Guide

How to check if ref. S1062000 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 S1062000. 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 S1062000

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 LCD screen does not display any digits even though the boiler is powered.

    Cause: The interface board controls the LCD screen; if it fails, the boiler may operate but does not display information.

    Check if the boiler ignites and heats normally even though the display is off. If so, the problem lies in the interface.

  • 02

    The rotary control does not change anything no matter how much you turn it.

    Cause: The rubber control activates an internal encoder; if it wears out or gets dirty, it turns but does not send the signal to the electronics.

    Clean the control shaft and test it slowly in both directions before replacing the PCB.

  • 03

    The screen flickers, turns off by itself, or displays incomplete digits.

    Cause: A loose connection between the interface board and the main board can cause interruptions in the power supply or video signal.

    Check the connector that joins both PCBs, as it may loosen due to vibrations.

Fault codes Saunier Duval that require diagnosis

CodeFaultTechnical checks
F5OverheatingThe boiler stops for safety reasons when it detects overheating. This can happen if the PCB is not functioning properly and does not accurately detect the temperature. Check the condition of the PCB, as a malfunction can cause this issue.

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.
