The cork is stuck in the wine opener when I was trying to release the cork after the wine was opened

You need to replace the battery pack, pull it out and see what type of cells are used, then build a new battery pack, did this on my own opener and wow it really rocks, lots of power.

The black plastic ring is secured on the clear tube that you can see the corkscrew through with four little plastic snap tabs. I used a pair of channel locks to gently pull the ring off those tabs. Once you do that you have access to the inside of the clear tube and can reverse the corkscrew and get your broken cork out. Blow debris out and reassemble. Good as new! Even if you break one tab it should still hold, and if you break multiples use some super glue to hold it in place, that will be your last chance to fix it, but at least you've doubled the life of your toy. Good luck!

amazing that noone has answered this question including the people at Waring - I have no idea how to do this

A broken cork was stuck up inside my Waring Pro Wine Opener. Model WO50B. No amount of maneuvering could get it out. I removed the two small screws holding the silver part of the opener on. After that was off I could see two more screws and I removed those. The unit still would not come apart. I noticed that there were four oval shaped rubber plugs up on the black part of the unit. I pried the ovals out with a wooden skewer. That exposed the other four screws holding the long part of the unit together. Once I got those out, I gently pulled the two sides apart about an inch. I could have pulled it completely apart at that point (I think) but from there I was able to free the broken cork from the big internal cork screw. Everything screwed back together fine and the unit works again.

This is from Jen8926 in another forum and it worked for me (push up the inner sleeve an inch or more inside the main tube): Use a screwdriver (or whatever) to push the inner ring at the opening as far inside the appliance as you can. It is a black piece with a spring action that has plastic molded ridges inside. The ridges on the inner edge of this will grasp the cork. Then, while you are holding the inner section in place as far inside as possible, push the button to operate the opener and the cork should come out as it normally should. I had half a cork stuck up there, and this just worked perfectly.

We learned that NONE of these electric wine openers like the new "plastic" corks. Take a needle nosed plyers and hold the cork tightly(as it sits inside the housing) and gently push the button to release the cork. it should work.

We had the same problem, and we took the thing apart, unscrewed the cork from the corkscrew and put it back together. You have to make sure you line everything up properly inside, though. There are contact points that need to be lined up on the inside.
