The Vaillant 0020149950 Printed Circuit Board (PCB) is a genuine replacement control module that serves as the central electronic brain of your EcoCraft boiler. This PCB manages key operational functions including ignition sequencing, pump and fan control, sensor input processing and safety monitoring. By coordinating these systems, it ensures smooth, efficient heating and hot-water performance, accurate diagnostics and controlled responses to changing demand. A faulty PCB can lead to erratic operation, fault codes or loss of control, making correct replacement essential for dependable boiler performance.

This printed circuit board is compatible with Vaillant EcoCraft series boilers that reference part number 0020149950 in their technical documentation. To ensure correct fitment and reliable operation, always verify that the part number matches your existing board or consult your boiler’s service information before installation, as control modules are model-specific and cannot be interchanged freely between different series.

Supplied ready for direct replacement, the 0020149950 Printed Circuit Board integrates with the boiler’s original wiring harness and sensor interfaces without modification when installed by a qualified engineer. Choosing this genuine Vaillant component helps restore proper system control, supports accurate fault detection and contributes to efficient, reliable heating and hot-water performance in compatible EcoCraft boilers.
