Had to loosen hose and drain off a little fluid because jack could not be pushed up by hand.. No more problem the rest of the trip. Question, it has a velocity valve/ check valve on each jack could that keep it from retracting all the way? Both rear jacks look the same retracted fronts are up all the way. Is there a way to adjust the system to allow the jacks to come up further?
The reason you had to loosen hose was because the solenoid to let the fluid out of the jack is on a timer. when your timer went off you were trying to push against the system and that system is what holds your motor home up. Next time you have to push by hand turn on the panel and hit retract jacks just before you try to push that should stop you from having to open a hose
