Common Boiler Faults We Fix in Sheffield
Boiler Not Firing Up
One of the most common boiler faults. If your boiler is not firing up it could be caused by a faulty ignition, a problem with the gas supply, low pressure or a fault with the printed circuit board. Our engineers will diagnose the fault and provide a fixed price quote for the repair.
Boiler Losing Pressure
If your boiler pressure gauge reads below 1 bar your boiler may cut out or fail to heat properly. Pressure loss is usually caused by a water leak somewhere in the system or a faulty pressure relief valve. An engineer can identify the cause and carry out the necessary repair.
No Hot Water
If you have heating but no hot water the most likely cause is a faulty diverter valve. This is a common fault on combi boilers and is usually straightforward for an experienced engineer to diagnose and replace.
Boiler Making Strange Noises
Banging, gurgling or whistling noises from your boiler can indicate several issues including kettling caused by limescale build up, a failing pump or air in the system. Our engineers can identify the cause and advise on the best course of action.
Pilot Light Keeps Going Out
If your pilot light repeatedly goes out it could indicate a faulty thermocouple, a problem with the gas supply or a draught affecting the flame. This should always be investigated by a Gas Safe engineer.
Boiler Cutting Out Repeatedly
A boiler that keeps cutting out is usually protecting itself from a fault. Common causes include low water pressure, overheating, a faulty pump or a blocked condensate pipe. An engineer will run a full diagnostic to identify the root cause.
Radiators Not Heating Up
If some or all of your radiators are not heating properly the cause could be air in the system, a failing pump, a stuck motorised valve or a buildup of sludge in the pipework. Power flushing or bleeding the radiators may resolve the issue.
Boiler Leaking Water
A leaking boiler should always be investigated by a Gas Safe engineer as soon as possible. Common causes include a faulty pressure relief valve, a worn pump seal or a cracked heat exchanger. Do not ignore a boiler leak.
