Washer displays E40 and will not start; door symbol may flash.

Safety first: Do not slam the door; glass can break.

• Remove obstructions: Check for clothing or objects trapped between the door and gasket. Remove and close the door firmly until it clicks.
• Inspect gasket: Ensure the door seal is seated correctly and not folded or twisted, which can prevent full closure.
• Check hinge alignment: Gently lift the door to feel for excessive play. Tighten hinge screws if loose. If the door sags, adjust or replace the hinge.
• Examine latch hook: Replace the latch hook if it is bent, cracked, or worn so it no longer engages the lock fully.
