Since 'error 20' is an error on the travel motor, I took out the travel motor's PCB and found out that a few of the mosfets were busted.
I have tried to fix it by replacing a few of the busted FS70UM mosfets, and the unit worked for a few minutes, then something inside 'popped' off again after that.
I checked again, and this time it's a resistor, and still a few of the FS70UM mosfets.
I was thinking of changing the main fuse that leads from the travel motor to the travel motor PCB, to a lower value, so that if something's not right, nothing will 'pops off' in the travel motor PCB, instead will be the 'changed' fuse.
Is it possible and safe?
