What is the Turbidity Sensor?

The turbidity sensor is a small device located at the bottom of your dishwasher. Its role is to measure how much light passes through the water inside the appliance. If the water is dirty, the dishes won’t be cleaned properly, and the dishwasher might repeat the rinsing cycle over and over.

Steps to Resolve the E28 Error

Before you begin, remember the golden rule: Safety first! Ensure the appliance is disconnected from the power source before starting any repairs.

  1. Locate the Sensor:
    • You’ll need to remove the dishwasher’s base to find the turbidity sensor. It could be located in the sump or in the hoses at the machine’s base.
  2. Inspection:
    • Once you have access to the sensor, inspect it for residues or blockages that may be interfering with its operation.
  3. Cleaning or Replacement:
    • If you find dirt, clean it carefully. If the sensor is damaged or beyond simple cleaning, you’ll need to replace it.
  4. Test Your Dishwasher:
    • After cleaning or replacing the sensor, reassemble everything and connect your dishwasher. Run a test cycle to ensure the E28 error has been resolved.
