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)
E1Outlet temperature > maximum service temperature.If the circulating pump (UPS 15-50) is seized/faulty, there is no flow, the flow pipe rises quickly, and the boiler locks out; check the bleed, turn the rotor through the front plug, and check the pump's power supply/wiring.
E2Return temperature > outlet temperature.The lack of circulation due to a blocked pump causes thermal inversion, and the control detects a hotter return; confirm that the UPS 15-50 starts upon demand, free the rotor, and check wiring/power supply.
E7Water pressure in boiler absent / incorrect pump operation.If the pump does not move water, the pressure switch/PCB interprets a lack of pressure/flow and locks; check the pressure gauge and leaks, unblock the rotor using the front screw and measure that the UPS 15-50 receives 230 V.
How do I know if this circulating pump is the one for my boiler?
Verify the reference MU1203100 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?
