Why does the error indicator turn on and the App shows a low-temperature alarm on the Mijia Smart Water Purifier N800G?
The Mijia Smart Water Purifier N800G is designed to operate safely within a water temperature range of 5–38 °C. If the inlet water temperature falls below 5 °C, the purifier triggers a low-temperature (anti-freeze) alarm, displayed on both the purifier indicator and the Xiaomi Home App. This alarm prevents potential damage to internal components, such as filters or pipes, caused by freezing.
When this occurs, immediately turn off the water supply and unplug the purifier to reduce the risk of leaks or other hazards. Once the inlet water temperature rises above 5 °C, restart the purifier to resume normal operation.
Following these steps ensures safe operation and extends the purifier's lifespan of the Mijia Smart Water Purifier N800G while maintaining reliable purification performance. The low-temperature alarm is a normal protective feature and does not indicate a malfunction of the device.
