PCB Saunier Duval Hermann Renova Supermicra Ref. 0020076179
The Saunier Duval boilers from the Supermicra range use the Saunier Duval Hermann Renova Supermicra PCB, which is responsible for controlling the ignition, burner modulation, pump, and safety features of the boiler. When this part fails, the boiler may not start, become locked, or exhibit erratic operation, displaying fault codes such as 13 or 11. It is compatible with models such as Inox 24 SE, Inox 30 SE, 24 SE Ecoplus, among others. A technician must confirm through diagnosis whether it is necessary to replace it when these symptoms or faults are detected.

How to check if ref. 0020076179 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 0020076179. 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 that require diagnosis on the PCB 0020076179
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 does not ignite at all, not even the pilot light.
Cause: The transformer on the PCB does not supply the necessary current for the operation of the circuit.
Unplug the boiler and measure the continuity in the transformer before replacing the complete PCB.
- 02
The display or indicators are flashing with a code that is not in the manual.
Cause: An internal fault in the electronic control of the PCB causes incorrect readings.
Note the exact code and compare it with the instruction manual for your model before making the purchase; some flashes may indicate a problem in another component, not in the PCB.
- 03
The boiler starts but does not heat the water or the heating.
Cause: The PCB does not send the signal to open the gas valve, although the rest of the circuit works correctly.
Check that power is reaching the gas valve coil when you request heating; if it is not, the problem may be with the PCB.
- 04
It turns off and does not restart even if you press the reset button.
Cause: The control board gets stuck and cannot process the reset command.
Disconnect the boiler from the power supply for 30 seconds and try the reset again before considering that the PCB is faulty.
Fault codes Saunier Duval that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 13 | Main PCB fault. | The main PCB is faulty or has defective internal/external connections; check the fuse and voltages of the PCB (230/5 V supplies) and connectors. If the issue persists with correct wiring and peripherals, replace the PCB. |
| 11 | No reception from the main PCB (MMI line). | Communication fault towards the PCB (receiver/MMI input of the PCB) or the cable between interface and PCB; check continuity of the MMI lead and 5 V on the interface. If the fault persists with a good cable/panel, the PCB is the cause. |
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.
