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)
41Flow monitoring: the control detects an anomaly in the flow/return in the circuit.If the circulating pump does not start, is seized, or performs poorly, the flow rate drops and the electronics detect rapid temperature inversion/drift; check voltage at terminals, consumption/rotation, and bleed the circuit.
1TB Overtemperature: the boiler temperature limiter has activated due to excessive temperature.With the pump stopped, blocked, or with very low flow, the heat is not evacuated and the boiler triggers the TB; check the pump start/speed, shaft/rotor, and ensure the return is open.
6TW Overtemperature: the flow/return temperature has exceeded the safety threshold.Pump fault or low performance causes lack of circulation and overheating (TW); check that the pump is rotating and increase its speed/flow after bleeding and checking the bypass.
How do I know if this circulating pump is the one for my boiler?
Verify the reference 8601873 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.
