Chaffoteaux Sime 2 23 PCB Ref. 61010047

When you open the tap or turn on the heating, the Chaffoteaux Sime 2 23 PCB (control board) Ref. 61010047 is responsible for controlling the ignition, the modulation of the burner, and the boiler pump. If this part fails, you may notice that the boiler does not start, gets locked, or operates erratically, displaying faults such as “Error Eeprom” or “Main P.C.B. error.” This board is compatible with several models, such as the Siam 2 23 E CF, Elexia CF B, and Nectra 1.23 CF, among others. A technician must confirm through diagnosis whether it needs to be replaced if you experience these issues, as its malfunction directly affects the operation of the boiler.

Guide

How to check if the ref. 61010047 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 61010047. 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 61010047

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 start at all: there is no display, no fan, and no ignition spark.

    Cause: This PCB distributes power to the other components; without it functioning, nothing receives current.

    First, check the fuse on the PCB and the 230V supply before replacing it.

  • 02

    The display lights up, but when requesting heating or hot water, nothing happens.

    Cause: The circuit of the PCB that manages the demand is not sending the order to the burner.

    Confirm that the tap or the thermostat are actually generating the demand before assuming it is the PCB.

  • 03

    Lockouts and resets occur frequently, without any noticeable external cause.

    Cause: An internal fault in the PCB causes it to misinterpret safety signals and block the boiler without a real reason.

    Note the exact lock code and compare it with the manual: if it is always the same, it may point to the component linked to that code and not to the PCB.

  • 04

    The boiler keeps losing its settings or resets to zero on the clock every little while.

    Cause: The memory circuit of the PCB that stores the configuration does not retain the data.

    Check if the PCB has a backup battery and if it is depleted before replacing the entire board.

Chaffoteaux fault codes that require diagnosis

CodeFaultTechnical checks
EEPROM errorEEPROM memory fault on the control board.This symptom may be related to the part, but it does not confirm that it is faulty. A technician must check the equipment and its inspection according to the manual before deciding on a repair or replacement.
Communication error between boiler PCB and user interface boardLoss of communication between the main PCB and the interface/user board.The PCB 61010047 does not establish/receive data via the bus with the interface; check connectors/wiring between the PCB and interface and the 5 V power supply. If they are correct, the fault is with the PCB.
Main PCB fault codeMain PCB fault.Internal fault of the PCB 61010047 (regulation/internal readings); after ruling out moisture/connectors and verifying service voltages, 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.
