Washer shows E18 and may stop with a door open indication mid-cycle.

Safety first: Disconnect power before adjusting door components.

• Inspect door strike and latch: Check for wear or looseness. Tighten mounting screws and replace worn parts.
• Check for excessive vibration: Ensure the washer is level and suspension components are in good condition. Excessive movement can cause the door switch to open momentarily.
• Test door switch: Use a multimeter to monitor continuity while gently moving the door. If the switch opens intermittently, replace the door lock assembly.
