• 🧼 Consistency: Optimal viscosity, like a regular liquid hand soap (not gel or too thick.
• 🔬 Chemical Composition: Avoid soaps with abrasive particles, bleach or aggressive surfactants (for example, SLS high-concentration).
• 📏 The volume of packaging: Xiaomi dispensers are designed for capacity up to 300-500 ml. Large bottles will have to be transfused.

Before you pour a new soap, the device must be properly prepared, and neglecting this step is the main cause of failure of pumps and sensors.

Disconnect the device from the outlet (if it is powered by the network)|

Remove batteries (for battery-powered models)|

Wash the tank with warm water (without detergents!)|

Dry all the details with a paper towel.|

Check the silicone seals for wear-->

Pay special attention to washing the tank, and if there's traces of old soap in it, they can react with a new soap, which will lead to precipitation.

To remove persistent deposits (for example, from soap with oils), use a solution of vinegar (1 part vinegar to 3 parts water).

Step-by-step instructions for replacing soap

The process of filling the dispenser depends on the model, and below is a universal instruction that is suitable for most Xiaomi devices, including the Mi Automatic Soap Dispenser and the Mijia Smart Soap Dispenser Pro.

1. Opening of the tank

In most models, the soap tank is located at the top of the device, so you can open it.

• 🔄 Press the cover and turn it counterclockwise (for models with threaded mounting).
• 🔳 On latch models (such as the Mijia Mini), press the button on the side and pull the lid up.

2.Pouring soap

So the important thing to do here is to avoid two errors: overflow and bubble formation.

1. Pour the soap into the tank before the mark MAX (It's usually 300-400 ml).
2. Hold the soap bottle at an angle of 45°, to minimize foaming.
3. If the soap is thick, dilute it with distilled water (no more than 10% of the volume).
4. Close the lid and turn it clockwise before you click.

3. System upgrade

After replacing the soap, the dispenser may give an error E01 (or to work in jerks to avoid it:

• 💧 Press the touch button 3-5 times to pump soap through the system.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when replacing soaps that lead to breakdowns. TOP-5 problems and solutions:

• 🚫 Soap overflow: If you pour more mark MAX, When you heat up (like in the bathroom), soap can leak out through seals. Solution: always leave 5-10mm of free space.
• 🧴 Using a shower gel: The thick texture of the gels clogs the pump.Solution: dilute the gel with distilled water in a 1:1 ratio.
• 💦 Water entering the electronic unit: When the tank is washed, water can flow into the bottom of the device. Solution: Dry the dispenser in an upside down form for at least 2 hours.
• 🔋 Forgot to take out batteries: If you replace soap with batteries installed, accidentally pressing can cause the pump to turn on without soap, which will put it out of order.Solution: always remove the power cells before maintenance.

How to prolong the life of Xiaomi dispenser

The life of an automatic dispenser depends not only on the quality of the assembly, but also on the correct maintenance. Here are 5 rules to help avoid breakdowns:

• 🔄 Routine flushing: Wash the tank and spout with warm water every 2-3 months, even if the soap is not finished.
• 📱 Firmware Update: In the Mi Home app, check for updates – they often fix sensor errors.
• 🔋 Battery replacement: Use only alkaline batteries (Duracell, Energizer) cheap cells can leak and damage the board.
• 🌡️ Temperature: Do not place the dispenser near heat sources (e.g., above the washing machine) and the optimum temperature is 10-35.°C.
• 🛠️ Preventive check: Check the silicone seals every six months. If they're not elastic, replace them.

For models with a UV lamp (e.g. Mijia) UV Sterilization is important:

• 💡 Change the lamp every 6-12 months (depending on the intensity of use).
• 👁️ Do not look at a working lamp - UV radiation is harmful to vision.
