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 is completely dead, no lights or display, as if it is not receiving power.
Cause: The power supply stage of the PCB is not delivering current to the rest of the circuits.
Check the differential, the main fuse, and the fuse on the PCB before replacing it.
- 02
A different fault code appears each time it is reset, without a clear pattern.
Cause: The PCB misinterprets the signals from the sensors or fails intermittently in its internal electronics.
Disconnect and inspect the connectors on the PCB (oxidation, bent pins) before deeming it defective.
- 03
The boiler control is unresponsive, it doesn't change the temperature or the mode.
Cause: The microprocessor on the PCB has stopped managing communication with the remote control.
Check that the bus wiring between the control and the boiler is not loose or reversed before replacing the PCB.
- 04
The boiler ignites the burner but turns off after a few seconds, repeatedly.
Cause: The PCB cuts off the gas supply because it does not receive or properly process the flame signal or a safety sensor signal.
Check the ionization electrode and its wiring to the PCB before assuming the fault is with the electronics.
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.
