Bosch Dishwasher Error code E11

Bosch dishwashers are known for their reliability and efficiency, but like all appliances, they can encounter issues. One common problem is the display of error codes, and in this article, we’ll focus on Bosch dishwasher Error Code E11. This error code typically points to a thermistor or temperature sensor fault, which can affect the dishwasher’s performance. We’ll provide a detailed explanation of the issue and steps to diagnose and potentially resolve it.

Understanding Bosch Dishwasher Error Code E11: Error Code E11 indicates a problem with the thermistor or temperature sensor in your Bosch dishwasher. The thermistor, often integrated into the heat pump on newer models, is responsible for measuring the temperature inside the dishwasher during various stages of the wash cycle. The NTC (Negative Temperature Coefficient) sensor, also known as the temperature sensor, plays a crucial role in monitoring and regulating the dishwasher’s temperature.

Diagnosing the Issue:

To determine the exact nature of the problem, you’ll need to perform a resistance check on the thermistor or NTC sensor. Consult your dishwasher’s tech sheet, often found inside the appliance, for the required resistance values specific to your model. Here’s how you can diagnose the issue:

1. Access the Tech Sheet: Open your Bosch dishwasher’s door and locate the tech sheet, which typically provides detailed instructions for diagnostic tests and component checks.
2. Find the Thermistor or NTC Sensor: Depending on your dishwasher model, you might need to access the heat pump to locate the thermistor. For older models, the NTC sensor is often found in the tub.
3. Measure Resistance: Use a multimeter to measure the resistance of the thermistor or NTC sensor. Compare the measured resistance with the values specified in the tech sheet.

Resolving the Issue:

If the resistance measured on the thermistor or NTC sensor does not align with the values in the tech sheet, it’s likely that the component is faulty and needs replacement. Here’s how you can proceed:

1. Order Replacement Parts: Identify the correct part number for the thermistor or NTC sensor in your Bosch dishwasher. You can find this information in your dishwasher’s user manual or by searching for your specific model online.
2. Disconnect Power: Before making any repairs, ensure that your dishwasher is completely disconnected from the power source for safety.
3. Replace the Faulty Component: Follow the manufacturer’s instructions to replace the faulty thermistor or NTC sensor. It’s advisable to seek professional assistance if you’re not comfortable with this task.
4. Test the Dishwasher: After replacing the component, restore power to your dishwasher and run a test cycle to ensure the issue is resolved.
