The local pool company sold her a new capacitor as that is the most common cause of a pump not starting however i can t imagine a capacitor making a giant bang when it stops working so either they simply don t listen to their customers or they sell them things they don t need.
Pool pump not working.
The pool pump motor is not working or turning off while running.
Usually it s because of a bad thread sealant crack in the pump an air leak in the suction line a plumbing issues on the suction side of the pump or a leaky valve stem.
If your pump is not starting you ll want to check a couple of things.
Pump is not pumping water if the pump is not pumping water at all check that all suction and return valves are open and the pump lid is on tight with the lid o ring in place.
The easiest thing to do to fix this problem is to lift the skimmer lid take the filter out clean it and then replace it.
The capacitor is what starts the pump by giving it a jolt of electricity.
Air leaks disrupt the vacuum force of the pump and result in inadequate.
Pool pumps are supposed to be completely airtight.

If you neglect the skimmer filter and it gets clogged up the pressure in the water pump will drop.
You can also switch to running the pump at night when it s cooler or alternatively providing more shade.
When the pressure drops the pump cannot work efficiently resulting in a pool that gets dirty faster that it can be cleaned.
First check to see if the pump is getting power and check your timer to make sure the pump is on.
If the pump is on and you are hearing a humming noise it could be a bad capacitor.
This is what keeps them primed and sucking water properly.
So when they start sucking air that s a problem.
Check to see if something is inhibiting the fan in the bottom vents like leaves or mulch.
If your pool pump starts but then shuts off on its own moments later it s often due to overheating.
