Hermann Supermaster S SE PCB Ref. 0020076179

If your boiler does not start, locks up, or exhibits erratic behavior, a technical diagnosis must confirm if you need the Hermann Supermaster S SE PCB, Ref. 0020076179. This control board manages the ignition, burner modulation, pump, and safety features of the boiler. When it fails, you may observe fault codes such as 13, which indicates a fault in the printed circuit, or 11, which signals a lack of reception by the main board. It is compatible with models from the MASTER, SUPERMASTER, SUPERMICRA, and THEMA ranges, such as the INOX 24 SE, 24 SE ECOPLUS, and 28 E, among others. Replacement requires first confirming the fault of the part through technical diagnosis, even when it shows operational failures or errors in the system.

Guide

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.

  1. 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.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

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 won't start and no indicator lights are on.

    Cause: The PCB is not receiving power, so no component can operate.

    Check that the boiler has mains voltage and inspect the fuse before replacing the PCB.

  • 02

    The boiler intermittently loses power, turns off, and then comes back on by itself.

    Cause: A fault in the power supply to the PCB causes an unstable supply.

    Check that the input cables are properly tightened in the terminal block before replacing the PCB.

  • 03

    The burner does not start even though you can hear that the pump and the fan are working.

    Cause: The PCB does not send the ignition signal to the ignition system, although the rest of the circuit is functioning.

    Check the ignition electrode and its wiring before declaring the PCB faulty.

  • 04

    A fault code appears that repeats every time a reset is attempted.

    Cause: The PCB detects the same anomaly in the circuit it monitors and locks the boiler.

    Write down the exact code and check the component it points to before replacing the PCB.

Hermann fault codes that require diagnosis

CodeFaultTechnical checks
13Main 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.
11No 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.
