Wilo RS15/5-3 Circulating Pump Motor - Fagor FE-30E/1B and Compatible Models - Ref. 4511885
Wilo RS15/5-3 circulator pump motor, identified by the factory label, for the indicated Fagor boilers. It operates at three speeds (2200, 2000, and 1600 min⁻¹) with powers of 84, 60, and 42 W and a capacitor of 2.6 µF, thermal class F. Two readings from the label (voltage and degree of protection) are uncertain due to blurriness.

How to check if ref. ST0005502 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 ST0005502. 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 ST0005502
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 burner ignites but the radiators do not heat or heat very little.
Cause: The pump does not move enough water through the circuit even though the boiler produces heat.
Check if the pump is spinning and vibrating when touched with the boiler running before declaring it faulty.
- 02
Noise or buzzing in the pump area
Cause: Worn bearing or trapped air in the circuit causes the motor to vibrate.
Bleed the heating circuit and see if the noise disappears.
- 03
The pump does not start or does not rotate, especially after a long period of inactivity.
Cause: The shaft has seized due to deposits accumulated during inactivity.
Try turning the shaft by hand with a screwdriver in the front slot before replacing it.
- 04
There is dripping or moisture appearing around the motor shaft.
Cause: The mechanical seal has lost its tightness.
Dry the area and check in cold if the humidity reappears right there and not in a nearby joint.
- 05
The pump buzzes and takes time to start, or starts with difficulty.
Cause: The start capacitor has lost capacity and the motor is not gaining momentum.
Check if the pump makes a prolonged buzzing sound before starting, indicating forced start.
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.
