Vaillant PCB Control VMW 240 3 3 Ref. 0020092371
The Vaillant VMW 240 3 3 Control PCB Ref. 0020092371, manufactured by Vaillant, is responsible for controlling the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, become locked, or operate erratically, showing faults such as F.63, F.64, F.65, or F.67. This PCB is compatible with several models of the Turbotec Pro and Plus boiler range, as well as the Atmotec series. It is recommended to replace it when it shows signs of malfunction or error.

How to check if ref. 0020092371 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 0020092371. If it is not visible, do not identify the part by 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 0020092371 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 start in heating mode, but the domestic hot water works normally.
Cause: The heating and domestic hot water commands come from different outputs on the PCB; one can fail without affecting the other.
Confirm on the thermostat or control that the heating demand is actually reaching the boiler before replacing the PCB.
- 02
The circulation pump does not start when it should, and you notice the radiators are cold even though the boiler seems to be on.
Cause: The PCB sends the electrical signal to the pump through a relay; if that relay fails, the pump does not receive power even if it is functioning properly.
Measure with a multimeter if voltage is reaching the pump connector during demand, before blaming the PCB.
- 03
The remote control or the wall thermostat gets 'stuck', not updating the temperature or status.
Cause: The communication module of the PCB is what maintains the dialogue with the control; if it degrades, the control stops receiving data even though the boiler continues to operate.
Disconnect and reconnect the control unit to force a communication reset before replacing the PCB.
- 04
The boiler loses the time, the schedule program, or the settings every few days.
Cause: This data is stored in the memory of the PCB, backed up by an internal battery or capacitor that depletes over time.
Check if your model has a backup battery on the PCB and verify it before replacing the entire assembly.
Fault codes from Vaillant that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.63 | EEPROM error: the configuration/calibration memory of the electronics is damaged. | The EEPROM physically resides on this main PCB; when the documentation indicates 'electronic system fault', the cause is the PCB itself. Verify: the code persists after resetting and does not depend on any external component (valve, sensors); if it reappears, replace the PCB. |
| F.64 | Electronic system error / sensors: fault in the electronics or short circuit in the flow or return sensor. | The documented cause explicitly includes 'faulty electronic system' (the PCB). First, check the NTC flow/return sensors (resistance and connections); if the sensors and their wiring are correct and the fault persists, the origin is this board. |
| F.65 | Electronic system temperature too high: the electronics have overheated. | The temperature sensor is integrated into the PCB; the fault code is triggered by external overheating of the PCB or by a fault in the electronics itself. Check: rule out external heat sources or poor ventilation; if the location is correct and the issue persists, the PCB is defective. |
| F.67 | Flame control input signal out of limits (flame detection electronics). | The documented cause is 'electronic system fault': the flame detection/ionisation stage of the PCB delivers a signal out of range. First, check the ionisation electrode and its wiring; if they are correct and the signal remains out of limits, the fault is with this 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.
