Xiaomi water dispensers (including Viomi and Mijia sub-brands) are becoming increasingly popular due to the combination of smart features and affordable price. However, many users face difficulties when first switching on: the device does not respond to buttons, does not connect to the application or emits errors. In this article, we will analyze the step-by-step launch algorithm for all current models (2020-2026), and also explain how to avoid typical errors.

It is important to understand that the inclusion process depends on the type of dispenser: desktop (for example, Viomi Water Dispenser). V1), Floor (Mijia Smart Water Dispenser) and smart with heating/cooling (Viomi) V3 Pro! We'll cover all options, including touch-controlled models and mechanical buttons. If your dispenser doesn't respond to action, check the troubleshooting section.

Preparation of the dispenser for the first inclusion

Before you connect your device to the network, follow a few mandatory steps, which neglect can lead to malfunctions or even breakdown.

First, unpack the dispenser and check the equipment.

• 📦 The dispenser itself with the lid
• ⚡ Power cable (for models with electric heating)
• 📄 Instructions in Chinese/English (Russian version is rare)
• 🔧 Fixed elements (if the model is wall-mounted)
• 💧 Filter (for models with water purification, for example, Viomi) V3)

Pay special attention to washing the system, even new dispensers can contain industrial dust or preservative lubricant inside.

1. Pour 2-3 liters of pure water into the tank (without a filter!).
2. Turn the dispenser on and wait for the system to fill up (usually takes 1-2 minutes).
3. Pour the water through the tap, repeat the procedure 2-3 times.

💡

If your model is equipped with a carbon filter (for example, Viomi). V3 Pro, first run without a filter – so you wash the remains of coal dust from the system.

For the Mijia Smart Water Dispenser, allow the device to stand in a room for 2-3 hours before first switching on, to stabilize the pressure in the cooling system.

Important: compressor-cooled models (such as the Mijia Smart Water Dispenser) can make loud noises when first turned on, which is normal. The compressor calibrates within 5-10 minutes.

3. Customization via the Mi Home app (for smart models)

If your dispenser supports Mi Home connectivity (e.g. Viomi) V3 Mijia Smart Water Dispenser 2, you can't do without the app:

• ⏱️ Water supply timer.
• 📊 Consumption statistics.
• 🔋 Water level in the tank.

If the device is not in Mi Home, check:

• 📶 Is the phone connected to 2.4 GHz Wi-Fi (smart dispensers do not work with 5 GHz!).
• 📍 Is the dispenser in the range of the router (maximum 10 meters without obstacles).

❄️ Cooling mode

It is activated similarly to heating, but using a Cold button or snowflake icon (❄️). Cooling works to 5-10°C. Pay attention:

• 🕒 The first cooling takes up to 30 minutes.
• 🔋 In cooling mode, the dispenser consumes more electricity.

If the dispenser is making a continuous squeak, it's usually a critical error.

• 🔴 1 Short Signal – Low Water Level.
• 🟡 2 signals - error of the temperature sensor.
• 🔴🔴 3 signals - failure of the heating element.
• 🟡🟡🔴 1 long + 1 Short – Error of Wi-Fi connection.

💡

If the dispenser beeps and does not respond to the buttons, try resetting to the factory settings: disconnect from the network, press the Power button and connect back, holding it for 10 seconds.

For models with display (Viomi) V3 Pro) error codes are displayed on the screen, for example:

Heated/cooled dispensers consume 300-800 watts per hour to reduce consumption:

• 🕒 Turn off cooling overnight (unless you use cold water).
• 🔌 Use a timer socket to automatically shut down.
• ☀️ Install the dispenser away from direct sunlight (overheating increases the load on the compressor).

💡

For models with display (Viomi) V3 Pro) activate Eco mode in the settings. It automatically turns off the heating if the water has not been used for more than 2 hours.
