Check the cooler is plugged in, the red power switch is on, the power cord is secure and the mains outlet is working.

• Make sure your cooler is plugged in and switched on (you’d be amazed at how often this is the cause) – see question "No power?". • Are lots of people using the cooler? If the tank has been drained, wait 15 minutes for the water to chill. • Check that your cooler’s thermostat is set to an optimum temperature for cooling the water (found at the back of the cooler). To make the water colder, rotate the screw in the clockwise direction approximately 1 hour position. Allow the cooler to stabilize for 2-3 hours to ensure proper temperature of the cold water. (Note: do not change the setting by more than 1 hour setting at a time to prevent freezing).
