cleaned my skimmer and now it won't skim.

I have a coralife 65gal protein skimmer. I cleaned out the cup and dumped out the water in the canister part of the skimmer because I had to clean the crust of salt on the outside and inside the cup threads. Now after I put it all back together and in the aquarium and turned it on, now it isn't skimming or making any bubbles inside. So do I have wait for it to break in again or did I do something wrong?
