Pressure Switch Air Manaut Minox Eco 24 E Ref. KI1267103
Biasi Minox includes the Biasi Minox Eco 24 E air pressure switch, which is responsible for monitoring the air pressure in the boiler and authorizing its operation. If this part fails, you will notice that the boiler does not start or gets locked, even if the actual pressure is correct, and it may display the fault code 05E: Smoke pressure switch anomaly. This pressure switch is compatible with models such as the Minox Eco 24 E, Minox 24 E, and Minox 28 E, among others. A technician should confirm through diagnosis whether it needs to be replaced when you experience starting or locking issues with the boiler.

How to check if ref. KI1267103 is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Find the reference printed on the installed part and check whether it matches the catalogue reference KI1267103. 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 that require diagnosis in the pressure switch KI1267103
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 start and the indicator shows a fault warning for flue or extraction.
Cause: The air pressure switch does not close the contact because it does not detect the minimum depression required to allow the gas to pass.
Before changing it, check that the flue gas outlet to the outside is clear and free of obstacles.
- 02
Every time the fault occurs, the unit needs to be reset manually for it to ignite again.
Cause: The air pressure lock requires a manual reset after each failed attempt; if it occurs frequently, the pressure switch is not closing stably.
Check the wiring connections of the pressure switch, ensuring that they are not loose or corroded.
- 03
The extractor is running normally, but the boiler remains locked without igniting the burner.
Cause: The pressure switch does not convert that rotation into a valid pressure signal, and the control board cuts off the gas as a precaution.
Check that the pressure connection pipes are not disconnected, crushed, or have accumulated condensation.
- 04
The fault mainly occurs with strong winds or when the flue is long.
Cause: External draft variations directly affect the reading of the pressure switch, which may remain at the limit of its setting.
Note if the fault coincides with windy days; if so, check the duct layout and outlet before the pressure switch itself.
Fault codes Manaut that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 05E | Flue pressure switch anomaly. | The air pressure switch does not switch with the depression generated by the fan (blocked pressure tubes/leak, misaligned diaphragm, or damaged contacts), and the PCB detects the incoherent state, causing 05E. Check with a differential manometer at the venturi that the nominal depression is reached and confirm with a multimeter the switching of the pressure switch and the tightness/cleanliness of the connections. |
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.
