Bosch Dishwasher Error Code E06 – How to Fix it Yourself

When there are issues with the Aqua Sensor of the Bosch Dishwasher, it displays the error code E06. The Aqua Sensor is basically a detector that measures the turbidity of the water.


The turbidity of the water determines how much the water is foggy or cloudy, which is caused by the individual particles present in the water.

So, the Aqua Sensor tests the water and sends a signal to the dishwasher. Based on that signal, your Bosch dishwasher determines the washing cycle.

This process saves electricity and it can also check whether the water can be used again or not.

Bear in mind that the malfunctioning of the control module can also lead to the display of the error code E06. In that case, you have to call a professional.

First of all, I’d recommend resetting your Bosch dishwasher.

As in every case, the first step that you must do to troubleshoot your Bosch dishwasher is to restart it.

If restarting your Bosch dishwasher does not help, then follow these steps:

  1. Take a look at the tank of the dishwasher and see whether it needs cleaning or not.
  2. Next, locate the Aqua Sensor at the bottom of the device, attached to the circulation pump. Take the left panel out, so you can easily access the Aqua Sensor.
  3. Clean the Aqua Sensor and then examine its connections. Clean them if it is required.
  4. Use a multimeter to test the sensor. In case of any issues, consider replacing it.
  5. If the error still persists, then the problem might have been caused due to the problematic control module. If that is the case, you contact Bosch support.

Hopefully, this guide helps you in getting rid of the error code E06 from your dishwasher.
