Wilo Circulating Pump - Baxi Roca Laura 20/20 - Ref. 122270010
Wilo circulator pump (identified on the label as "System Wilo", under the Baxi Roca logo) that is used in the Baxi Roca Laura 20/20 boiler and other models from the Laura range, R30/30 and RS20/20F. It operates at three speeds and circulates water in the heating circuit. The replacement requires first confirming the fault of the part through technical diagnosis, even when it stops circulating water, makes noise, or the boiler loses heating.

How to check if ref. 122270010 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 122270010. 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 circulator pump 122270010
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 barely moves water or does not move anything for the heating.
Cause: The impeller of these three-speed pumps gets stuck with scale or accumulated sludge, which is common in older installations like the Laura.
Check with a flat screwdriver that the shaft rotates freely before replacing the entire pump.
- 02
A buzzing or vibrating sound is heard in the body of the pump.
Cause: It is almost always air in the circuit or a worn bearing due to years of use.
Bleed the radiators and boiler properly and test the three speeds before concluding that the pump is faulty.
- 03
The boiler ignites the burner but does not heat the house.
Cause: Without water circulation, the heat remains in the heat exchanger and the boiler can end up locking due to overheating.
Check that the speed selector is not in the minimum position and that the installation valves are open.
- 04
The pump works at one speed but not at the other two.
Cause: The selector or the winding of that specific speed may be damaged, which is common in Wilo/Baxi Roca units with years of use.
Manually test each position of the selector with the boiler cold to isolate whether the fault is with the selector or the motor.
Fault codes Baxi Roca that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 06 | Overtemperature clixon open without flame. | If the circulating pump is seized or not rotating, there is no circulation in the primary circuit and the boiler overheats before ignition; check by freeing the shaft through the front plug and verifying the voltage/consumption of the circulator. |
| 14 | Overtemperature clixon open with flame. | During operation, a pump fault/seizure prevents circulation and triggers the safety thermostat; check that the circulator is turning (screwdriver in plug) and that it is receiving power from the PCB. |
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.
