Elaine H Raleigh , NC August 10, 2018 The old arms were clogged with food bits and as a result dishes would not be fully cleaned. Replaced all three rinse arms as they are not designed to be pulled apart, cleaned, and reassembled. It was very easy to switch them out, but do note that the parts don't come with the associated screws and washers, so save them from the arms you remove!
