Common Boiler Faults and Repairs We Carry Out
Boilers can develop a wide range of problems over time, from minor annoyances to complete breakdowns. At Boilers4Essex, our engineers diagnose issues quickly and carry out reliable repairs using genuine parts wherever possible. Here are some of the most common faults we deal with across Essex:
🔧 Low Boiler Pressure
The fault: Your boiler keeps losing pressure, or the pressure gauge reads below 1 bar.
Our repair: We check for leaks, repressurise the system, and replace faulty pressure relief valves or expansion vessels if required.
🔧 No Heating or Hot Water
The fault: Radiators stay cold or hot water won’t run.
Our repair: We test diverter valves, thermostats, and pumps, replacing defective parts to restore full heating and hot water.
🔧 Leaking or Dripping Boiler
The fault: Water leaking from pipework, joints, or the boiler casing.
Our repair: We identify the source of the leak, repair or replace damaged seals, pipework, or heat exchangers.
🔧 Strange Noises (Banging, Whistling, Gurgling)
The fault: Noises inside the boiler or heating system caused by limescale build-up, trapped air, or faulty components.
Our repair: We flush the system, bleed radiators, and replace faulty pumps, fans, or heat exchangers.
🔧 Boiler Lockout or Error Codes
The fault: Boiler shuts down or displays fault codes.
Our repair: Using diagnostic tools, we trace the error to ignition systems, gas supply, or sensors, then replace or reset components.
🔧 Frozen Condensate Pipe
The fault: In winter, outdoor condensate pipes freeze, shutting down the boiler.
Our repair: We safely thaw frozen pipes, insulate them, and advise on long-term prevention.
🔧 Pilot Light or Ignition Failure
The fault: Boiler won’t ignite or keeps cutting out.
