It really helps to have a schematic of the machine to see what exactly is hooked up to the breaker,this usually cuts your trouble shooting time to a tenth.
It would seem that there is something hooked up to the 115v line from the breaker that affects the hydraulic pressure. The breaker is usually after the i/o board so I would not expect that to be the problem, and if an output was shorted it usually just means that that particular ourput would be on all the time, which would only trip the breaker on a double acting valve. If you can identify all the items hooked up to the breaker and disconnect them one at a time to see which is causing the trip.
BTW you mentioned in your first post the breaker is rated at 5amps!
