Guide

How to check if it is the part for your boiler

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

The motor label says "Grundfos UP 15-60/SD" (P/N 59716503).
Plate data: 230 V, 0.45 A, 110 W, capacitor 2.5 µF.
It is not the UP 15-40/SD (P/N 59714528), which is another pump.
Any questions? Send us a photo of the label and the PCB of your boiler from Contact.

Diagnosis and fault codes

Symptoms that require diagnosis in the Saunier Duval.

Common symptoms and faults

Noise or vibration in the pump body.
Cause: There may be air in the circuit: bleed the system until water comes out.
03
Air keeps entering even after you bleed the radiators.
Cause: Check the pump connections and the circuit pressure.
04
Water under the pump.
Cause: Locate whether it comes out of the axis or from the joints.
05
The pump does not start after the summer or only hums.
Cause: The rotor may be stuck.

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.
