Washer-dryer combo will not power on at all; no lights or display, but outlet has power.

Safety first: Unplug the unit and verify the wall outlet is properly grounded and not controlled by a wall switch.

• Check external power: Test the outlet with another appliance. Reset any tripped breakers or GFCI outlets.
• Inspect power cord: Examine the cord for cuts or burns. If damaged, replace the cord with an Avanti-approved part.
• Access line filter: Remove the rear or top panel to locate the line filter and internal fuse (if used). Check the fuse with a multimeter and replace only with the same rating if blown.
• Check internal connections: Ensure the power cord terminals are tight at the entry point and at the line filter and main board.
• Board-level issues: If fuses and wiring are good but there is still no power, the main control board's power supply may have failed and should be replaced by a technician.
