To reattach a dishwasher spray arm, first inspect the central mounting hub and plastic retaining clip for any debris, food particles, or mineral scale. Align the center opening of the spray arm directly over the water supply feed port or mounting post. Push or twist the arm firmly downward until you hear a distinct click or feel the plastic retaining tabs lock securely into place. Always default to assuming a beginner-level approach and handle plastic parts gently to avoid snapping fragile locking clips. You can verify that the reinstallation was successful by spinning the spray arm freely by hand; it should rotate smoothly in a full circle without wobbling, sagging, or binding against the dish racks.
