Hi julio
The fault code 221 should have a T (traction) or L(hydraulics)before the code if it has a T then you have a voltage problem inside the controller.This fault will cut drive to creep speed.
The second code 280 is a hydraulic code and again is a low volage fault inside the controller.This fault will disable the hydraulics.
It looks like you will need to replace the control module in the cover behind the seat.
