Dryer will not start; display shows E01 and cycle will not begin when Start/Pause is pressed.

Safety first: Unplug the dryer from the mains before removing any panels. Do not bypass safety interlocks for normal use.

Step-by-step checks:

• Check door closure: Open and firmly close the door. Ensure no clothing is trapped around the latch area and that the door sits flush with the cabinet.
• Inspect the latch and strike: Examine the plastic/metal door catch on the door and the strike/receiver on the cabinet. If cracked, loose, or badly worn, replace the latch kit.
• Test the door interlock switch: Remove the top cover (usually rear screws) and front panel as needed to access the door lock assembly. With power disconnected, unplug the switch and test continuity across the correct terminals with the door closed using a multimeter. Replace the door interlock if it does not close electrically when the door is shut.
• Check wiring: Inspect the wiring harness from the door lock to the main control PCB for broken conductors, chafing at the hinge area, or burnt connectors. Repair or replace damaged wiring.
• Control board input: If the door lock tests good and wiring is intact, the door input circuit on the main control PCB may have failed. Visual inspection may show burnt tracks or components. Replacement of the main control PCB is usually required.

When to call a professional: If you are not comfortable testing live circuits or removing the front panel, or if the main PCB appears faulty, contact a qualified appliance technician.
