Washer-dryer combo door will not unlock at end of cycle; E10 is displayed and clothes are trapped inside.

Safety first: Disconnect power before attempting manual door release. Ensure drum has stopped completely.

Step-by-step checks:

• 1. Wait for safety delay: Many Monogram combos have a short delay after cycle end before unlocking. Wait 2–5 minutes to see if the lock releases.
• 2. Perform a power reset: Turn off the breaker or unplug the unit for 5 minutes, then restore power and attempt to unlock the door using the control panel.
• 3. Use manual release (if equipped): Some models have a manual door lock release accessible behind the lower front panel or through the pump filter door. Pull the release tab or lever to mechanically unlock the door.
• 4. Inspect the door lock assembly: Once the door is open and power is disconnected, remove the door gasket clamp and access the door lock. Check for broken plastic parts or signs of overheating.
• 5. Test the lock electrically: Use a multimeter to check continuity of the lock and unlock solenoids and switches. Replace the OEM Monogram door lock assembly if readings are out of specification.
• 6. Check wiring and control: Verify the harness between the lock and main control board is intact and connectors are secure.

When to call a technician: If the lock and wiring are good but E10 persists, the main control board may be defective and should be serviced by a professional.
