What Does Error E3 Mean?

The Ilve dishwasher E3 error code indicates a heating circuit failure, where the dishwasher fills but fails to heat the water during the wash cycle, resulting in longer cycle times and cold water. This is often due to a faulty heating element, malfunctioning temperature sensor, or wiring issues in the heating circuit.

Common Symptoms:

  • Dishwasher fills normally but wash cycle takes longer than usual
  • Water does not heat up during the wash
  • Cycle ends with an E3 error code on display

Possible Causes

  • Faulty heating circuit (heater element failure) (medium)
  • Temperature sensor (NTC) malfunction or fault (medium)
  • Wiring or connection fault in the heating circuit (medium)
  • Defective heater relay or control board component (low)

How to Fix Error E3

DIY Fix Check basic symptoms and reset power

  1. Turn off the dishwasher and disconnect power at the mains.
  2. Wait 1–2 minutes and restore power to see if E3 clears.
  3. During a cycle, stop mid‑cycle to check if water feels cold (use caution).

Technician Only Inspect and test heating circuit components

  1. Disconnect mains supply and open access panels to heater area.
  2. Test resistance of heater element and NTC temperature sensor using a multimeter.
  3. Inspect and repair/replace any damaged wiring or connectors in heating circuit.
  4. If heater and sensor are OK, test heater relay and related control board outputs.

Parts needed: Flow‑through heater / heating element, NTC temperature sensor, Control board / heater relay, Wiring harness and connectors

🛑 When to Call a Pro:
  • If you are uncomfortable accessing internal wiring or handling electrical components.
  • If multimeter tests show ambiguous results and the issue persists after replacing heater and sensor.
