Vaillant PCB VMW 226/3-3 Ref. 0020132764
Control PCB for Vaillant boilers VMW 226/3-3 and related models from the VM/VMW 3-3 and 3-5 range, with reference 0020132764. The circuit is printed with "Vaillant-Group", text that identifies the design of the board, not an external manufacturer of the component. It manages ignition, safety, and communication with the controls. Replacement requires first confirming the fault of the part through technical diagnosis, even when the boiler does not ignite or the board stops responding.

How to check if ref. 0020132764 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 0020132764. 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 0020132764
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 turns off by itself during operation and needs to be reset to start again.
Cause: An intermittent fault in the control board can cut off power to the safety components and force a lockout.
Check that it is not an intermittent power supply cut (power strip, socket) before replacing the PCB.
- 02
The display shows a specific fault related to electronics or the PCB, and it does not disappear after resetting.
Cause: The control board performs self-diagnosis and locks the boiler when it detects an internal fault that it cannot resolve.
Reset the boiler by cutting off the power for one minute; if the fault code reappears immediately, the PCB is likely faulty.
- 03
The connection with the room thermostat is lost and the boiler does not heat even though it is cold in the house.
Cause: If the communication module of the PCB fails, it does not receive the heating request from the thermostat.
Do not force, hit, or bridge the component. Request a technical check according to the equipment manual before deciding on its replacement.
- 04
The boiler does not ignite in any mode, neither heating nor domestic hot water.
Cause: A general fault in the PCB leaves both circuits of the boiler unmanaged at the same time.
Check that the mode selector of the boiler is not in the off or summer position before replacing the PCB.
Vaillant fault codes that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| F.61 | Fuel valve control fault | The PCB (0020132764) may fail at the control stage to the gas valve, so it does not send the correct signal/voltage and the valve assembly does not activate; check the voltage/signal from the connector on the PCB to the valve and the continuity of the harness. |
| F.62 | Fuel valve disconnection delay fault | The PCB electronics may unduly delay the closure of the gas valve (shutdown circuit), generating the fault; check that the PCB output/relay cuts off immediately upon flame loss and rule out a mechanical leak in the valve. |
| F.63 | EEPROM fault | Corruption or defect of the EEPROM integrated in the PCB; if after resets the code persists, confirm with diagnosis and replace/parameterize the PCB according to the manufacturer's procedure. |
| F.64 | Electronic fault/sensor | Fault in the analog/ADC circuit of the PCB that measures the NTC (flow/return); first check the NTC and wiring, and if they are correct, confirm a defect in the PCB electronics. |
| F.65 | Electronic temp. fault | Overheating/thermal damage in the PCB electronics; inspect the location and external heat sources and check the PCB (signs of heat, degraded components) and its ventilation. |
| F.67 | Electronic/flame fault | Fault in the flame detection circuit/ASIC of the PCB causing an implausible flame signal; check the grounding, ionisation electrode/cable, and if the signal is correct, the PCB electronics. |
| F.70 | Fault: invalid appliance code | After replacing the PCB, the DSN/appliance code does not match or the coding resistor is missing; verify and configure the DSN in d.93 or install the correct coding resistor for the new 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.
