Jerry your thought of hiring an electrician is very good. In fact I would get him out there asap and explain what has happened. I would probabbly even sue the plumber.....and as some have mentioned, I would run conduit to the pump from the house......pvc is good and easy.
I would not pay for the pump and labor, by law you do not have to, since they mis diagnosed. They are still misdiognosing or saying something wrong. A broken ground wire will not cause the problem you had. The purpose of the ground wire is two fold. one is to protect from lightning, the other is to protect you from a getting shocked by touching the equipement if it has a fault and the case is HOT. It keeps you from being the path to ground. Maybe he was talking of the neutral, but I do not thinnk an open neutral would cause tripping of breaker. Some have mentioned a ground fault breaker, which should not be used in this case. Again A gfci breaker or plug is to protect the human, and would not work on a pump anyway. The purpose of the neutral is to carry an unbalance of load and to provide the 115 if needed...
Here are a copuple of links to read and prepare to argue with the plumber if needed.

Agreed, but the current / HP depends on whether the pump is 120 or 240 VAC. As you said just check the specs for the pump. An amprobe is a very useful tool, although not especially cheap. Just remember that it must go around ONE conductor ONLY, not the entire romex! We had a computer tech make that mistake on a large computer installation, and the engineers at corporate couldn’t understand how he got those small, erratic readings until I asked how he was making the measurement.
To the best of my knowledge, all submersible pumps capable of lifting water from 200' are 240 VAC.

Thanks and agree that an electrician needs to be involved in diagnosing this problem.

$6000 sounds like a LOT. I had a new well drilled 245 feet for $7000 and a new pump, controller, pad, control box, 480feet of 1 1/4 in pipe, wire, and a pressure tank, and all for $3900. and thats here in California..Total 10 grand

If they were installed at the same time, their lifetime may be up. I would be happy if the new wiring helped the new pump. Then you have no problems for awhile.

The cost of drilling a well depends on many factors:
* total depth
* diameter: 6", 8", 10" or larger casing
* whether it is cased to the bottom
* geology
* hydrology
* type of drilling rig (cable rig, rotary rig with mud, rotary rig with air
--ranging from very slow to very fast)
$7000 is very cheap for a 246 ft well. Was it a cable rig? How long ago?
That's about what my well cost....in 1972. Current estimate to replace
was $25,000 -- just for a hole cased to bottom.
Pumps currently available vary in quality. Our original pump had machined
brass impellars. The current pump (the one I put down) is a Grundfoss--
all stainless steel made in Sweden, but the impellers are just folded sheet metal.
Nothing is machined anymore.
