Cleaning modes in water dispenser

A method for cleaning a water-dispensing device having a cold water tank, a fill valve for placing the cold water tank in selective communication with a water intake, a cold dispensing valve, a spigot in selective fluid communication with the cold water tank via the cold dispensing valve, an ozone generator, a drip tray positioned beneath the spigot and in fluid communication with a drain via a drain hose, and a controller, the method comprising:

• activating, by the controller, the ozone generator to ozonate water in the cold water tank;
• opening, by the controller, the cold dispensing valve to empty the cold water tank by dispensing the ozonated water from the cold water tank through the spigot and into the drip tray;
• and
• upon determining that the cold water tank is empty, opening, by the controller, the fill valve to refill the cold water tank.

A method for performing a fresh water cycling in a water-dispensing device having one or more water tanks, one or more fill valves for placing the one or more water tanks in selective communication with a water intake, one or more dispensing valves, a spigot in selective fluid communication with the one or more water tanks via one of the one or more dispensing valves, a drip tray positioned beneath the spigot and in fluid communication with a drain via a drain hose, and a controller, the method comprising:

• determining, by the controller, that a designated time for fresh water cycling for a designated one of the one or more water tanks has been reached;
• in response to determining that the designated time has been reached, opening, by the controller, one of the one or more dispense valves to dispense water from the designated one of the one or more water tanks through the spigot and into the drip tray;
• upon determining that a preset cycle condition has been reached, closing, by the controller, the one of the one or more dispense valves;
• and
• opening, by the controller, one of the one or more fill valves to refill the designated one of the one or more water tanks.
