How to check if the ref. 61002711 is the part for your boiler

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

Diagnosis and fault codes

Symptoms and faults that the PCB 61002711 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

    There is no spark or attempt to ignite; lock LED is on.

    Cause: Fault in the PCB or lack of power/blown fuse.

    Check the 230 V input, 2 A/250 V fuse, and ensure that the ignition module receives a signal from the PCB.

  • 02

    Spark is present but the gas valve does not open; there is no flame.

    Cause: Faulty gas relay/control on PCB or safety in open series.

    Check the continuity of the thermostat at 105 °C, smoke sensor at 80 °C, and minimum pressure switch; if they are OK and there is no control voltage, suspect the PCB.

  • 03

    Intermittent lockouts with a red LED and the need for a reset.

    Cause: Control fault on PCB or actual safety trip.

    Check probable causes (overheating/ventilation) and rule out hydraulic causes; if it persists without an external cause, PCB.

  • 04

    The pump works, but there is no ignition sequence.

    Cause: Logical fault of the PCB (TTL 200 I) or incoherent signal input.

    Check sensors, flow and pressure switch; if inputs are correct and it does not start the sequence, the PCB is faulty.

  • 05

    A 2 A fuse keeps blowing repeatedly.

    Cause: Short circuit on the PCB or on peripherals powered by it.

    Isolate loads (igniter, gas valve, pump) and measure consumption; if it continues to blow fuses with loads disconnected, 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.

Before purchasing
  • Work on the boiler without power and turn off the gas before intervening.
  • Download static electricity and avoid short circuits when handling the PCB.
  • The flue circuit and the safety thermostats are not bridged; their continuity is only checked.
  • Replace gaskets and single-use components after disassembly.
  • Check the tightness and evacuation of combustion products at the end.
  • Do not replace with 61002907 (model FF); it is not compatible with CF.
  • After the change, check the settings and the correct operation of ignition/ionization.
Frequently Asked Questions

Frequently asked questions about the PCB 61002711

Does this PCB work for the Siam FF?
No. The Siam FF (sealed chamber) uses a different main PCB (e.g., 61002907). This reference 61002711 is specific to Siam 23 CF (220421/220431).
Is it normal that my boiler does not display fault codes?
Yes. In the Siam 23 CF there are no numerical codes; the diagnosis relies on LEDs/lockouts and the verification of safety devices and signals.
How do I confirm that I have the 61002711?
Read the silkscreen on the PCB: “1 002 711 / TTL 200 I”. Cross-reference with the parts list of model SIAM CF 220421/220431; both point to ref. 61002711.
