What does E03 mean on a Bosch refrigerator?
Dispenser user-interface fault.
Definitions can vary by model or platform, so compare the code with information for your exact model before replacing parts.
What you can try
Reset power at the breaker for 30 seconds. If the code returns, professional service is recommended.
Before booking a repair
- Confirm the displayed error code and your appliance model number.
- Check relevant external issues such as a blocked filter, kinked hose, open door, interrupted power, or restricted airflow.
- If a power reset is appropriate for the appliance, turn it off safely and restart it once.
- If the code returns, avoid repeated resets and arrange diagnosis.

Do not open sealed, gas, high-voltage, or refrigerant systems unless qualified to service them.
These steps are general guidance and do not replace service information for your exact model.
