1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Disconnect 230V mains power before releasing door gasket clamp or lock retaining screws.
  • !Never short-circuit or bypass the safety door lock contacts: severe hazard of rotating drum exposure or fire.
  • !Keep fingers away from spring-loaded latch mechanisms during closure cycling.
3. Preliminary Mechanical & Visual Checks
  • Inspect door strike pin and handle latch hook for plastic deformation, breakage, or misalignment.
  • Check door hinge alignment: a sagging door prevents the latch tongue from engaging the safety microswitch.
  • Locate and verify emergency manual pull cord inside the lower drain pump hatch.
