I think you are saying that the pump pumps water.
One thing that can happen is that the start capacitor gets weak. The pump sometimes starts, sometimes it is delayed, and sometimes doesn't start.
When it is delayed or doesn't start, there is very high current that gets drawn. Once the pump starts, the current drops.
I am not saying that the start capacitor is getting weak, but that could explain the symptoms I think. It is cheaper than a new control box, and probably easier to change out.
Is your control box Franklin 282 301 8310 ? That uses a Franklin 275 464 137 start capacitor --
105-126 MFD (microfarads). start capacitor 126 search on an auction site gave what may be generic replacements. I am not sure of size matches.
If it means something to you, these are non-polarized electrolytics. They fail with accumulated time and starts. Guaranteed to fail eventually.
