Safe checks, step by step

  1. 1

    Confirm that the appliance is a Bosch dishwasher

    No special tools

    Record the model number and confirm the display belongs to a dishwasher. Do not apply this page to a Bosch washing machine because Bosch documents E25 or F25 there as a turbidity-sensor fault.

    The same visible code can mean something different in another product type.

  2. 2

    Disconnect power and remove standing water

    No special tools

    Switch the dishwasher off and unplug it. Remove standing water with a sponge before opening the filter and pump-cover area described by Bosch.

    Keep the dishwasher disconnected while the pump area is open.

  3. 3

    Clean only the accessible pump area

    No special tools

    Remove the filter and pump cover using the model instructions. Remove only visible loose debris and verify that the cover is undamaged and locks back into position.

    Broken glass may be difficult to see. Wear suitable hand protection and never probe blindly.

  4. 4

    Inspect the visible drain hose path

    No special tools

    Without disconnecting inaccessible plumbing check that the visible hose is not sharply bent or crushed. If an accessible air gap is fitted inspect it only as its own instructions allow.

    Stop if the hose connection is fixed inaccessible or leaking.

For professionals only
