What's Happening
The dishwasher's heating element or its circuit has failed. Water isn't being heated properly, resulting in poor cleaning and no sanitization. This is typically a heater or heating circuit failure, not a sensor issue.
How to Fix It
Reset power at the breaker for 30 seconds. If E09 returns, the heating element or its control circuit needs professional diagnosis and replacement. This is not user-serviceable on most Bosch models.
