The upper spray arm is found above the top rack in your dishwasher. If your dishes are not properly cleaned after the cycle has finished, the spray arm may need to be replaced. As the part is made of plastic, it can crack or disintegrate over time. Replacing this OEM part is a simple repair that does not require any tools. Remove the rail stop clips from the top rack rails, and then remove the top rack from the dishwasher. With the rack out of the way you will be able to access the upper spray arm. Unthread the nut holding the spray arm to the ceiling of the dishwasher, and remove the damaged spray arm. Line up the new spray arm, and begin to thread the part onto the inlet tube. The nut should be firmly tightened so that there are no leaks, and the spray arm should be able to spin freely. The top rack can be placed back inside the dishwasher, and the rail stops reattached.
