Korting C08

Korting error code C08 indicates: Körting KHI / KHC PowerBoost FlexInduction & HiLight Ceramic Hob: Diagnostic fault code C08 registered by the microcomputer controller. Induction cooktop mains supply low AC voltage (<185V AC) detected under power booster load.

The primary root cause for Korting code C08 is: On Körting domestic and cooking appliances engineered on Gorenje-Hisense platforms engineered with E.G.O. induction generator, 100 kΩ surface thermistors at 25°C, IGBT switches with thermal compound, 12V DC cooling fan, and touch slider UI: poor terminal contact resistance at cooktop connection block or undersized power cable (<2.5mm²). Metrological tolerance verification: mains voltage must remain above 207V AC RMS when two booster zones draw maximum 3700W each..

To resolve error code C08: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: tighten terminal block screws with torque screwdriver, verify 2.5mm² copper wiring and monitor line voltage with meter. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Disconnect electrical supply at the fuse board for 90 seconds. Restore power, touch and hold Key Lock for 5 seconds until acoustic signal indicates calibration reset.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Korting code C08 persists, the physical component causing On Körting domestic and cooking appliances engineered on Gorenje-Hisense platforms engineered with E.G.O. induction generator, 100 kΩ surface thermistors at 25°C, IGBT switches with thermal compound, 12V DC cooling fan, and touch slider UI: poor terminal contact resistance at cooktop connection block or undersized power cable (<2.5mm²). Metrological tolerance verification: mains voltage must remain above 207V AC RMS when two booster zones draw maximum 3700W each. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
