Vaillant PCB VCM 182/1 E - Code 734664.14
The Vaillant VCM 182/1 E - 734664.14 PCB is the component that controls the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, may lock out, or may exhibit erratic behavior, potentially displaying faults such as F.61, F.62, F.63, F.64, or F.65. This board is compatible with models from the Turboblock VCM range (such as VCM 182/1 E and VCM 242/1 E) and VC range (such as VC 240/1). It should be replaced when the mentioned symptoms occur or the indicated fault codes are recorded.

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, with no display or lights on.
Cause: The PCB distributes power to all the electronics of the boiler.
Before discarding it, check the internal fuse on the PCB and verify that stable power is reaching the main connector.
- 02
An error code appears on the screen that does not clear when disconnecting the boiler.
Cause: The PCB stores the safety fault in its memory, and if the fault is internal, it does not clear itself automatically.
Note the exact code and consult the manual before purchasing: it may indicate a problem with an external sensor and not with the PCB.
- 03
The heating works well, but the domestic hot water comes out cold or lukewarm.
Cause: The PCB manages the switching between heating and domestic hot water, and if the relay or the output fails, one of the two services is lost.
Check that the water flow activates the domestic hot water sensor; a small click is usually noticeable before considering that the PCB is faulty.
- 04
The burner ignites, but the flame fluctuates erratically without changes in the heat demand.
Cause: The modulation electronics are on the PCB, and a fault here causes an unstable flame even though the gas is arriving correctly.
First, check the gas inlet pressure and the condition of the ionization electrode, as they can produce a similar symptom.
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.
