Solving Atena104M well pump problems
This customer called us for a damaged well pump:”The pump don’t run. The electrician, tested the pump and noticed a very high Intensity value. Maybe the pump got blocked with dirtiness and we can solve the problem cleaning it out?” she said.
Obviously not. Let’s go on site to check the situation out.
Looking at the cable that from the pump arrives to the control box, I understand that our damaged pump, has got an integrated capacitor. We probably have a damaged capacitor. If we run the pump, the diferencial switch, trips, so we also have a grounding problem… A plumber in this case, would recommend you to install a new pump. A submersible pump professional, bring the pump to his workshop to check if the motor, the cable or the capacitor is shorted to ground.

The first electrical test shows that the pump is shorted to ground:

Dismantling part2:
The capacitor don’t look like damaged at simple sight, but testing it with a special device we can see it has 15mf instead of 20mf so it is the cause of the starting problems and probably also the cause of the shorting to ground that we detected. Next step is to keep off capacitor and cable and repeat the insulation electrical test directly on the motor:
The test is good. The motor is in very good conditions so we can keep on repairing the pump.

During the water test, we can check the head of the pump and the Intensity. Everything is perfect.
The repaired pump can go back to its well.
