FAQs
Can I install the Vaillant 130837 Main PCB myself?
No. Due to gas safety regulations, this part must be fitted by a certified Gas Safe engineer.
Is this a genuine Vaillant part?
Yes, this is an original manufacturer replacement part designed for Vaillant appliances.
Which models is this PCB compatible with?
This part is designed specifically for the Ecomax Pro and eco MAX VU condensing boiler ranges.
Does the PCB come pre-programmed?
The PCB is designed to be plug-and-play for the compatible units, though system-specific adjustments may be required by the engineer during commissioning.
What should I do if I think my PCB is faulty?
Contact a Gas Safe registered engineer to diagnose the boiler; they can confirm if the PCB is the source of the failure before you purchase a replacement.
Troubleshooting
Boiler failing to respond to thermostat commands
Check that the PCB connections to the external thermostat terminals are secure and that the PCB is receiving the correct voltage signal.
System displaying persistent fault codes
Consult the specific boiler service manual to see if the error code relates to the PCB communication or a peripheral sensor; if wiring is sound, the PCB may require replacement.
No display or power on the boiler front interface
Verify the boiler fuse and power source; if power is confirmed at the terminals but the display remains dead, the PCB is likely the culprit.

Setup, Compatibility & Care
This part is designed specifically for the Vaillant Ecomax Pro and eco MAX VU series. Because this board manages high-voltage components and gas-related safety mechanisms, it must never be installed by an unqualified individual. Always ensure the power supply is fully isolated before any inspection or removal of the old board. When handling the PCB, avoid touching the gold-plated connectors or sensitive integrated circuits to prevent electrostatic discharge damage. Store in a dry, static-free environment if the part is not being installed immediately upon receipt.
