A water-dispensing device includes a cold water tank and a fill valve. The tank is in selective fluid communication with a water intake via the fill valve. The device further includes a cold dispensing valve, a spigot in selective fluid communication with the tank via the cold dispensing valve, an ozone generator in fluid communication with the tank, and a drip tray positioned beneath the spigot. The drip tray is in fluid communication with a drain via a drain hose. A controller is configured to perform a cleaning operation by: (i) activating the ozone generator to ozonate water stored in the tank, (ii) opening the cold dispensing valve to empty the tank by dispensing the ozonated water from the tank through the spigot and into the drip tray, and (iii) upon determining the tank is empty, opening the fill valve to refill the tank.
