FAQs

What is a Printed Circuit Board (PCB) in a boiler?

The PCB is the main control unit of the boiler. It acts like the boiler's 'brain,' monitoring sensors, controlling heating cycles, managing safety features, and ensuring all components work together correctly.

Which Vaillant boiler models is this PCB (130391) compatible with?

This PCB is designed for Vaillant THERMOcompact and TURBOmax boiler models.

Can I install this PCB myself?

No, installing a boiler PCB is a job that requires specific expertise and qualifications. It must be performed by a Gas Safe registered engineer or a qualified heating engineer due to the risks involved with mains electricity and gas.

What are the signs of a failing PCB?

Signs can include the boiler not firing up, displaying error codes, intermittent operation, or shutting down unexpectedly. However, these symptoms can also be caused by other component failures.

How long does a boiler PCB typically last?

The lifespan of a PCB can vary depending on operating conditions, power surges, and overall boiler maintenance. With proper care and functioning ancillary components, they can last many years.

What is the GC Number for this part?

The GC Number for this Vaillant PCB is 283-765.

Troubleshooting

Boiler not firing up or showing error codes.

This could indicate a faulty PCB or other issues like sensor failure or ignition problems. A qualified engineer needs to diagnose the specific cause.

Intermittent heating or hot water supply.

Erratic behavior can sometimes point to a failing PCB. A professional assessment is required to confirm and rectify the problem.

Boiler shuts down unexpectedly.

This might be due to the PCB detecting a critical fault or failing itself. Consult a qualified engineer for diagnosis.

Setup, Compatibility & Care

Compatibility: This PCB is specifically designed for Vaillant THERMOcompact and TURBOmax boiler models. Always verify your boiler's model and check if part number 130391 is the correct replacement for your specific unit.

Setup: Installation of a boiler PCB is a complex task that involves working with mains electricity and gas components. It must be carried out by a qualified and registered heating engineer or Gas Safe registered engineer. Incorrect installation can lead to serious safety hazards, including fire, explosion, or carbon monoxide poisoning, and can also damage the boiler.

Care: PCBs are sensitive electronic components. During installation, engineers should take precautions against static discharge. Once installed within the boiler casing, the PCB is protected from dust and moisture. Regular boiler servicing by a qualified engineer helps to ensure that connected components are functioning correctly, reducing the strain on the PCB.
