- 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 N47G003M5
The circulation pump circulates the water in the heating circuit. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
Hot water comes out when it should be heating, or vice versa; it seems that the circuits are mixing.
Cause: The three-way valve is not functioning properly and leaves both paths partially open.
Check if the valve has a manual control or lever and move it by hand to see if it switches freely before replacing the assembly.
- 02
Water leaks are appearing around the golden area of the bleed valve.
Cause: The automatic bleeder has a worn or dirty seat and does not seal properly.
Close the bleed valve cap a quarter turn and observe for a few minutes if the dripping stops before replacing the entire assembly.
- 03
There is noise or bubbling in the hydraulic group when heating.
Cause: Trapped air that the bleeder does not evacuate properly, or the pump rotor is rubbing due to accumulated scale.
Manually bleed the air by opening the bleed valve for a moment before declaring the pump faulty.
- 04
The water circulation is low and the heating does not reach the radiators properly.
Cause: The pump rotor spins slowly or the three-way valve gets stuck halfway and restricts the flow.
Check if the manual control of the gas valve moves smoothly and if the shaft of the pump rotates freely in its front slot.
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.
