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)
E9The STB has been activated.If the circulating pump is blocked or has no flow, the primary overheats and triggers the safety limiter (STB); check by powering the Grundfos UPS 15-60 RLE, confirming rotation/consumption and bleeding the circuit to remove air.
AAExcessive temperature difference between the heating flow circuit and the domestic hot water.A stopped/blocked pump causes a large ΔT between flow and DHW; check start-up in test mode, flow through bypass, and ensure the rotor is not jammed and there is no air in the system.
