How to check if ref. 0010030632 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 0010030632. 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 0010030632 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 turns on and seems to work fine, but the heating does not heat or heats very little.
Cause: The pump is not circulating the water in the circuit even though the boiler is generating heat.
Check if the radiators furthest from the boiler are cold while the closer ones are heating; this is a typical indication of lack of circulation.
- 02
A buzzing or rattling noise is heard in the pump when the heating starts.
Cause: It usually comes from trapped air in the circuit or a rotor that rubs due to wear.
Bleed the air from the circuit through the radiators before considering that the pump is faulty.
- 03
The pump does not rotate, is seized, or stops shortly after starting.
Cause: Limescale deposits accumulate on the rotor when the pump remains inactive for extended periods.
With the cold installation, try to manually free the shaft using the central screw before replacing the pump.
- 04
Moisture or dripping appears in the area of the pump motor shaft.
Cause: The mechanical seal has worn out and no longer properly seals the shaft passage.
Confirm that the water is coming from the pump body and not from a pipe joint right next to it before purchasing.
Fault codes from Vaillant that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| F.75 | Pump fault/lack of water | The UPM3 does not generate the expected pressure increase during the self-check; verify by forcing the pump test (P.0) and checking that it rotates and that the pressure sensor registers Δp. |
| F.23 | High differential temperature safety disconnection | A blocked pump or low flow rate causes an excessive difference between flow and return; check the pump's rotation/rpm and ΔT, and review circulation levels in diagnostics. |
| F.24 | Safety lockout due to excessively rapid temperature increase | Lack of circulation due to blocked/low-performance pump or air; check pump activation, flow-return ΔT, and correct bleeding/filling. |
| F.320 | The heating pump is blocked. | The circulator rotor is jammed and not delivering flow; check by listening for a humming sound without circulation, perform pump test (T.001) and release or replace. |
| F.321 | The pump electronics are faulty. | The electronics of the UPM3 do not respond to the command (PWM/230 V) nor report rpm; check power supply/communication and replace if there is no response. |
| F.322 | The heating pump is overheating. | The circulator's electronics detect overheating (e.g., due to blockage/air); check bleeding and charging, casing temperature, and continuous operation. |
| F.323 | The heating pump is running dry. | The UPM3 has operated without water (air/insufficient priming) and does not generate flow; check filling and bleed, and replace if it has run dry. |
| F.324 | The electrical connection of the pumps has been interrupted. | Pump wiring/connector interrupted or harness damaged; check continuity and supply voltage to the pump and repair the harness. |
| F.325 | The heating pump has a fault. | General fault of the UPM3 (blockage or defective electronics); check with pump test and, if it does not respond or does not deliver flow, replace it. |
| F.089 | The integrated heating pump is not suitable for the appliance model. | A non-approved UPM3 has been installed for that model and the electronics detect it; confirm by reference/diagnosis and install the correct ref. |
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.
