Machine shows E12 and may stop; often associated with very hot or very cold readings on the display that do not match actual water temperature.

Safety: Disconnect power and allow the machine to cool before touching sensors.

• Locate NTC sensor: On Wexiodisk dishwashers, the NTC is usually mounted in the wash tank wall or sump, or in the booster tank for rinse temperature.
• Inspect wiring: Check the sensor cable for cuts, crushed sections, or loose plugs at the control board.
• Measure resistance: Disconnect the sensor and measure its resistance at room temperature. Compare to the Wexiodisk service chart. A reading near 0 Ω (short) or infinite (open) indicates a failed sensor.
• Replace sensor: If faulty, install a genuine Wexiodisk NTC sensor of the correct value and reseal any grommets to prevent leaks.

Clear the error by cycling power and run a test cycle to confirm stable temperature readings.
