What Does Error E11 Mean?

The Smeg Dishwasher error E11 indicates a fault with the NTC temperature sensor, which can prevent the dishwasher from detecting water temperature accurately. This may lead to cycles ending prematurely or running indefinitely, along with unusual sounds or failure to drain water. It is crucial to check for loose or corroded connections and inspect the temperature sensor wiring for potential damage.

Common Symptoms:

  • Error E11 displayed on dishwasher panel
  • Cycle ends prematurely or runs indefinitely
  • Apparent failure to reach/monitor correct water temperature

Possible Causes

  • Faulty or open/shorted NTC temperature sensor (medium)
  • Loose or corroded sensor connector or damaged wiring harness (medium)

How to Fix Error E11

DIY Fix Basic checks for E11 error

  1. Turn off and unplug the dishwasher for safety.
  2. Check that the dishwasher door is fully closed and latch is secure.
  3. Inspect accessible wiring/connectors leading to the temperature sensor (if safe to access) to ensure they are seated and free of corrosion.
  4. Restart the dishwasher to see if error clears.

Technician Only Diagnose and repair temperature sensor circuit

  1. Disconnect power and locate the NTC temperature sensor in the sump or heater area.
  2. Measure the resistance of the NTC sensor with a multimeter and compare to the specified value for the model.
  3. Check continuity of wiring harness and condition of connectors.
  4. Replace the NTC sensor and/or repair wiring if readings are out of specification.
  5. Reassemble and test dishwasher cycles to confirm resolution.
