If the pot is higher than the pool, it will never fill to the top. Just fill it to the inlet level and it should be enough.

check the impeller for debris. you will have to take the metal band off that connects the wet end to the seal plate. inspect the impeller for debris. lube all o-rings and reassemble. if that does not work, investigate a blockage in the suction side plumbing.

My whisperflo wfk 3 has a leak from under the pump. How to repair it

you may have a crack in the pot housing, a leaking seal if the water is coming out under the motor( be very careful if so, shock hazard), or the drain plug at the bottom of the pot may be loose or broken. If you can isolate it to the strainer pot, then you may be able to replace just that. A leaking seal is tougher.

How to replace a Pentair dynamo strainer pot

I really would need a picture to be more accurate. If you have no way to hold the lid on to get suction, you have to replace the front bowl (pot) as that is where the strainer basket is and how the flow is created. That bowl (pot) unscrews from the front housing. You have to be able to free the suction pipe from the bowl and have enough room to spin the bowl off. You may also have to remove the pressure side pipe if you do not have enough room to turn the bowl (pot) off. If you can not get the bowl off of the front plate, you will have to replace the bowl and front plate all at once.

How to replace a Pentair dynamo strainer pot?

I believe the pot is screwed into the pump body/volute. Lift the complete pump enough to turn the entire pot counter clockwise, to unthread it off of the volute.

This site shows a separate part for the strainer body, but I'm not sure it is separate.
Call them with your model number and they can tell you if it unscrews and sell you the repair part that you need.
Worse case, you might have to see if you can remove the entire pump casing and purchase that.

The pot on my Dynamo pool pump tightens in the horizontal position instead of the vertical position.Any ideas on how to get it to tighten in the correct position.

I'm assuming you mean whe you thread the strainer basket pot into the pump and tighten it it ends up being 90 degrees off center? That means you cannot turn it and additional 270 degree. Unthread and wrap multiplul wraps of teflon tape onto threads. Then I'd add lightly add some pipe dope. Tighten the assembly up, but stop when it is snug and aligned. The combination tape and dope should keep it from leaking, but remember this would be a suction leak, so check carefully
