Rain Soft H2O softener will not operate/regenerate.

I have been reading many of the threads related to Rainsoft equipment before sending this and I would like to see if anyone has some type of an answer. I have a 7.5 year old Rainsoft water treatment system. I think it is an Amazon type from the pic's I have seen on this web area. I do not know if it is a "gold"model or not(I paid about $2200. for it back then). Anyway, the thing will not operate/regenerate manually or otherwise. I have tried the suggetions made by the H2O man in the threads and nothing seemed to work. I was able to get through to RainSoft and talk to a tech-unlike many other folks I have seen on this web site. After hearing my problem, he came to the conclusion that the piston was jammed from the sheer pin being busted or the motherboard was probably shot. He suggested getting a hold of my local dealer where I purchased it and have them look at and or repair it. He said it would need new O-rings, an ejector, a valve and the piston replaced. It seems like it will be very cosly considering labor and part costs. The Problem is my local dealer went belly up several years ago and the closest dealers are about 1to 1-1/2 hrs away. Out of four phone calls and voice mails left to them, no responses in two days whatsoever. I was wondering if parts are available anywhere or if maybe someone could assist me with the problem. I have followed H2O man's suggestions on some of the other threads and nothing has worked. I am able to check the capacity hardness and the other things on the LED screen and they are what they were originally set at. I have changed the battery, the fuse and let the computer reset as suggested, all to no avail. I does appear that the little piston seems to be stuck half way up, just speculating om my part. Any help/suggestions would be appreciated. By the way, Thank you H2O man for trying to assist all us problem children, you are indeed a good man and really seem knowledgeable about RainSoft equipment.
