1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Disconnect 230V electrical mains power before removing appliance side or rear panels.
  • !Ensure tub water or heating chamber has cooled below 30°C before unclipping thermistor probe.
  • !Use CAT III 600V/1000V insulated test probes when tng at PCB edge connectors.
3. Preliminary Mechanical & Visual Checks
  • Inspect sensor immersion sleeve for calcification, limescale scale, or thermal paste degradation.
  • Check wiring harness for pinch points, chafing against chassis metal, and terminal pin oxidation.
  • Verify probe is firmly seated in its rubber grommet or bracket inside the water/air circuit.
