Water Dispenser Not Working

The main issue many people face when they buy a new water dispenser is that the water cooler dispenser is not working properly at all.


Check out that the switch of the water dispenser is plugged into the wall and the main source of electricity is on. It is very common for users to forget to check the electricity, so make sure to check out these little things. A customer stated his experience in the as follows:

“When it was delivered to my home and placed in the kitchen, I was checking it out by turning buttons on at the backside of the body but wouldn’t function. I came to realize that the main power button was not plugged in.”

Water Tastes Nasty

If your water tastes bad, it necessarily means that the water dispenser is unclean. Generally, you simply need to clean down the cooler.

There is a simple solution to this, rinse the inside of the water cooler carefully with clean boiled water, detergent, and a scrubber prior to filling it with any freshwater.

You should also check the water filter. It might be filled up with debris that may be the result of extra salts present in water. When water is heated, some extra salts are kept in the water cooler’s internal parts, causing a bad odor, which makes the water polluted.

Timely maintenance and regular cleaning can provide the best results in attaining fresh and lightweight water.

Water Cooler is Leaking

Why is my water cooler leaking? This is a common problem facing many people. There may be several reasons behind it. 

Generally, it happens due to the holes or maybe cracks in the water jug or the water cooler itself. The holes in the jug or cooler are caused normally when they are being transported. 

Secondly, when the air pressure of the jug changes, it may cause leaking. Now, if you want a solution, you need to check first from where the leak is coming. Here are some solutions to be followed when you are facing this issue: 


Things usually required for repairing the leaking issue:

  • Sandpaper, 120 grit
  • Plastic epoxy resin
  • Epoxy scattering device
  • Detergent
  • Scrubber

Instructions To Repair Cracks Of  the Water Cooler:

  1. If the epoxy patch is sited on the outer of the water cooler, you can apply a paint coat to match it best. Use a suitable color and a small brush. Detect the leakage in the water cooler. Most trickles result from inner cracks. In some conditions, the crack may penetrate through to the cooler’s external shell.
  2. Grit the edges of the crack and the space around it with 120-grit sandpaper. This will increase the strength of epoxy adhesion.
  3. Now scrub with a bead of plastic epoxy resin to the crack, stuffing it in with a small epoxy spreading instrument. If the crack pierces to the outside of the water cooler, pack this crack with epoxy also.
  4. Spread leftover epoxy over the region surrounding the crack, so that a patch is formed. This helps to bind the edges and forms a strengthening barrier. 

4. Leaking Tray

Another possible reason that could cause leaking is a drip tray that is placed beneath taps and is filled with water and causing water outflows.


Remove the tray and wash it with clean water and soap to avoid this issue, checkout dripping tray on a daily basis because standing and overflowing water constantly spreads not only irritating odor due to the growth of bacteria but also causes rusting.

5. Smelly Water

In our daily life, the main purpose of a water dispenser is to keep water cold to quench our thirst. Sometimes water can be smelly and unclean. The possible reason behind it is the production of bacteria in the water cooler because dampness and hotness are ideal conditions for the growth of bacteria. No need to worry about it; there is a simple solution to this issue. Simply follow some instructions.


    • Always wash your hands before getting in touch with the water cooler. This is necessary to avoid the transfer of bacteria from your hand into the cooler.
    • Wash the drip tray daily.
    • Try not to pour coffee or tea into the dripping tray
    • Wash out the 5-gallon water frequently

6. Water Temperature Is Not Precise

If your water cooler is not warming or cooling water, you may have forgotten to turn on the heating or cooling button.

If it was not on, simply turn it on and wait for some minutes to check whether the issue is resolved or another issue causing the problem.

7. Problem In Dispensing Hot Water

You have to keep in mind that the water dispensers are designed to chill the water and the hot water option is added in your machine as a bonus. The cold water tank has more use as compared to hot water.

The hot water tap is used only to make a cup of tea or coffee. Probably warm water is not consumed by someone at all. And more water takes 5 minutes to refill and another five minutes to heat up the water.

Look on the backside of the water dispenser where you would find two buttons one for the cold usually green in color and the other one is red that is for hot water. Make sure the switch button for the hot water is turned on. Now check again whether the hot water is coming.

8. Water Dispenser Not Giving Chilled Water

Those who are familiar with the use of electric appliances understand that there is also a limited capacity of any electric device. There might be a chance in summer due to the intense heat, the water dispenser capacity of chilling water slows down. It is normal in summer so there is no need to worry about it.

9. Water Cooler Not Dispensing Any Water

One should make sure the bottle is not unfilled and that there is sufficient water in the 5-gallon water bottle.


Take away the water bottle from the water dispenser and place it back on the water cooler though at the same time keep both taps open. Do not try to do this without help. You need one person to hold the taps and another to do away with and re-attach the bottle.
