I decided to order the siphon break kit (siphon break, washer and clamp included), a new hose, and clamp (for the bottom hose connection) as the hose was original and well over 15 years old. I probably could have used the old clamp, but decided to get a new one in case there were problems with the old during removal. The video provided by A.P.P was helpful in giving confidence this was a task that could be done by myself. As was shown in the video, the hose connection to the siphon break had a band of metal for the clamp, which had to be cut off. This also influenced my decision to purchase a new hose. Having access to the front and rear of the washer was probably the most annoying part of the task as washers are often in place with the back to a wall between other obstacles. Note that there will likely be water spillage when the hose is removed at the bottom connection. My washer is now back in service.
