Main Control PCB Vaillant Ecotec Plus VMW ES 236 3 5 Ref. 0020132764
Main Control PCB Vaillant Ecotec Plus VMW ES 236 3 5 Ref. 0020132764. This control PCB manages the ignition, burner modulation, pump, and safety features of the boiler. When it fails, the boiler may not start, lock out, or behave erratically, 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 model VMW 226/3-3 and VMW 236/3-5, among others. It should be replaced when it shows operational faults or system errors.

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 is completely off, with no display or indicators, even though there is power in the house.
Cause: The PCB controls the power supply to the entire boiler; if it fails, no current reaches the other components.
Check the main fuse of the installation and the one for the PCB before considering the PCB as lost.
- 02
A different fault code appears each time, or the same error comes and goes without a pattern.
Cause: The sensor and pressure switch reading circuits on the PCB are intermittently failing and generating errors that do not correspond to a real fault.
Note the codes that appear and compare them with the manual: if they indicate different parts each time, suspect the PCB.
- 03
The boiler does not respond to the thermostat or the remote control, although they seem to be working.
Cause: The communication module integrated into the PCB stops understanding the commands it receives.
First, check that the wiring or the connection of the thermostat to the boiler is properly done.
- 04
Every time the fuse is replaced, it blows again shortly after turning on the boiler.
Cause: A damaged component within the PCB causes a short circuit that repeatedly blows the fuse.
Do not replace the fuse more than once: if it blows again, it is a clear sign of an internal fault in 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.
