If they are using an HWH hydraulic slide system, you can check to be sure the manual valve on the manifold is fully closed. Each solenoid has a manual override. Turn them in (clockwise) to close. If you find they are all closed and still have this issue then the system is covered by a three year warranty. The solenoid will have to be replaced as teh fluid is leaking by and allowing the room to creep out. Good luck and keep us posted of the fix.
