How to check if ref. 0010034152 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 0010034152. 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 and faults that the circulation pump 0010034152 resolves.
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 boiler ignites and the burner works, but the radiators do not heat properly.
Cause: The pump is not moving the water with sufficient flow and the heat is not reaching the radiators.
Check that the pump is not stopped or rotating very slowly; touch it while it's running to feel the normal vibration.
- 02
A buzzing or metallic noise is heard in the pump.
Cause: The impeller is rubbing, there is air in the circuit, or the bearing is worn out.
Bleed the air from the circuit and the pump before assuming that the part is faulty.
- 03
The pump does not start and seems to be stuck, especially if it has been idle for a long time.
Cause: The shaft has become stuck due to limescale deposits or lack of use.
With the boiler turned off and cold, try to manually turn the motor shaft through the front slot before replacing the pump.
- 04
Water or moisture appears at the base of the pump, or it drips from underneath.
Cause: The mechanical seal of the shaft has lost its tightness and is allowing water to pass through.
Dry the area well and check when cold if humidity reappears on the body of the pump and not at a nearby joint.
Fault codes from Saunier Duval that this spare part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F5 | Overheating of the primary circuit (temperature lockout). | The circulating pump (Grundfos ref. 0010034152) blocked or with no flow does not move the water and the boiler trips due to temperature; check that it receives 230 V on demand and that the shaft rotates/unlocks through the front cap, bleeding the circuit if necessary. |
| F14 | Heating flow temperature >95 ºC (limiter activated/overheating). | Fault or low performance of the circulating pump causes lack of circulation and rapid temperature rise; check the pump's start-up and consumption, ΔT flow-return, and if it does not rotate, replace/unblock it. |
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.
