When the tops die .

When the top of the plant (that which is above the ground) starts to wilt and die it is time to dig  up your potatoes. Just make sure they aren't wilting from lack of water before youdig them up.

It will need to be a very large pot, the roots get larger than the mature plant.

after they flower.
