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)
E52Internal error in the PCBThe PCB has an internal fault (hardware/firmware or signal management). Check 230 V and 5/12 V supplies, grounds, and connectors; if everything is correct and the error persists after reset, confirm by replacing/testing another PCB ref. 125569583.
E97Incorrect selection of the power supply frequency (Hz) for the PCBFrequency parameter 50/60 Hz incorrectly configured on the PCB itself (e.g., after changing the board or loading incorrect parameters). Check in the service menu the selection of 50 Hz for Spain or reprogram/parameterize the board correctly for the model.
E98Internal PCB faultInternal fault of the PCB (microcontroller/internal communication or logic). Check voltages and wiring; if peripherals are OK and the error reappears after reset, confirm with temporary replacement or reprogramming of the board.
E99Internal PCB faultCritical internal fault of the PCB (e.g., watchdog or communication between micros). Check power supplies and internal bus; if there are no external anomalies, confirm with cross-test/replacement of the PCB ref. 125569583.
