How to clean a bottom loading water cooler

How to clean a bottom loading water cooler. Water Cooler Dispensers are convenient appliances that provide purified water directly at the point of use.

If yours is a bottom loading model, it’s constantly receiving filtered water delivered through the cooler tank at the top.

As water sits in this reservoir, sediment can settle out, leading to an unpleasant taste and odor when the dispenser is in use.

Cleaning your dispenser regularly is an easy task that can keep your home up and running with fresh-tasting drinking water for you and your family!

You shouldn’t be worried as we have discussed how to clean a bottom-loading water cooler in detail below.

How to clean a bottom loading water cooler

6 primary steps to clean a bottom loading water cooler

Here is our guide to clean a bottom loading water cooler:

1. Unplug the Water Cooler

Before you begin cleaning, make sure to unplug your water cooler.

This will ensure that no electric currents are present while handling the product, and there is no risk of getting shocked.

2. Remove the Bottles

Any bottles that are currently on the dispenser should be obliterated before beginning to clean.

If they aren’t removed, it becomes much harder to clean since the electrical components underneath need to be accessed for proper cleaning.

3. Clean Water & Bleach Solutions

Clean Water Bleach Solutions

Fill a bucket with equal parts of warm water and bleach solution (a capped total or two of bleach) and use this mixture to fill up your reservoir tank after removing it from your more excellent dispenser.

Allow this solution to sit in the tank for approximately 30 minutes. Then, remove the solution by dumping it back into the bucket and refilling it with clean water.

4. Empty & Rinse Your Reservoir Tank

After allowing your solution to sit in the reservoir tank for 30 minutes, empty this mixture by pouring it into your sink, then refill your tank with fresh water to rinse.

5. Clean Your Dispenser Outlets

Using a small brush or damp cloth, carefully scrub away any residue that may be present around the outlets of your dispenser where you insert each bottle.

If necessary, use a needle attached to an air compressor for hard-to-reach places. Be aware that compressed air can cause bacteria to disperse, so avoid blowing directly into or onto any ports that dispense water.

6. Replace the Reservoir Tank

Replace the Reservoir Tank

Once you have adequately rinsed your reservoir tank, replace it on your more excellent dispenser. Reattach all of the bottles to their proper places and plug them in your unit.

If desired, top off all bottles with water after cleaning to ensure that nothing has been left behind inside, which could alter the taste or quality of your drinking water.

Repeat as Needed

Depending on how often you use your dispenser will depend on how often you need to clean it. Generally speaking, you should at least rinse out the reservoir daily then follow these same steps every 2-4 weeks depending on use.

Also, be aware that areas with hard water may require more frequent maintenance than soft water since there is a higher concentration of minerals present that could build up over time.

Viola! You’re all finished and ready to enjoy fresh, clean, filtered water from your bottom loading water cooler dispenser again.

This is a relatively quick and easy job that can be completed in just a few minutes weekly. Repeat these steps after each use of your machine to keep it in excellent working order.
