If there is water on the floor it is possible the machine detected a false leak and shut itself off precautionarily. Please check if your drip-tray needs to be emptied.
Troubleshooting beings with unplugging the machine and waiting 5 minutes. Then, plug back in and wait another 5 minutes before testing the dispense.
If this does not work please check and see if the valve is in the off position. Watch our tutorial on how to shut off your water.
