Error phenomenon
Possible reason & Solution
Displayed temperature after sterilization
Deviation from set temperature
● Sterilization is completed after a period of time, the current display temperature and the user set
temperature is not consistent with the normal phenomenon. It takes a long time for the water tank
temperature to decrease from 70
ć
to the user setting temperature;
● Turn on the forced sterilization or automatic sterilization, the set temperature of the unit becomes 70
ć
(once
effective). The sterilization symbol of the heating process lights up. After the water tank temperature
reaches 70
ć
to complete the sterilization, the sterilization icon goes out.
Deviation of display from set temperature.
When the unit reaches the temperature and stops, there may be a small deviation between the display
temperature and the set temperature, which is a normal phenomenon.
The unit heats up for a period of time and
shows that the temperature has not risen.
● If the user continues to use hot water, resulting in the lower part of the tank into the more cold water, the
unit mainly heats the lower part of the water temperature, the priority of the temperature under the tank
rises while the upper part of the tank does not rise significantly is a normal phenomenon.
● Check whether the host is working properly and the tank setting operation mode, the tank energy-saving
mode host heating hot water to the maximum water temperature will stop working, using electric heating
heating, check whether the electric heating is working properly.
