Washer-dryer will not start a cycle; display shows E01 and door symbol may flash

Safety first: Unplug the washer-dryer combo from the mains and turn off the water supply before any work. Do not bypass the door lock for testing with the machine powered.

Step-by-step checks:

• 1. Inspect the door and latch: Open the door and check the plastic/metal latch hook on the door. If it is cracked, loose, or bent, the interlock may not engage. Gently close the door and confirm it closes firmly without play.
• 2. Clean the door catch area: Lint and detergent residue can prevent the latch from fully engaging. Wipe the door catch and the interlock opening on the cabinet with a damp cloth.
• 3. Access the door interlock: Remove the front door seal clamp (spring band) and peel back the gasket near the lock. Locate the door interlock assembly (typically a 3-wire device mounted with 2 screws). Check for signs of burning or cracking.
• 4. Check wiring: With power still disconnected, gently tug each connector to ensure it is firmly seated on the interlock and trace the harness back toward the main PCB for damage or pinched wires.
• 5. Test/replace the interlock: Using a multimeter, test continuity across the lock terminals when the latch is inserted (refer to the service diagram if available). If the lock does not change state or is open-circuit, replace the door lock assembly.
• 6. Control board check (advanced): If a known-good door lock and wiring are in place but E01 persists, the fault may be on the main control board. Visual inspection for burnt tracks or components can confirm, but replacement is usually required rather than repair.

When to call a technician: If you are not comfortable removing the front seal or testing live circuits, or if a new door lock does not clear E01, contact an authorized Ikea/Whirlpool service technician.
