Is the icemaker hose fastened securely to the water line repair line? Check also for any water spots on the floor, as these are typically clear signs of a water leak somewhere.
The first thing you need to do after leakage starts is to shut the water supply before you remove the faucet. You can either shut the valve in the sink or the main valve of your home.
