PCB for Vaillant Boilers VC, VCM, VU, and VUW (series /1)
Control PCB for Vaillant boilers of the /1 series (VC, VCM, VU, and VUW). It includes the transformer that reduces the mains voltage to 21V for the secondary circuit, protected by a 1.25A fuse. It is responsible for the overall operation of the unit. It is replaced when the boiler does not ignite, does not respond, or shows electronic faults.

How to check if ref. 130438 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 130438. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the PCB 130438 resolves.
The PCB controls the ignition, modulation, and safety features of the boiler. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite or respond to any controls, as if it has no power.
Cause: If the transformer on the PCB does not deliver 21V to the secondary circuit, all the electronics will be without power and nothing will start.
Measure with a multimeter if the 1.25A fuse has blown before declaring the PCB dead.
- 02
The display is completely off, with no indicators or lights on.
Cause: It is the typical signal that the secondary fuse has blown and has cut off the power to the control part.
Check if the fuse is visibly burnt or measure its continuity before replacing the PCB.
- 03
An error code related to the PCB (control board) is displayed on the screen.
Cause: The control board itself detects an internal management fault and displays it instead of starting the burner.
Note the exact code and try a reset of the boiler; some faults of this type recover on their own.
Fault codes from Vaillant that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.61 | Gas valve activation error. | The relay/output stage of the PCB (auxiliary/main) does not correctly switch the gas valve. Check the power supply to the valve at the terminals, continuity of the harness, and if everything is correct, replace the PCB to confirm. |
| F.62 | Delay in gas valve disconnection. | The PCB keeps the gas valve energized longer than it should (control/relay fault). Check that the valve closes properly and that the wiring is correct; if the issue persists, measure the control voltage and confirm by replacing the PCB. |
| F.63 | Fault: EEPROM (electronics). | Corruption/defect of the EEPROM memory on the PCB. Check resets and parameters; the standard check is to replace the board with a new or programmed one to rule out the fault. |
| F.64 | Fault in the electronics/NTC. | Fault in the measurement/ADC stage or sensor power supply on the PCB. Check NTC and wiring; if the sensors measure correctly but the fault code persists, the cause is the PCB. |
| F.65 | Fault: electronics temperature too high. | The thermal sensor on the PCB detects overheating or the PCB itself is damaged. Check ventilation/location and temperatures; if they are normal and the error repeats, replace the PCB. |
| F.67 | Fault: electronics/flame (flame signal not plausible). | The detection/ionization stage on the PCB delivers an incoherent signal. Check the electrode, cable, and polarity; if everything is correct, the fault is in the PCB. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
