Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
F.75Pump fault/lack of waterThe 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.23High differential temperature safety disconnectionA 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.24Safety lockout due to excessively rapid temperature increaseLack of circulation due to blocked/low-performance pump or air; check pump activation, flow-return ΔT, and correct bleeding/filling.
F.320The 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.321The 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.322The 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.323The 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.324The 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.325The 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.089The 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.
How do I know if this circulating pump is the one for my boiler?
Verify the reference 0010030632 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Grundfos piece.
What is it used for?
The circulating pump circulates the water through the heating circuit.
Noise, water not circulating, or cold radiators?
Typical symptoms: humming, seized rotor after a long stop, or radiators that do not heat evenly.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
Bleed the air from the circuit and the pump; check the pressure at 1–1.5 bar with the boiler cold.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
