Vaillant Turbotec VMW ES 242 3 5 M Display Module Ref. 0020056561
The Vaillant Turbotec VMW ES 242 3 5 M display module is a control PCB that manages key functions such as ignition, burner modulation, the pump, and the safety features of the boiler. When it fails, the boiler may not start, become locked, or exhibit erratic behavior. You may notice symptoms such as the fault code F.70, which indicates a fault due to an invalid appliance code. This module is compatible with several models from the ecoTEC Plus range, including the ecoTEC plus 415, 428, and 612, among others. It should be replaced when the boiler shows starting issues or unstable operation.

How to check if ref. 0020056561 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 0020056561. 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.
Symptoms and faults that the PCB 0020056561 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 display on the front panel does not turn on when starting the boiler.
Cause: The display module is not receiving power or is not communicating with the main PCB of the boiler.
Check that the unit has power and that no fuses have tripped on the main PCB before considering the screen as faulty.
- 02
The display does not show the temperature or pressure, although the boiler heats.
Cause: The display module may fail without affecting the operation of the boiler.
Confirm that hot water is coming out and that the heating circuit is functioning normally: if so, the fault is in the display.
- 03
The front panel appears off or with a very faint image.
Cause: A fault in the backlighting or in the module circuit can cause a dim image before it completely turns off.
Check if the problem worsens with the boiler cold or hot: faults that change with temperature are often due to a loose solder joint in the module.
Fault codes from Vaillant that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.70 | Fault: Invalid appliance code (DSN). | Replacing the display (0020056561) alone or together with the PCB without reprogramming the D.093 identification, or using a display not corresponding to the model, causes a mismatch of DSN/coding resistance. Verify by entering installer level and checking D.093 with the table in the manual and ensuring the display–PCB cable/connector and the display reference are correct. |
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.
