The bridge rectifier is not the only thing that can cause that fuse to blow. I have the same machine and it took me forever to figure out the F4 fuse was blowing because one of the bumper solenoid transistors was bad. I disconnected the solenoid lead running to the transistor and "voila!", no more fuse blowing. While working on the machine, I had another transistor similarly go bad to the extra chime and again, disconnecting the lead to the transistor stopped the fuse blowing problem. That is a 43v circuit and those SE9302 transistors are rated at 70 watts and 10 amps to operate those solenoids.
You indicated that the F1 fuse is blowing on your machine, so you're looking at the 5.4 VDC circuit and not the 43 v one. That circuit runs to the lights. You could have a shorted light circuit somewhere causing the problem. (Or, as suggested, it could be a bad bridge rectifier.) Output for 5.4v runs in two directions so I would start with disconnecting J1 and J3 on the board and see if it still blows the fuse. Then, if it does not, connect them back one at a time to see which circuit has the short.
I am old school on doing these repairs. I use a 100-watt light bulb connected in series with the machine plug so I can try various fixes to see if it stops the short without having to keep replacing fuses. If the bulb lights, then the short is still there. If not, then I am confident I found the shorted circuit and I plug the machine in directly and make sure the fuse does not blow with that circuit disconnected.
