Huba Control Air Pressure Switch Chaffoteaux Alixia 24 FF Ref. 65104671
If your boiler does not start or gets blocked despite the pressure being correct, you may need the Huba Control air pressure switch for the Baxi Roca Alixia 24 FF. This part is responsible for monitoring the pressure and authorizing the operation of the boiler. When it fails, you may experience faults such as 6 07, 6 08, 6 P1, or 6 P2, which indicate authorization issues in the system. It is installed in models such as the Alixia 24 FF, Pigma 25 FF, Talia 25 FF, among others. I recommend replacing it when you observe these symptoms to avoid further problems.

How to check if the ref. 65104671-01 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.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 65104671-01. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the pressure switch 65104671-01 resolves.
The pressure switch controls the air or water pressure to authorize operation. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite and locks up when trying to start.
Cause: The pressure switch does not detect the minimum depression of the extractor, so the control board does not allow the gas to pass.
Check that the fan rotates freely and that the pressure tube connections are properly fitted before replacing the pressure switch.
- 02
The display shows a fault warning for flue or smoke extraction.
Cause: It is the message displayed by the control unit when the pressure switch does not confirm the combustion pressure signal, whether from the pressure switch itself or not.
Note whether the warning appears consistently or only during certain startups; if it is intermittent, suspect the pipes or the terminal before the pressure switch.
- 03
The ignitions are intermittent: sometimes it ignites and other times it locks without apparent reason.
Cause: A faulty contact or a small leak in the pressure pipes can provide an unstable signal to the pressure switch.
Check for any cracks or loose connections in the silicone tubes; a small leak can cause intermittent faults.
- 04
The fault worsens with strong wind outside.
Cause: A gust of air at the outlet terminal can temporarily alter the back pressure in the duct and cause the pressure switch to not maintain stable contact.
Check the position and protection of the flue terminal against the wind before considering that the pressure switch is functioning properly.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 6 07 | Authorization of the flue pressure switch preceding the ignition sequence. | The air pressure switch is closed at rest (stuck contact or tubes incorrectly connected), which is why the PCB detects it before powering the fan; check the continuity of the pressure switch at rest (it should be open) and inspect the position/condition of the tubes. |
| 6 08 | Lack of authorization from the flue pressure switch with the fan on. | With the fan running, the pressure switch does not close because it does not reach the differential (membrane fatigued or connections/tubes obstructed/inverted); check that it closes at ~50 Pa by applying vacuum and measuring continuity during start-up. |
| 6 P1 | Delay in the authorization of the flue pressure switch. | The pressure switch takes time to close (lazy diaphragm or condensate in the tube) and the authorization arrives late; check closing times with a manometer and continuity of the contact when the fan starts. |
| 6 P2 | Flue Pressure Opening. | The pressure switch opens during the cycle (unstable contact or pressure drop), losing the authorization; check continuity under load with the fan active and inspect hoses/venturi for blockages/condensates. |
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.
