Possible Causes

Blown mains fuse, Faulty power cord, Defective mains filter (EMI filter), Faulty main control board power supply

Safety: Ensure the wall socket is switched off before inspection.

Check outlet: Test the wall socket with another appliance to confirm power is present.
Inspect plug and cord: Look for damage or overheating. Replace if necessary.
Check mains filter: Access the mains filter where the power cord enters the machine. Look for burn marks and test continuity. Replace if faulty.
PCB power section: If power reaches the PCB but the machine remains dead, the board's power supply is likely defective and the PCB must be replaced.
