Bosch Dishwasher E23 Error Code

If your Bosch dishwasher is displaying E23, this guide explains what it means,
what you can safely check, and when professional diagnosis may be needed.

What does E23 mean on a Bosch dishwasher?

Drain pump is blocked, clogged, or faulty.

Definitions can vary by model or platform, so compare the code with information for your exact model before replacing parts.

What you can try

Check for obvious drainage blockage. If the code remains, the drain pump may require service.

Before booking a repair

1. Confirm the displayed error code and your appliance model number.
2. Check relevant external issues such as a blocked filter, kinked hose, open door, interrupted power, or restricted airflow.
3. If a power reset is appropriate for the appliance, turn it off safely and restart it once.
4. If the code returns, avoid repeated resets and arrange diagnosis.

Safety note

Disconnect electrical power before accessing internal components.
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.
