Effective Vaillant repairs begin with understanding how the boiler regulates heating and hot water under real operating conditions. 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.
