CodeWhat does it mean?Cause and diagnosis (this part)
E0Fault in the control board/PCB (internal fault in the control electronics).The PCB does not pass the self-diagnosis (internal hardware/power or communication fault); check mains voltage, fuses, and connectors, and measure 5/12 V voltages on the board; if it persists after reset, the board is defective.
F0Internal fault (control unit/PCB error).Internal fault of the PCB (hardware/memory or moisture on the board) causing a lockout; check that the board is not damp or damaged, inspect connections and supply voltages; if not resolved, replace or repair the board.
