The servo motor which changes the resistance (under the plastic covers) is winding the cable in the wrong direction. Release tension on the cable by pulling the magnets away from the fly wheel and flip the cable off the the servo motor pulley, this will allow the cable to be pulled in the correct direction.
My treadmill has a little steel rod that flips in and holds the bed up' When you want the bed down you pull the rod back out and it lets it come back down.
Sounds like the overlay on the console has stopped working. If you get beeps on all buttons but not the ones in question, this will need replacing. It’s quite an easy job once you have the parts. Try eBay or the shop you got it from.
This is a situation the controller board motor is Faulty.
They controlled the console CPU BOARD. with 8-12VdC
