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 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 system. According to the received signal, the nature of washing cycle is determined. According to this signal, the washing cycle can be a long or a shorter one. This process saves the amount of electricity consumed 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.
