Customer Questions and Answers for Center Spray Arm And Tube Assembly by Bosch

Hello Valerie, If you found debris in the spray arms you will most likely have to replace them since it is not possible to remove all debris from the inside of the spray arms. You should also remove the filter screens and open the sum assembly to expose the pump impeller to ensure no debris or damage is in the impeller area. Lastly, check for a clogged or restricted drain hose and make sure it is elevated to countertop level before connecting to the sink drain.
