Please check if the dispenser has an abnormal prompt.

The dispensed water is not cold enough.

| Please check if the dispenser is in night mode, as the compressor does not perform refrigeration in this mode.
Please check if a large amount of cold water has been dispensed continuously. If yes, the dispenser may be undergoing the refrigeration process.

The actual temperature does not reach the set temperature.

| The heating part needs to be preheated, and the set temperature cannot be reached immediately within the first few seconds.
The hot water will lose part of the heat from the water outlet to the container .
The container is too low at temperature, thereby absorbing part of heat.
Raw water temperature is too low.
There is a deviation between the actual water output and the set water output?| ****

There will be deviation in components such as pumps in the dispenser, and the deviation of -1 0% to 10% is normal.

There are white bubbles in the water .

| ****

It is normal. After the water flows to the heating element and there is contact, part of it will be vaporized to generate bubbles. These bubbles float on the surface of the water until they are dissolved.
