Well water pump kicks on without running water in the house.

Without knowing all your variables with well it is hard to say. Bladder tank needs to have 30 psi with no water pressure. It is possible that the screen down the well is restricted and you are only getting that much water. Or you may have clogged impeller in pump.

For the water pump, that means the water pump needs replaced-the seal is shot when it drips out the "weep hole". The hole is there to let you know the inner seal is gone.

your pump should be just fine once the water starts flowing again. You may have run it too long without enough water to cool the seal.
If it is leaking water between the Jacuzzi Pump housing and the motor then you will need a new pump seal. Those are common pool parts.

either water lock or motor burnt out ,

I would put money on the thermostat as a first culprit. Water pumps usually fail in a leaking state rather than in a "not pumping water" state. In the current weather, there will be little harm in running without a thermostat to test it (or even longer if you want to). The thermostat is usually in a housing at the end of the top radiator hose. Unbolt the housing, pull the thermostat, make a new housing gasket out of a cereal packet and take a drive out.

If it works, go buy a new thermostat and gasket at your leisure.

pumps of this type will fail quickly without water. They are lubricated, and cooled by the fluid that runs through them.

I had this same problem and after having the repairman over to our house several times and having the circuit board changed, I figured it out on my own...

It turns out that the pressure created from the steam during the water heating stage (HO) was pushing on the door latch just enough to prevent the motor from running properly. Because the door wasn't latched completely, the water wouldn't drain and the dishwasher would go to the "Drying" cycle without ever pumping the water out of the basin.

I adjusted the levelling on the DW and that helped, but I'm still not sure that the problem is fixed. We may need a new latch assembly.

To test this, when the DW stops running at any time, push on the door. If the motor kicks back on, this is the problem.

Radiator Fan Control Relay Switch. I bet your electric fan doesn't run?

check the float. It probably needs an adjustment or cleaning.

remove kick plate from below the door. youll see a white tray behind the kick plate there is water in the tray activating a over flow switch. using a towel remove the water. this will solve the problem
