Washer-dryer combo displays E6 and will not start or stops mid-cycle; door may not lock properly.

Safety first: Always unplug the appliance before working on the door lock or front panel.

• Check door closure: Ensure the door closes firmly and the latch engages fully. Look for clothing caught in the door seal.
• Inspect door strike: Examine the plastic or metal door strike on the door. If it is cracked, bent, or loose, replace or tighten it.
• Test door lock: Remove the front panel or door seal clamp to access the door lock assembly. Check the wiring connector for a secure fit and no corrosion.
• Continuity test: With the lock removed and the unit unplugged, use a multimeter to test the lock contacts. If the lock does not change state when actuated, replace the door lock assembly.
• Reinstall and test: Refit the lock and door seal, restore power, and run a short cycle. If E6 persists after replacing the lock and verifying alignment, the main control board input circuit may be faulty and require professional service.
