Symptoms that require diagnosis in the circulator pump 122070270
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 vibrates or makes a loud noise when operating.
Cause: The impeller is rubbing or there is limescale buildup that unbalances it when rotating.
Change the speed on the pump selector and see if the noise changes.
- 02
The pump does not start after a period of inactivity, for example at the end of summer.
Cause: The shaft seizes due to sediment when the pump has been idle for months.
Manually unlock the shaft through the front slot of the motor before purchasing a new pump.
- 03
The radiators take a long time to heat up or remain lukewarm.
Cause: The pump does not provide the necessary flow to move the water throughout the circuit.
Make sure that the highest speed of the three is selected before declaring the pump faulty.
- 04
There is moisture or dripping at the base or shaft of the pump.
Cause: The mechanical seal has lost its tightness with use.
Dry the area and check if the humidity reappears after a heating cycle before replacing it.
Fault codes Baxi Roca that require diagnosis
| Code | Fault | Technical checks |
|---|---|---|
| 06 | Overtemperature open during ignition. | If the circulating pump is seized or not rotating, there is no flow upon start-up and the safety clixon opens due to immediate overheating; check 230 V at the pump on demand, release the shaft via the front screw, and bleed the system (≈1.2–1.5 bar). |
| 14 | Overtemperature open during operation. | With the pump faulty or blocked, heat is not evacuated from the heat exchanger and the thermal limiter opens during operation; check the rotation/consumption of the circulator, bleed, and confirm it is not seized. |
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.
