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)
11Pump blockedThe circulating pump with bleeder (Ref. 05732500) is seized/stuck or filled with air, preventing circulation; the electronics detect the pump blockage and display 11. Check for the presence of 230 V in the pump and that the rotor spins/consumes; attempt to unblock using the front screw and bleed through the automatic bleeder.
How do I know if this pump is for my boiler?
Verify the reference 05732500 and ensure your model is on the list of compatible ones; compare connections and measurements. Install a Grundfos UP 15-60/SD pump.
Which models is it suitable for?
Pump shared by various models (see Compatibility). If your model does not appear, send us a photo and we will confirm it.
My boiler is making noise or the water isn't circulating, is it the pump?
Typical symptoms: noise or humming, seized rotor after a long stop, radiators not heating evenly, or shutdowns due to overheating. Check that the rotor turns and that the circuit bleeds properly.
Do you need to bleed it after changing it?
Yes. After installation, bleed the air from the circuit and the pump itself, and check the pressure at 1–1.5 bar with the boiler cold.
What pump does it exactly have?
Install a Grundfos UP 15-60/SD pump. Compare the body, connections, and connector with the original before installing.
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.
