2016 SSV65 with 653 hrs. Used it about a month ago and everything worked fine. Now I get Error codes 10 and 11, (High-speed switching system, and Parking Brake System), and a Warning Light flashing. Park brake will not release and the light stays on when I push the switch. The bucket will tilt down a few inches but that's it. Arms don't move. When I engage the hydraulics, the light goes out but there's no typical little thunk. Seems like it used to make a slight thunk but not sure. I serviced the hydraulic fluid as it was low, (pretty low--hope I didn't break something), but it didn't change anything. After sitting for a few days the fluid level has dropped but can't find any leaks. Did I ruin a pump or something by letting fluid get too low? Or maybe a rodent chewed a wire? Anything else I can check or do before paying the dealer to haul it off? Thought about changing the filters or at least checking them. Only had the machine for about 60 hours so new to all of this. Sorry so long. Thx!
