Washer-dryer shows E40; door symbol may flash; machine will not start

Safety: Ensure the door is closed before starting any cycle. Unplug before internal checks.

• Check for obstructions: Inspect the door gasket for clothing, coins, or debris preventing full closure.
• Close firmly: Push the door closed until you hear a positive click. Do not slam excessively.
• Inspect hinge and latch: Check that the door is level and not sagging. Tighten hinge screws. Inspect the latch hook for damage.
• Door lock inspection: If E40 persists, access the door interlock and check for damage or loose wiring. Replace the lock if necessary.
