check your fridge!
I noticed water coming from under the fridge last night and it was still there this morning. DH pulled it out and found the tubing for the ice maker had a hole worn in it from vibrations and rubbing on a piece of metal . He fixed that and noticed some other connections were loose. It only ended up costing $7 to repair but we really saved finding those loose connections in other parts. Who knows what may have stopped working. My advice: pull it out, clean and tighted up any bolts or screws!
