Dryer display is completely dead; no lights or response when pressing buttons.

Safety first: Turn off the circuit breaker and unplug the dryer before opening any covers.

Restore power:

• Verify that the wall outlet has power by testing with another appliance.
• Inspect the power cord and plug for damage; replace if necessary.
• Access the mains terminal block and line filter; check for loose connections or burnt components.
• If accessible, test and replace any internal fuses with the exact specified type.
• If the dryer still shows no signs of life, the main control board’s power supply is likely defective and should be replaced by a technician.
