How to handle common boiler fault codes
Play it safe: call an expert.
Should you notice any unusual noises, smells, or error messages from your appliance, we strongly advise against attempting to repair it yourself. Instead, contact a qualified installer as soon as possible, ideally the expert who installed the heating system. This will ensure they are fully familiar with the technology.
Boiler fault code prevention with service
Let our experts see faults before you even notice them with a regular service
Regular servicing of your heating system increases efficiency and reduces energy consumption – resulting in long-term cost savings. Annual maintenance is recommended. This helps to identify and address wear and tear early, preventing breakdowns during the winter and increasing reliability. Qualified technicians inspect burners, heat exchangers, filters, pumps, and safety features, enabling the early detection of potential hazards such as carbon monoxide. Furthermore, regular maintenance extends the system's lifespan and is often a prerequisite for warranty claims. Ideally, the heating system should be serviced before the heating season to ensure safe, reliable, and efficient operation.
