Hi, I've enjoyed reading the rebuild posts for my model as I believe I am due a possible rebuild of the control valve assembly (not sure if you can tell from picture, but bottom piston assembly looks to be leaking as it's discolored). However, this post relates to the Mechanical Timer. I am trying to understand why the timer gets to the point of starting the regen cycle, but then doesn't. I have had to physically turn it clockwise to get it to kick on. Any help is appreciated. Thank you!
