How to check if the reference 122270090 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 122270090. 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 circulator pump 122270090 resolves.
The circulation pump circulates the water in the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The pump does not start or does not rotate when the boiler is turned on.
Cause: The shaft gets stuck due to limescale or because it has been idle for a long time, which is typical when resuming heating.
Try to free the shaft with a screwdriver through the central plug before replacing it.
- 02
A buzzing or strange noise is heard in the area of the pump.
Cause: It could be trapped air in the circuit or a bearing that is starting to fail.
Bleed the radiators and the pump's air vent before declaring it faulty.
- 03
The radiators are not heating even though the boiler is working.
Cause: If the pump does not circulate water, the heat does not transfer from the boiler to the circuit.
Touch the body of the pump while it is running: if it does not vibrate or is not hot, it indicates that it is not pumping.
- 04
The boiler shows a circulation error or a lack of flow fault.
Cause: The system detects that there is not enough water flow and blocks operation for safety reasons.
Check that the circuit shut-off valves are open before replacing the pump.
Fault codes for Baxi Roca that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 34 | No signal from the circulator to the control board. | The pump does not send the operating signal to the control board (internal fault of the circulator or defective wiring/connector); check power supply and signal at the circulator connector and continuity of the harness to the PCB. |
| 35 | Possible air in the system mixed with water in the circulator. | Air trapped in the pump causes cavitation and lack of flow; check by bleeding the circulator/installation and ensuring that noises disappear and return improves. |
| 36 | Possible circulator blockage. | Circulator rotor seized by lime/dirt prevents circulation; check that the pump receives voltage but does not rotate (humming), attempt mechanical unlocking via front plug and measure consumption/ΔT flow-return. |
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.
