's boiler repair service deals with heating loss, hot-water faults, error codes and pressure problems and can use those details to narrow down the likely issue before the visit.
