Check all connections of the pressure pedal to make sure they are secure. There are two locations to check.
Stand the table on the ankle cushion to view the green control board.
Check the three wires (red,white,black) of the pedal cord where they connect to the main control board at "FOOT SW 1". Your view will look different because you will be looking straight up from the bottom of the base
The table can remain standing on the ankle cushion for this observation also. Check the other end of the pedal cord where it joins the pedal on the steel base. The photo shows the cross member at the foot end of the steel base.
