Boiler Repair & Servicing in Exmouth
Common Boiler Problems
These are the most common boiler faults reported by homeowners in Exmouth and East Devon.
No heating or hot water
The most common boiler complaint. Could be caused by a faulty diaphragm, airlock, motorised valve or low water levels.
Boiler keeps cutting out
Your boiler may shut down due to low water pressure, a blocked condensate pipe or a faulty thermostat.
Strange noises
Banging, gurgling or whistling sounds often indicate air in the system, low water pressure or kettling caused by limescale build-up.
Leaking or dripping
Leaks can come from internal components such as the pressure valve or pump seal. Never ignore a boiler leak — call an engineer promptly.
Low boiler pressure
If the pressure gauge reads below 1 bar, your boiler may struggle to heat your home. This can be caused by a leak or a recently bled radiator.
Pilot light keeps going out
A faulty thermocouple, draught or gas supply issue can cause the pilot light to extinguish repeatedly.
Radiators not heating up
Cold spots or radiators that will not heat often point to sludge build-up in the system. A power flush may be needed.
Error codes on display
Modern boilers display fault codes when something goes wrong. A Gas Safe engineer can diagnose the code and carry out the correct repair.
