water on floor in front of fridge?

A puddle of water has appeared on the floor in front of my washing machine, I wiped it up and another puddle has formed, I dont think it is from inside the fridge, where could it be coming from.- the fridge was moved out yesterday from under the worktop when an engineer called as I had a loud clicking sound, he turned down the dial inside to no 2 and then the fridge was put back under the worktop
