Vaillant Turbotec PRO VMW 242/4-3M PCB Ref. 0020092371
Control PCB for Vaillant Turbotec PRO boilers and the VM/VMW/VU 240-282 range, in versions 3-3M to 4-5M. The copper filigree of the circuit itself, not a sticker, confirms it is manufactured by Vaillant Group, and it is silk-screened with the code TL-G1C next to the main capacitor. It is replaced when the control board stops functioning correctly.

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 respond at all: neither the display nor the indicator lights turn on.
Cause: The control board has experienced an internal fault and is not managing the system.
Check if there is power to the boiler and verify that the thermal cut-out has not tripped.
- 02
The fault code on the screen remains the same, even after resetting the boiler.
Cause: The PCB maintains the safety lock until the detected fault is resolved.
Check the code in the manual: there are faults related to the sensor or pressure switch that may display similar codes.
- 03
The remote control or the thermostat cannot activate the boiler, although it indicates demand.
Cause: The PCB does not process the signal from the regulator correctly.
Try bridging the demand directly at the terminals of the PCB to rule out the control.
- 04
The boiler turns off randomly, without showing any faults before the shutdown.
Cause: An intermittent fault on the PCB interrupts the cycle without leaving a trace.
Check the connectors and wiring of the PCB for possible loose connections.
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.
