Power Issues

First, make sure that you have the correct power source for your water cooler. Check the manual to find out what kind of power the machine requires. If you aren’t sure, you can always call a repair technician to help you figure out what the issue might be. 

A power outage can cause your water cooler to malfunction, so it’s best to keep the unit plugged in at all times. This can prevent any damage to the unit from occurring and will ensure that it’s able to function correctly as needed. 

If you’re not sure if your water cooler is plugged into the wall or not, you can use a multimeter to test the system to see if it’s receiving the right amount of voltage and power. If it’s not, then the problem may be with the water cooler itself. 

Another potential problem is a clogged condenser, which can cause the system to run unnecessarily and overheat. If you suspect that your condenser is clogged, you can remove the cooler from the wall to check it out. 

The condenser is located on the top right side of your cooler. It’s important to check it out to ensure that it’s free of debris. 

If your condenser is clean, you should be able to turn the unit on and it should be able to work properly. If it’s not, you might need to replace the component. 


If you’ve noticed that your cooler is leaking, it’s important to get the leak fixed as soon as possible. This can be caused by a variety of different things, so it’s important to take care of the issue before it gets worse and causes major damage. 

In most cases, these problems can be easily fixed by a professional. They’ll be able to fix the leak and make sure that your cooler is working as needed. 

Drip Tray Overflows

If the drip tray on your cooler is overflowing, you might want to try adjusting the thermostat to see if that helps. The thermostat should be located somewhere on your water cooler, so look for it when you’re checking it out. 

The next step is to empty the drip tray and clean it. Using a small brush, gently scrub the inside of your cooler to remove any dirt and grime that has been collected there. 

It’s also a good idea to empty the water reservoir as well since it can become overfilled with grime and debris if not cleaned regularly. 

A clogged condenser can affect the temperature setting on your water cooler, so it’s important to clean the condenser as soon as you notice any signs of dirt and grime. 

The next step is to wash the interior and exterior of your cooler with hot, soapy water. Ensure that the spigots are thoroughly cleaned as well, as these are the most contact parts of your cooler. Once your water cooler is clean, you can refill the water reservoir with boiling water. This will disinfect the entire system and ensure that your cooler is functioning properly again.
