THE FAUCET LEAKS HOT WATER
A little hot water leaking from the faucet from time to time is normal. Water increases in volume as it heats, so a small amount of water may drip from the faucet to relieve the pressure inside the water tank under the sink.
If the leak is continuous, though, the shut-off valve needs to be repaired. That usually requires the help of a qualified appliance repair technician.
