i had that problem with mine and all i did was turned the pool off completely then put a high pressured nozzle on my hose, turned the water up as high as it can go so the water pressure from the garden hose is very strong then shove the hose/nozzle into the hole in the skimmer let it sit for about 15 min then take it out and turn the pool back on IT WORKED FOR ME lets hope it works for you.............. good luck
Had the same problem. Make sure you don't have any air leaks. My pump wasn't making a full seal so we had to keep priming with the hose to start. Good luck!
