How to Clean a Water Dispenser

Due to health concerns, many households buy bottled water instead of drinking from the tap. They may pay a one time fee for the dispenser and refill the bottles as needed. Dispensers require very little maintenance. All you have to do is spend a few minutes cleaning it every 3 to 4 months before replacing the bottle.

  1. Unplug the cooler and remove the empty bottle.
  2. Drain all the water in the reservoir via the cold-water faucet. Fill the reservoir using tap water (approximately 1 gallon).
  3. Mix 1 tsp. bleach in 1 cup of tap water.
  4. Add mixture to the water already in the reservoir.
  5. Scrub the inside of the reservoir with a small brush and let stand for 5 minutes. Drain the water once again through the cold water faucet. Using a clean cloth, wipe dry the reservoir.
  6. Fill the reservoir with clean tap water once again and drain using the cold-water faucet. This should rinse off any bleach residue.
  7. Place a new bottle on the dispenser and plug in the unit. You're now ready to enjoy clean fresh water from your dispenser.
