Vaillant PCB VCM 242/1 E - Ref. 130438
The Vaillant VCM 242/1 E PCB - Ref. 130438 is the ideal spare part for Vaillant boilers from the Turboblock VCM and VC range. Its main function is to control the ignition, burner modulation, pump, and safety features of the boiler. When this component fails, the user may notice that the boiler does not start, locks out, or exhibits erratic behavior. This component is compatible with models such as VCM 182/1 E, VCM 242/1 E, and VC 240/1, among others. A technician must confirm through diagnosis whether the PCB needs to be replaced when errors such as F.61 or F.65 occur, indicating issues with the activation of the gas valve or the temperature of the electronics.

How to check if ref. 130438 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- 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 that require diagnosis on the PCB 130438
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 doesn't light up at all, it's completely dead.
Cause: The transformer or the power supply stage of the PCB has stopped delivering current to the circuits.
Check the fuse on the PCB and if there is mains power before replacing it.
- 02
It locks with a fault code and cannot be reset from the unit itself.
Cause: The PCB keeps a safety lock active after detecting an anomaly.
Turn off the main power for a few minutes and check if the fault code reappears before replacing the PCB.
- 03
The domestic hot water is not reaching, but the heating is working.
Cause: The PCB is not giving the correct switching command to the domestic hot water circuit.
Check that the water flow properly activates the flow switch before assuming it's the PCB.
- 04
The boiler loses the configured parameters or resets itself.
Cause: There is a fault in the stabilized power supply of the PCB that causes microcontroller resets.
Check if the reset coincides with the use of other electrical appliances in the house, to rule out external power drops before replacing the PCB.
Vaillant fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 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. | This symptom may be related to the part, but it does not confirm that it is faulty. A technician must check the equipment and its inspection according to the manual before deciding on a repair or replacement. |
| 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.
