Symptoms and faults that the circulation pump 6135927 6281895 solves.
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 boiler takes a long time to heat the house even though the burner is working well.
Cause: The pump is not moving enough water, and the hot water is not reaching the radiators in time.
Check if the pump is warm and vibrating to the touch: if it is cold and not vibrating, it is not circulating.
- 02
There is a noticeable vibration or rattling noise in the hydraulic module.
Cause: The rotor may be rubbing while rotating or there is trapped air in the pump.
Bleed the air through the bleed screw of the pump before considering the replacement.
- 03
The pump does not start and there is no indication that it is turning, even though the boiler is requesting heating.
Cause: The shaft may be blocked, especially if the boiler has not been used for a long time.
Try to manually free the shaft with the central screw of the rotor, with the boiler disconnected.
- 04
The heating works intermittently: it heats up a bit and then stops by itself.
Cause: An irregular circulation due to a faulty pump causes the control board to shut down for safety.
Check that there is no air in the circuit and that the installation pressure is within its range before changing the pump.
Fault codes for Sime that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| ALL 09 | Water circulation anomaly (lack of circulation in the primary circuit). | If the circulating pump is faulty or blocked, the flow rate drops and the flow switch detects insufficient circulation, activating ALL 09; check the rotor rotation, power supply, and pump consumption. |
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.
