Washer-dryer combo shows E17 and may not start; often related to door not closing or locking correctly.

Safety first: Unplug the appliance before adjusting hinges or replacing door components.

• Check door alignment: Close the door slowly and observe if it lines up evenly with the cabinet. Adjust hinge screws if the door is sagging.
• Inspect latch and strike: Look for wear or damage on the latch and strike. Replace worn parts.
• Door lock sensor: If the door appears to close properly but E17 persists, the door closed sensor inside the lock may be faulty. Replace the door lock assembly.
• Test operation: After adjustments and replacements, restore power and start a cycle to confirm the error is cleared.
