Guide

How to check if reference 4516723 is the part for your boiler?

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

  1. Look at the motor label: it should say Wilo HB 15/7-3 and the number 4516723.
  2. Check the 3 speeds (0.27 A / 58 W, 0.40 A / 86 W, and 0.52 A / 118 W) and the 3.5 µF capacitor.
  3. Look for the Saunier Duval code engraved on your pump (0020016474 or, if it doesn't match, S10240, to be confirmed) and the exact model on your boiler's PCB.
  4. If your boiler is one of the four listed in the technical sheet, this pump has already been confirmed. If it is another one, please call us at 911 17 77 77 or write to us from Contact with photos of the pump and PCB.

Diagnosis and fault codes

Symptoms that require diagnosis in the Saunier Duval 4516723

Common symptoms and faults

  • 01

    The heating takes time to warm up or some radiator remains cold.

    Cause: Check the speed of the selector: I is the slowest. Also, make sure that the valves are open.

  • 02

    The pump does not start, especially after the summer.

    Cause: The rotor may be stuck after a long shutdown. A technician should check, with the boiler turned off, if the shaft rotates freely.

  • 03

    Moisture or dripping under the pump.

    Cause: Dry the area and check when cold if water comes out again from the joint of the motor or a 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.
