               ■  Remove the filter and feel inside the filter housing for anything caught that may be rattling.  


               ■  Clean the filter.

               ■  If the filter was loose or clogged, clean thoroughly and reassemble the filter making sure to secure it firmly.

               ■ Dishes may rattle during cycle under the pressure of the water or if the spray arms make contact   

                   with any items in the racks.

               ■ Rearrange dishes or adjust the upper rack to accommodate tall or large items.
