I think you are digging a bigger hole for yourself. Firstly, the pump leaking would of been dripping on to ground not shorting out any electrics,. Secondly, if you killed the board it would be dead and not showing an error code, you would have nothing showing. Replacing the board is expensive and may be unnecessary. If you change it yourself then F&P will not give you any warranty so if you stuff that board you will be out of pocket. Suggest you contact your local service company if F&P is too expensive and ask them to come & diagnose the fault properly and replace only what is necessary. Just guessing and replacing parts at random is false economy. tell them you want a quote first.
