Bosch SHE53C85N 24 in 300 Series Front Control 46 dBA E6 Error Fix: Aqua Sensor Defective

The Aqua Sensor (turbidity sensor) is defective. The Aqua Sensor measures the clarity of the wash water to determine soil level and whether additional rinsing is needed. Check the sensor wire harness connections. Clean the sensor lens if coated with grease or food film. Replace the Aqua Sensor if it is not reading properly. A defective Aqua Sensor can cause excessively long cycles, poor cleaning performance, or unnecessary extra rinses.
