Ferroli Econcept TOP 35A Main Control PCB DBM05B Ref. 39829093

Stock · 1 unit

The main control PCB of the Ferroli Econcept TOP 35A DBM05B manages the ignition, burner modulation, pump, and safety features of the boiler. If it malfunctions, the user will notice that the boiler does not start, locks out, or behaves erratically, potentially displaying the fault code A02: flame signal present with burner off. This part is compatible with several models in the Econcept range, such as the Econcept Top 25A, Econcept ST 25, and Econcept Kombi ST 35, among others. It should be replaced when these symptoms or operational faults are detected.

Guide

How to check if the part number 39829093 is the correct one for your boiler.

What determines it is not the boiler model, but the reference printed on the part you already have installed.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference 39829093. 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 and faults that the PCB 39829093 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 boiler shows no signs of life, neither display nor pilot light.

    Cause: The electronic control does not send current to the rest of the boiler.

    Check that there is mains voltage and inspect the visible fuse on the PCB before replacing it.

  • 02

    The display shows a fault code and the boiler does not start.

    Cause: The PCB blocks the ignition when it detects an incorrect reading from any sensor.

    Note the code and first check the element it indicates, such as a sensor or a pressure switch, before declaring the PCB faulty.

  • 03

    The remote control or the thermostat has no effect on the boiler.

    Cause: The PCB does not process the demand order it receives from the regulator.

    Check the connection of the bus or the thermostat cable before replacing the PCB.

  • 04

    The boiler turns on and off by itself for no apparent reason, repeatedly.

    Cause: A component of the PCB intermittently loses continuity.

    Check if the fault occurs more when cold or hot; this is useful information to confirm the origin on the PCB.

Fault codes for Ferroli that this part resolves.

CodeFaultDiagnosis and solution
A02Flame signal present with burner offThe main PCB (DBM05B) may give a false ionisation reading or have a leak/short circuit in its detection stage, indicating a flame with the burner off; verify by measuring the ionisation signal/current on the board, checking the electrode wiring, and if the A02 persists with the electrode isolated, test/replace 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.
