Samsung dishwasher is displaying an error code
Here's our reference list for dishwasher error codes, including troubleshooting steps to resolve them or links to the relevant guides.
The black rubber piece should be inserted behind the kick plate, and should be sandwiched between the fabric sound insulation and the kick plate.

Remove the screws, and then remove the kick plate from the dishwasher.

Press the flap back so that the flap's corner cutouts fit securely into place.

Confirm that the kick plate gasket is on the bottom of the kick plate, and then insert the screws to hold it in place.

For further assistance, contact a professional installer or refer to the installation guide for your dishwasher.
