Symptom / Description

FAULT

The oven fails to reach the programmed temperature or does not heat at all, ultimately displaying code F6.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The PT1000 oven temperature sensor circuit is open. The control board does not receive any temperature readings and goes into default mode for safety reasons.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Unplug the oven. Locate the PT1000 probe. Inspect its connections for a broken wire or loose connector. Measure the resistance of the probe; if it is infinite, the probe is faulty and its replacement is imperative.

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.
