1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Cut electrical mains power. Never measure resistance on energized heating circuits.
  • !Ensure tub water or heating cavity is completely drained and cool to the touch before dismantling.
  • !Verify absolute zero voltage using an approved 2-pole voltage detector before touching element terminals.
3. Preliminary Mechanical & Visual Checks
  • Inspect heating element tube for calcification buildup, bulging, pinholes, or blistering.
  • Check wiring spade terminals for heat discoloration, burnt insulation, or loose crimps.
  • On thermal Klixon switches: check for manual red reset buttons and verify spring-loaded snap action.
