Vaillant PCB VMW ES 32 362 3 5 Ref. 0020092371
The Vaillant VMW ES 32 362 3 5 PCB (control board) Ref. 0020092371 is a component that controls the ignition, burner modulation, pump, and safety features of the boiler. If it fails, the boiler may not start, become locked, or exhibit erratic behavior. This part is compatible with several models from the VM and VMW ranges, including the 240/3-5, 242/4-5, and 280/3-5, among others. A technician must confirm through diagnosis whether it needs to be replaced when there are operational issues affecting the boiler's performance.

How to check if it 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 —. 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 that require diagnosis on the PCB
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 turns off by itself during operation and does not display any fault code.
Cause: A relay or the microprocessor on the PCB is intermittently failing and cutting off the flame without blocking the system.
Check if the cut coincides with knocks or vibrations in the boiler: it points to a cold solder joint on the PCB.
- 02
The thermostat in the house is not able to make the boiler respond to temperature changes.
Cause: Communication between the PCB and the room thermostat has been lost.
Check that the communication bus connectors are not loose or corroded before replacing the PCB.
- 03
The boiler does not ignite and there are no lights or indications on the panel.
Cause: The PCB does not start the ignition sequence and the unit shows no signs of life.
Check the arrival of 230V at the input of the PCB and the condition of the internal fuse.
- 04
The boiler restarts by itself several times in a row, as if it is turning off and on in a loop.
Cause: The PCB loses power intermittently or resets due to an internal fault.
Check that the mains voltage is stable and that there is no condensed moisture on 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.
