PCB Boiler VMW 32/362/3-5 Ref. 0020092371
If your boiler does not start, locks up, or exhibits erratic behavior, you may need the PCB boiler VMW 32/362/3-5 Ref. 0020092371. This control board manages the ignition, burner modulation, pump, and safety features of the boiler. The faults that may appear include F.63, F.64, F.65, and F.67, indicating issues with memory, the electronic system, or overheating. It is compatible with models such as VMW 242/4-3 M R1 and VMW 240/3-5 M, among others. It should be replaced when these malfunction symptoms occur.

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 ignites well when cold but fails when repeating the cycle several times in a row, for example by opening and closing taps.
Cause: A component of the PCB heats up with use and fails when hot, although it works well when cold.
Let the boiler cool down for 15-20 minutes and repeat the cycle to see if the fault is due to the overheating of the PCB.
- 02
There is no communication with the remote control or the modulating thermostat, and a bus fault code or similar appears.
Cause: The PCB is not transmitting or receiving correctly through the communication bus with the accessories.
Check the polarity and the condition of the bus wiring before assuming that the fault is in the PCB.
- 03
The boiler modulates the flame poorly: it jumps from minimum to maximum power suddenly, or it stays fixed at one level.
Cause: The PCB is not properly regulating the signal it sends to the modulating gas valve.
Observe the flame through the sight glass during a complete cycle and check if the fault is gradual or always the same before replacing the PCB.
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.
