I think part of the problem with burned out solenoids is leaving them on too long - the solenoids overheat. This happens when the jacks take too long to retract. At least that's what happened to me.
I didn't replace the solenoid myself - my system was still under warranty - but I don't think it's too hard. If you check the
HWH web site, there are manuals available under the blue bar that says "Customer Support & Technical Service." I read the instructions for replacing solenoids for my system back when I had one burned out, and I seem to remember a caution in the about the tip of the valve that can get stuck in the bore. I think the tech who replaced mine had that problem. He had to play around to try to get hold of it to get it out.
If you replace the solenoid yourself and loose hydraulic fluid and need to top off the reservoir, be sure to use HWH hydraulic fluid of Dexron transmission fluid.
DO NOT use hydraulic jack oil. Hydraulic jack oil may damage the seals and hoses in the system.
