- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the circulator pump 122070370 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 radiators are not heating, although the boiler seems to ignite properly.
Cause: The pump rotor does not spin or spins very little, so the hot water does not circulate through the system.
Touch the pump while the boiler is running: if you don't feel any vibration, it is likely that the pump is not working.
- 02
There is a buzzing or noise coming from the boiler that seems to be coming from the pump.
Cause: The motor may be straining because the rotor is not spinning freely, or there may be trapped air in the pump.
Bleed the circuit before changing the pump, especially if you have recently refilled the system.
- 03
The pump is leaking water from the shaft.
Cause: The mechanical seal wears out over time and starts to allow water to pass through.
Dry the area and check after a while of operation if water is coming out of the shaft.
- 04
The pump does not start after the summer.
Cause: Lime and inactivity can block the rotor when the pump has been idle for months.
Before replacing it, try to move the shaft manually from the front screw, with the boiler cold and unplugged.
Fault codes for Baxi Roca that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 50-60-90 | The boiler shuts down due to overheating without the flame igniting. | If the circulation pump is not working properly or is blocked, it does not move the water and the boiler overheats. This causes the safety thermostat to shut down the boiler. To check it, bleed the water circuit and make sure that the pump shaft rotates freely. You can access the shaft from the front plug of the pump. |
| 50-60-70-90 | The boiler overheats with the flame on. | If the circulation pump is stuck or not moving enough water, the boiler will overheat even with the flame on. To check this, bleed the air from the circuit and verify that the pump shaft is turning. If it is blocked, you can try to move it with a screwdriver. |
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.
