Engineers assess components such as sensors, control boards, and internal valves to determine how the system is responding to demand. This helps identify whether faults relate to control signals, flow conditions, or component wear. ✔ No-pressure guidance throughout repairs ✔ Loss of heating or inconsistent hot water output
