102 is Servos Off, you always get this on start up and you hit Reset and then Power Up/Restart to home the axes.
161 is X-Axis Drive Fault which can be cause by a short in the motor, or a short of one motor wire to ground, or running into a mechanical stop.
Did the X axis move at all?
If the answer is Yes then possibly it ran into a hard stop when it tried to home which suggests that the limit switch is stuck.
If the answer is No then it could be shorted wiring but that machine has brush type motors so it could be a short caused by a build up of carbon dust.
Either way you are going to have to start taking off covers to expose the limit switch and motor. Both the switch and dust build up causing a short are fairly simply to fix. A wiring short may also be easy, a true short in the motor means a new motor which starts running into more money.
