What Does Error E09 Mean?

The Smeg Dishwasher E09 error code indicates a temperature-related fault, often linked to abnormal heating or overheating issues. This can result in the dishwasher stopping mid-cycle, displaying the E09 code, and potentially failing to heat water properly. Additionally, it may trigger the flood sensor if water is detected in the base tray, suggesting a possible leak or overfill situation. Addressing this issue promptly is essential to avoid further damage.

Common Symptoms:

  • Dishwasher stops mid‑cycle
  • Dishwasher displays E09 on digital display or LED pattern
  • Dishwasher may not heat water properly
  • Potential water detected in base tray/flood sensor triggered

Possible Causes

  • Abnormal water temperature detected (overtemperature) (medium)
  • Flood/safety float level triggered (possible leak or overfill) (low)

How to Fix Error E09

DIY Fix Initial safety and reset steps

  1. Turn off the dishwasher immediately and disconnect power at the mains.
  2. Check for any signs of water underneath the dishwasher or in the base.
  3. If accessible, look for blocked filters or obvious kinks in hoses that could affect water flow.
  4. Wait a few minutes then reconnect power and see if the code reappears.

Technician Only Technician diagnosis and repair for temperature control fault

  1. Access and inspect the dishwasher’s heating element and temperature sensor/NTC components.
  2. Check the wiring harness and connectors for the heater and temperature sensor for continuity and correct resistance.
  3. Measure temperature sensor response with a multimeter during a test cycle.
  4. Replace faulty temperature sensor, heater element, or control board components if confirmed defective.

Parts needed: Temperature sensor (NTC), Heating element, Control board wiring/connectors

🛑 When to Call a Pro:
  • If E09 persists after basic reset attempts.
