Coolers, which chill and dispense drinking water, can be found in nearly any locker room, hospital lobby or office break room. While cooler tanks can be installed within a wall to provide a source of cold water for a drinking fountain, bottled water coolers are more convenient and thus are more common in the household. If your water has become warm or you notice a leak, it may be time for a troubleshooting session.

Enjoy cool, crisp water after troubleshooting your cooler.

Step 1

Check that the unit is firmly plugged into an electrical wall outlet. Also ensure that the opposite end of the power cord is connected to the back of the cooling unit. If the cord has begun to fray or keeps slipping out of the cooling unit's housing, contact the manufacturer.

Step 2

Inspect the installed bottle if you notice a leak. In most cases, the leak results from the bottle and not from the cooling unit itself. Look for hairline cracks, which are typically thin, jagged and long.

Step 3

Lift the bottle up and out from the cooling unit, using caution not to spill or drop the bottle. Uncap a new bottle and place it into the cooling unit. If the leak stops, the problem was the old bottle.

Step 4

Remove the drip tray from below the dispensing taps and empty it into your sink if you notice another leak. The tray can fill up and begin to overflow if left untended for several days.

Step 5

Tighten the dispensing taps by twisting them counterclockwise with your hands if you notice that they are leaking. Avoid tightening them with a wrench, as this may crack the plastic or strip the threading. If this does not fix the leak, a technician should be called in to replace the taps.

Step 6

Correct the flow of water by lifting the bottle out of the cooling unit. Have an assistant hold both taps open as you reinsert the bottle.
