Bosch dishwasher auto open not working refers to a common issue where the auto open feature of a Bosch dishwasher fails to function as intended. The auto open feature is designed to automatically open the dishwasher door slightly at the end of the wash cycle to allow steam to escape, helping to dry the dishes more efficiently. However, when this feature is not working, the dishwasher door remains closed after the cycle is complete, and the dishes may not dry properly.

The auto open feature is a valuable function that contributes to the overall performance and convenience of a Bosch dishwasher.

Sometimes, the auto-open feature might not work due to an obstruction blocking the door. Follow these steps to ensure there’s no interference:

  • Open the dishwasher door fully and inspect the area around the door for any items or debris that might be blocking it from fully opening.
  • Remove any items that could be causing the obstruction, such as large utensils or dishes that might be impeding the door’s movement.

  • Unplug the dishwasher from the power outlet to ensure safety.

  • Using a standard small screwdriver or hook tool, gently push in on the little white tab of the door switch. You should hear a click, indicating the door lock has been activated.

The circulation pump and impeller are vital components that facilitate the auto-open feature. If the impeller is damaged or broken, it can hinder the dishwasher’s performance. Follow these steps to inspect the circulation pump and impeller:

  • After the test cycle, open the dishwasher and inspect the spray arms. If the dishes are not adequately cleaned, it may indicate an issue with the circulation pump or impeller.
  • Unplug the dishwasher once again to ensure safety while working on the internal components.
  • Carefully remove the dishwasher from the cabinet to gain better access to the circulation pump area.
  • Look for the impeller, which is attached to the circulation motor shaft. If it’s broken or detached, it will need to be replaced with an impeller kit.
