Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

  1. Check the PCB 0020183525 or 0020106661 and the designation PM-02, and compare them with your PCB.
  2. Compare the marked code next to it: 3512 0309 G with 0020183525, 1453 5079 G with 0020106661.
  3. Check that the relays and connectors match in number and position with those on your PCB.
  4. Do not confuse it with S1047000 (Themafast F 30 E H-MOD), 288.00.0008 (Thema NOx F24) or 0010028086 (Vaillant).
  5. If they match, call us at 911 17 77 77 with the model of your boiler.
Diagnosis and fault codes

Symptoms that require diagnosis in the Saunier Duval.

Common symptoms and faults

  • 01

    The boiler does not ignite, the burner does not start, it restarts by itself or shows meaningless errors.

    Cause: that does not turn on; adds resets and nonsensical errors. It is not an official table.

  • 02

    Temperature regulation faults or unexpected shutdowns.

    Cause: They are being cited.

  • 03

    Burnt components or traces or oxidation on the PCB.

    Cause: It quotes you.

  • 04

    The boiler does not ignite: the fault code F28 appears (ignition fault).

    Cause: Failed ignition: it could be gas, ignition, electrode, or PCB.

    Have a technician check it.

  • 05

    The boiler shuts down during operation and does not restart (fault code F29).

    Cause: Gas cut-off, flue gas recirculation, condensates, or faulty grounding.

    Have a technician check it.

  • 06

    The boiler does not ignite or turns off during operation and does not ignite again (fault codes F28 or F29).

    Cause: Ignition fault: it may be due to lack of gas, gas meter, ignition or PCB.

    Put the boiler out of service, wait 5 seconds, and then restart it. If the issue persists, have it checked by the official SAT.

  • 07

    The red pilot light is flashing and a fault code F followed by a number appears on the screen: the boiler stops due to an anomaly.

    Cause: The PCB has detected an anomaly. The number indicates which one: ignition, flue, sensors, or circulation.

    Reset it: turn off the boiler, wait 5 seconds, and turn it back on. If the fault persists, have it checked by the official technical service.

  • 08

    The boiler does not ignite: after several attempts, it shows a fault with F28 or F29.

    Cause: Ignition fault; the source mentions ignition or ionization electrodes.

    Check that the gas valve is open and reset once. If it fails again, have a technician check it.

Fault codes Saunier Duval that require diagnosis

CodeFaultTechnical checks
F00Return temperature sensor (NTC2) disconnected.Check if the sensor connector is loose. If it persists, have a technician check it: it could be the sensor, the cable, or the PCB.
F01Return temperature sensor (NTC5) disconnected.Just like the F00: check the connector and, if it persists, have a technician check it.
F27Flame detection fault: the flame control is not reliable.If it occurs when turning on or off, have a technician check it: it could be moisture in the electronics or the flame control.
F28Ignition fault: the burner does not ignite.If it repeats, have a technician check it: it could be the gas, the ignition, or the PCB.
F29Flame loss during operation.If it repeats, have a technician check it: it could be a gas cut-off, flue gas recirculation, or a faulty ground connection.
F61Gas valve activation fault.Have a technician check it: it could be the wiring of the gas valve, its coils, or the electronics.
F62The gas valve does not close in time after the flame goes out.Have a technician check it: the gas valve or the PCB are the suspects.
F15Flame detection fault: there is a flame with the burner off.If it occurs when turning off or on, have a technician check it: it points to the PCB or the flame control.
F5Fault of the heating flow sensor (NTC2).Check if the sensor connector is loose. If it persists, have a technician check it: it could be the sensor, the cable, or the PCB.
F1Ignition fault, possible gas supply issue (in Themafast C; in NOx it appears as F28 or F29).Put the boiler out of service, wait 5 seconds, and then restart it. If the issue persists, have a technician check it.
F20Overheating: the boiler protects itself from excessive heat.Have a technician check it: verify the circulation and the temperature limiter.

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.

Pending applications to verify
Saunier Duval THEMANOX F25 B1 — compatibility mentioned, pending validation by variant. commercial 2025–2026, PDF page 217: IDENTITY CONFLICT: assigns 0020135165 to Vaillant VM386/5-5R4 and VMW306/5-5 (art.288.60.0030). ThemanoxF25B1 and the photographed PCB PM-02/0020106661 are not confirmed. The reference field code needs resolution; do not use this match for price or compatibility.

Frequently Asked Questions

Frequently asked questions: Saunier Duval

Where is the code for the PM-02 PCB and which one should I compare?
On the PCB, it has 0020183525 (with 3512 0309 G) or 0020106661 (with 1453 5079 G), as well as PM-02. The 0020184123 is usually printed on the circuit or on a side sticker.
Is it compatible with my Thema NOx F25 B, Themafast NOx F30, or Micraplus NOx 24 B2?
Check the status of each model in the compatibility sections; the pending variants are not validated. Registered: for the Thema NOx F25 B1 and the Themafast NOx F30/B-2. Registered application for the Thema NOx F25 B; for the Themafast NOx F30 without version. Micraplus NOx 24 B2 and Themafast NOx F25 A: To be confirmed.
What is the difference between 0020183525, 0020184123, and 0020106661?
and they sell 0020184123 along with 0020183525. At least they sell 0020184123, among them. 0020106661 goes on the other PCB: just the list.
Are there different versions of this PCB with the same reference?
Yes. Please note that under the same reference there are different versions and ask to compare relays and connectors. It refers to 0020183525 with 4015 0075 G, different from our 3512 0309 G and 1453 5079 G.
Is it compatible with the Micraplus NOx 25, the Themaclassic 2, or the Thema NOx F24?
Check the status of each model in the compatibility sections; the pending variants are not validated. Micraplus NOx 25 and Themaclassic 2 have: to be confirmed. The Thema NOx F24 uses a different PCB according to (288.00.0008). Send us a photo of your PCB and boiler from Contact, or call 911 17 77 77.
What symptoms point to this PCB and who should install it?
the boiler does not ignite. It includes resets, nonsensical errors, and burnt components or clues, and does not advise installing it without prior experience (electrical and gas connections). Without experience, consult a qualified technician.
How to identify this PCB?
Compare the silkscreen, the distribution of the connectors, and the exact variant of the circuit with the photographs.
