Vaillant Ecotec PRO VMW ES 226 3 3 Control PCB Ref. 0020132764
When you turn on the hot water tap, the Vaillant Ecotec PRO VMW ES 226 3 3 Control PCB Ref. 0020132764 is responsible for managing the ignition and modulation of the burner, as well as the pump and safety features of the boiler. If this part fails, you will notice that the boiler does not start, gets locked, or exhibits erratic behavior, displaying fault codes such as F.61, F.62, F.63, F.64, or F.65. It is compatible with boilers from the ecoTEC pro range, such as the VMW 226/3-3 and VMW 236/3-5 models, among others. It is recommended to replace it when you experience these symptoms to restore the normal operation of your system.

How to check if ref. 0020132764 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 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 and faults that the PCB 0020132764 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 never starts, nor does it attempt to ignite, even though it has power.
Cause: The PCB has a transformer that generates the control voltage; if it fails, there is no power for the rest of the components.
Check that the mounting bracket and the transformer connectors are not loose or making poor contact.
- 02
The boiler ignites the flame but turns off after a few seconds, repeating the attempt several times.
Cause: The PCB controls the flame safety time; if it fails, it cuts off the gas supply even if the flame is on.
Check the ionization electrode and its wiring before assuming that the fault is in the PCB.
- 03
Power cuts occur in the boiler that coincide with vibrations or impacts near the installation.
Cause: Being a more compact PCB, a poor contact in its mounting or connectors is more noticeable with vibration than in larger models.
Tighten the mounting bracket and check that no connector is loose before replacing the PCB.
- 04
The boiler works for heating but never provides domestic hot water, or vice versa.
Cause: The PCB manages which circuit to activate based on demand; a fault in that logic blocks one of the two modes without affecting the other.
Check that the demand for domestic hot water or heating is reaching the system properly before attributing the fault to the PCB.
Fault codes from Vaillant that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 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.
