The caps were a big help, along with the liquid form, we got "the dishwasher that came with the house" in good enough shape to continue to use until we find a replacement. They were very difficult to get onto the end of the dishwasher "prongs", that gives them staying power. I ended up inserting the tips of a small pair of needle nose pliers into the end of the caps and stretched them, they immediately snapped back to their former size once I had them in place.
