Washer-dryer combo will not power on; no lights or display

Safety first: Ensure your hands are dry and the area is not wet when working with mains power. Unplug the appliance before opening any panels.

• 1. Check outlet and fuse: Test the wall socket with another appliance. Check the household circuit breaker or fuse.
• 2. Inspect power cord: Look for cuts, burns, or crushed sections. Replace the cord if damaged.
• 3. Access mains filter: Remove the top cover and locate the mains interference filter where the power cord enters. Check for burn marks or bulging components. Replace if faulty.
• 4. Control board: If power reaches the board but the display remains dead, the internal power supply on the PCB may have failed. This typically requires replacement of the main control module by a professional.
