I believe that the answer is indicated in the OPs post #10.
The batteries were low to begin with and attempts were repeatedly made to operate the jacks and slides, which further depleted the batteries, causing electrical components to fail.
I also believe that new solenoids were not needed, someone is either a bad troubleshooter or a good salesman, or both.
Agreed, solenoids refuse to operate under low voltage. Batteries forced to operate at low voltage heat up internally and destroy themselves, thats why I can speculate the whole issue is self inflicted. Low battery voltage.

HWH on the last 3 motorhomes. One stuck down and stranded me in a campground (not all bad). Replace at no cost.
Keeping the springs lubed up looks like the key.

Springs should never need lubing.
Some people lube the shafts of the ram, in the 10+ years we've had this MH I've never lubed the shafts either. In fact I've never even cleaned them.

I'm pretty sure the solenoid only opens a valve and the pump operates the jacks. If the battery is low, the pump would be running slow and the solenoids would have to be held operated longer to get the jacks to the desired height. This might burn out a solenoid, but I think it was bad diagnosis or one of those mechanics that just changes parts until he can find a bad one.

I have HWH jacks on my 2003 Newmar Kountry Star and never had any problems at all. 85000 miles of campgrounds and storage time. I suspect you may have a faulty installation causing your problems. If the installation is incorrect, you will have problems forever until the problems are fixed. HWH has great tech support, give them a call, you might be surprised..Good luck and seeya on the road.

Amen to that! HWH is the leading lever system used on motor homes for more than twenty years.

I understand this RV'ers frustration , i prefer the manual lever systems.

Recently I had also a problem with my HWH system. The first logical item that came to my mind was a faulty main relay.
The culprit was a 5A fuse in the electronic control box that the tech support at HWH told me to check.

My 20 year old HWH swing down jacks work great and the two problems I have had there eng dept. helped me troubleshoot the fault and repair them. Hwh is one company in the mh industry I give Hi marks.

Just a thought here. We have had HWH levelers on two previous coaches and lipperts on this one. The oly problem with the HWH is a slow retract due to me not keeping the piston lubed.
Since it is a pretty heavy pull on a battery when the leveling starts, it is a good idea to have the engine running when leveling. We popped a DC circuit breaker on this coach just after we got it, trying to level with the engine off. Now we level with the engine still running.
This may be part of what the OP was mentioning about the auxilary switch. Trying to run any heavy power user with a weak battery is not a real good idea.

Possibly the key to solving this problem is to always either have the engine running or be plugged into shore power before operating your jacks or slides. Doing this will assure you do not have low voltage.

Some HWH installations can not be operated without the key in the accessary mode, or when the engine is running or the shore line is hot the coach and chassis DC relays will not allow it to work. In particular that is how my Holiday is wired.

the pump motor draws 105 amps when leveling procedure starts. the valves require at least 9.5 volts to open. if the battery is low, or defective, the motor will run,but the valves will not open. you do have to have a good battery to operate the system.
that is not what caused the solenoid valves to fail. normally when a valve fails, it is because one jack has not fully retracted. the control box keeps opening the circuit to the valves in order to retract the jack. the repeated opening is what caused the valve (one valve)to fail. yes they get very hot when opened repeatedly.
these valves are wired in series parallel, ( see service manual for definition)and often the service tech replaces the wrong one. the easy way out for him is to replace all the solenoids, and that fixes the symptom, not the problem. the offending cylinder also needs to be replaced.
a good reading of the complete service manual will help to understand the operation and repair of your system. if you need further assistance, please feel free to email me at azpete@att.net

it mis NOT because your hear a "click" that the solenoids are defective by-the -way.
also be carefull, there are two types of solenoids. One is for intemitent (INT)use and the second Continuous (CONT).
May be you should also check what tyoe is the right one to use. A local HWH dealer tried recently to get rid of is INT solenoid despite I told him the right one needed (main relay)
Finally a 5A fuse solved my problem
