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)
