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)
A 37CPU faultInternal CPU fault in the main PCB (EA FFI, ref. 952930). Check 230V/5V voltages and grounds; if everything is correct and the error reappears after reset, replace the PCB.
A 39PCB fault 1Self-diagnosis detects an internal fault in the main PCB. Check regulated 5V/12V and connectors; if the wiring/power supply is fine and the fault persists after reset, the PCB (952930) is damaged.
A 40PCB fault 2Second level internal fault in the main PCB. Check for stable voltages and continuity of connectors/bus; if everything is correct and the error returns, replace the PCB (952930).
E 37Problema de comunicación con la placa electrónica principalLoss of communication with the main PCB (display/interface ↔ main PCB). Check harness/cable T1, connectors U1 and 5V data; if the wiring is correct, the PCB (952930) is the probable cause.
