Vaillant Turbotec VMW ES 282 5 PCB Ref. 0020034604
La Placa Electrónica Vaillant Turbotec VMW ES 282 5 Ref. 0020034604 es un componente crucial que controla el encendido, la modulación del quemador, la bomba y las seguridades de la caldera. Si esta pieza falla, la caldera puede no arrancar, bloquearse o funcionar de manera errática, lo que puede generar errores como F.33 y F.36 relacionados con la evacuación de gas. Se monta en modelos de las gamas VMW, VM y VMI, incluyendo entre otros el VMW 282/2-5 y el VM 240/2-5. Un técnico debe confirmar mediante diagnóstico si procede sustituirla cuando se presenten estos problemas de funcionamiento.

How to check if ref. 0020034604 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 0020034604. 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.
Síntomas que requieren diagnóstico en la PCB electrónica 0020034604
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 shows no signs of life, neither the display nor any startup noise.
Cause: The PCB does not distribute electrical power to the other components.
Check the internal fuse of the PCB and verify the arrival of mains voltage before replacing it.
- 02
Ignition sparks occur but the boiler never ignites the burner.
Cause: The PCB does not send the gas opening command at the appropriate time after ignition.
Check the ignition electrode and its cable before assuming the fault is with the PCB.
- 03
The fault code displayed on the screen changes each time it is reset.
Cause: The internal electronics of the PCB intermittently fail to process the signals from the sensors.
Note each code that appears and check if it always matches the same sensor before changing the PCB.
- 04
The heating works but the domestic hot water does not come out hot, or vice versa.
Cause: The PCB does not manage the switching between the two circuits of the boiler properly.
First, check the three-way valve and its motor before blaming the PCB.
- 05
The boiler turns off by itself in the middle of use and needs to be reset to work again.
Cause: An internal fault in the PCB causes safety shutdowns without apparent cause in the rest of the circuit.
Check the grounding and ensure there is no moisture near the boiler before replacing the PCB.
Fault codes from Vaillant that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.33 | Gas evacuation fault | This code indicates a problem in the gas evacuation path. If the PCB is not functioning properly, it may not be managing the fan or the blockage in the flue correctly. Check the evacuation system and the PCB. |
| F.36 | Gas evacuation fault | This error indicates a fault in the gas flue path. If the PCB is not operational, it may not be properly managing the fan or detecting blockages. Check the flue system and the 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.
