Symptom / Description

FAULT

The device does not heat, overheats, or displays a temperature error, indicating a probe problem.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The temperature probe (NTC thermistor) is disconnected from the electronic card, its cable is damaged, or the probe is defective.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Turn off the device. 2. Locate the NTC probe, usually located near the heating element. 3. Check that its connector is firmly seated. 4. Test the wiring for continuity and measure the resistance of the probe with a multimeter (the value should be approximately 10-50 kΩ at room temperature). 5. Replace the NTC probe if defective.

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.
