Washer-dryer combo shows E30; often indicates a door or lock-related issue in some Asko firmware versions.

Safety: Always disconnect power before adjusting hinges or locks.

• Check closure: Close the door firmly until you hear a positive click. Avoid slamming.
• Inspect hinge and strike: Look for sagging door, loose hinge screws, or a bent door strike. Tighten hinge screws and adjust door alignment so it mates squarely with the lock.
• Test lock switch: If E30 persists, access the door lock assembly and test the switch for continuity when the door is closed. Replace the lock if defective.
