Fagor Super Compact FE24E Circulating Pump - Wilo RS15/5-3 - Ref. 4511685
Wilo circulator pump (marked "System WILO") model RS15/5-3, originally installed in Fagor Super Compact FE24E boilers. It moves the water in the heating circuit. It operates at three speeds (2200, 2000, and 1600 min-1) according to demand. Replacement requires first confirming the fault of the part through technical diagnosis, even when it does not start, makes noise, leaks from the shaft, or the boiler stops heating due to lack of circulation.

How to check if ref. AS0015925 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 AS0015925. 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 AS0015925
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 remain cold or lukewarm even though the burner ignites and the boiler seems to be working.
Cause: The pump is not circulating water through the heating circuit, so the heat is not circulating.
Touch the supply and return pipes: if the supply is hot and the return is cold, the circulation is not working.
- 02
A buzzing or vibrating sound is heard in the pump area when starting the heating.
Cause: There may be air in the rotor chamber or the shaft forcing without fully rotating.
Change the speed with the selector: if the buzzing changes tone, the motor responds and it may just have air.
- 03
The pump does not start in any of the three speeds of the selector.
Cause: The rotor is locked or the winding does not respond at any speed.
Test the three positions one by one before discarding it: if none produce vibration, the fault is with the motor.
- 04
Water is leaking from the shaft or from the body of the pump.
Cause: The mechanical seal is worn out and allows water to pass through with use.
Dry the area and check after a while of operation if the drop reappears right at the axis and not at a nearby fitting.
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.
