Air Pressure Switch Baxi Roca Victoria 20 20 Huba Control Ref. 122161690
The air pressure switch Roca Baxi Victoria 20 20 Huba Control monitors the air pressure and authorizes the operation of the boiler. When it fails, the boiler may not start or may lock out, even if the actual pressure is correct. Users may experience fault codes such as 60-80-90, which indicate insufficient pressure, or 40-50-80-90 and 19, which signal pressure above zero. This pressure switch is compatible with several models from the Roca/Baxi Victoria 20/20 range, among others. It should be replaced when starting or locking issues are noticed in the boiler.

How to check if ref. 122161690 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 122161690. 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 122161690 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: the fan starts but stops quickly.
Cause: The pressure switch measures the depression of the extractor and, if it does not detect it, prevents ignition.
Make sure the fan spins smoothly and without any strange noises before checking the pressure switch.
- 02
The boiler keeps locking out and needs to be reset several times a day.
Cause: If the pressure switch does not switch properly, each ignition attempt may fail, even though the rest of the boiler operates well.
Check the pressure intake pipes: make sure they are not damaged, fallen, or have condensation.
- 03
The problem started after cleaning the flue or the siphon.
Cause: Any manipulation of the flue system can leave a pipe improperly positioned, which prevents the pressure switch from reading the pressure correctly.
Check the pipe connections after any intervention in the duct before replacing the part.
Fault codes for Baxi Roca that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 60-80-90 | Insufficient pressure in the pressure switch or flue thermostat. | The air differential pressure switch does not close with the fan running (lack of depression/obstruction or fatigued diaphragm). Check that the tubes are crossed and clean, the operation of the extractor, and that the microcontact closes by applying slight depression while measuring continuity. |
| 40-50-80-90 | Pressure above zero in the pressure switch or flue thermostat. | The pressure switch appears closed at rest (membrane/micro stuck, tubes inverted or with condensates). Check that the contact is open with the boiler off, clean/dry connections and confirm switching by applying slight pressure/vacuum and measuring continuity. |
| 19 | Pressure above zero in the pressure switch or flue thermostat. | In boards with display (R/RS/Victoria FF family), the pressure switch remains "closed" without demand. Verify that the micro is open at rest, correctly check/invert the pneumatic connections, and rule out water/obstructions in the tubes. |
| 20 | Insufficient pressure in the pressure switch or flue thermostat. | On boards with a display, the pressure switch does not close when the fan starts (lack of draft/obstruction or pressure switch out of adjustment). Check the extractor, flue duct, and electrical closure of the pressure switch when generating depression; inspect crossed tubes and tightness. |
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.
