Symptom / Description

FAULT

The program is interrupted due to an inconsistency detected between the water temperature sensors.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

One of the two water temperature sensors (the main or the safety one) has failed, providing an erroneous reading.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Unplug the appliance. 2. Professional intervention is required to access the sensors. 3. The technician will take measurements on both probes to identify and replace the defective part.

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.
