You will have to find the source of the water leaking into the base . First thing i would check , seeing as the machine has recently been moved , is the cold water inlet hose connection at the back to see if that is leaking. If it hasn't been fitted tight enough , it can leak and the water drips from the hose connection onto a small ledge which then runs into the appliance base.
If you want to empty the water from the base , MAKE SURE APPLIANCE IS UNPLUGGED and tilt it forward slightly. The water should run out onto the floor from under the front edge
