Why does the Xiaomi Smart Filtered Water Dispenser Pro dispense hot water that is cool for the first few seconds and takes a few seconds to reach the set temperature?

A: When using the Xiaomi Smart Filtered Water Dispenser Pro for the first time, room-temperature water flows for 3 seconds before activating the heating process due to the absence of water in the hoses.
During regular use, as water is already present in the hoses, the initial water temperature may be lower as the instantaneous heating process requires some time.
A limited hot water supply can accentuate the initial low temperature in both scenarios mentioned above.
Tips:
Please discard the first cup of water before use to minimize temperature deviation.
