How to fill up the Xiaomi dispenser: full instructions

Xiaomi’s automatic dispensers have become a popular element of bathrooms due to their convenience and hygiene, but owners often face a misunderstanding of how the device works when they first try to replenish their supply. Many users mistakenly believe that you can pour any thick soap into the tank, which leads to rapid pump failure or clogged valves. In this article, we will discuss in detail how to properly fill the dispenser so that it lasts for many years without failure.

The main challenge is the pump design, which is designed to have a specific viscosity of the liquid. If you just bought a Mijia or Smart Soap Dispenser, you need to get familiar with the requirements for consumables. Ignoring these rules often leads to the device stops feeding foam or starts spitting liquid.

We have prepared a detailed guide to help you avoid common mistakes and understand the physical principles of the automatic dispenser. Proper preparation of the mixture and adherence to the sequence of actions ensure stable operation of the sensor and motor.

Preparation of necessary materials and tools

Before you start the process, make sure you have all the ingredients you need to refuel successfully. You will need not only the liquid filler itself, but also clean water, preferably distilled or filtered, to avoid scaling on the mechanism. Using high-hardness tap water can reduce the efficiency of the micro pump over time.

It is also important to prepare a mixing tank if you plan to dilute the concentrate, although many modern models allow you to do this right in the tank. Make sure your hands are clean and the work surface is dry to prevent foreign particles from entering the tank. Any dust or villi can cause a narrow supply channel to block.

⚠️ Warning: Never use abrasive cleaning products or hot water (above 40)°C) for washing the inside of the tank, as this may deform the plastic and impair the leakiness of the valve.

Pay special attention to the choice of the soap solution, there are many options on the market, but not all of them are suitable for automatic systems. Too thick gels can make the motor work with overload, which will lead to rapid battery discharge or failure of electronics.

Selection of the appropriate liquid for the dispenser

The key to using the device is to understand the difference between a regular liquid soap and a special foam concentrate. Xiaomi dispensers, depending on the model, can be designed either for finished foam or to create foam inside the case. Most models, such as the Mijia Automatic Induction Soap Dispenser, require a foam solution of low viscosity.

If you use a regular thick soap, it must be diluted with water in the proportion specified by the manufacturer, usually a ratio of 1 to 5 or 1 to 7. There are special concentrates for auto-dispensers that already have the desired consistency and do not require additional mixing, which greatly simplifies maintenance. Using the wrong liquid is the main reason why the device stops working correctly.

When choosing a tool, pay attention to the absence of large particles, scrubbing elements or oils that can solidify and clog the spray nozzle. Chemical composition is also important: aggressive alkalis can damage the sealing rings and plastic parts of the pump.

For best results, it is recommended to purchase original replacement units or certified analogs, designed specifically for the Xiaomi Smart Home ecosystem.This ensures that the viscosity of the liquid will be within the permissible limits for a particular pump model.

Step-by-step instructions for refueling the device

The refueling process begins with gently unscrewing the top of the device, where the pumping mechanism and the sensor are located. Carefully not to damage the thread or drop the electronic part into the water. Once the lid is removed, you will see a tank that usually has minimum and maximum filling levels.

If you're using a concentrate, you should first pour the water you need into the tank, then add the soap solution. If you're using the finished mixture, just fill the container to the MAX mark. It's important not to transfuse the liquid above the maximum mark, because when you twist the lid, the displaced air can create excess pressure and squeeze some of the contents out.

Once the container is filled, tightly twist the top of the device. Make sure the connection is sealed, but don't put too much effort into not breaking the thread. Now the device is ready for its first start or to continue working.

Some models require the activation of the pumping mode if there is air left in the tubes, usually by pressing the sensor several times or using the reset button if it is provided by the design, the initial start can take several seconds until the pump creates the necessary pressure in the system.

Sensitivity and operating mode setting

Many modern Xiaomi models allow you to adjust the volume of foam output and the sensitivity of the infrared sensor. These settings are often available through the Mijia app or by a combination of clicks on the control button. Adjusting the sensitivity of the sensor is especially important if the dispenser is installed in a niche or near other reflective surfaces.

Changing the mode of operation often involves pressing a button or a series of short presses, for example, five quick presses can switch the device to continuous feed mode and three can change the portion size. Details about specific combinations for your model can be found in the manual or in the application.

Using the Mijia app provides additional features such as battery power tracking and usage statistics, and if your model supports remote control, be sure to connect it to the network to access the advanced functionality.

💡

If the dispenser is in a dark corner, the sensor sensitivity can be increased through the app so that it responds to the movement of the hand at a greater distance.

Solving common problems when refueling

One of the most common problems is when the device is buzzing, but the foam is not coming out. This usually indicates suffocation of the system or clogging of the outlet. In the first case, you need to activate the sensor several times, holding the dispenser above the sink, so that the pump pump pumps air and starts to supply liquid.

If the soap is being jerked or splashed, check the nozzle hole for clogs. Dried soap residues can block the exit, in which case a careful clean with a thin needle or washing with warm water will help. Remember that after washing, the device must dry completely before reassembling.

⚠️ Warning: If the device makes a strange sound or is interrupted after refilling the new soap, immediately stop using and flush the system.

Another problem can be the rapid discharge of batteries, which often happens if you use too thick a solution that requires more power from the electric motor to pump, in which case it is recommended to increase the proportion of water in the mixture or replace the batteries with better analogues.

Care and maintenance of the automatic dispenser

For long-term service of the device, it is recommended to carry out preventive cleaning of the tank and the pump group every 2-3 months. Even with the use of high-quality solutions, plaque can form over time on the walls, which worsens the operation of the sensor mechanism.

Also, keep an eye on the contacts in the battery compartment. Oxidation of the contacts can cause unstable electronics, periodically wipe them with dry cloth and check the density of the batteries, using good batteries prolongs the life of the batteries themselves, but also protects the device from leaks.

Store spare canisters with soap in a cool place, protected from direct sunlight to preserve the properties of the liquid. Incorrect storage of consumables can lead to their dissection or change in viscosity, which will affect the quality of the dispenser.

💡

Regularly flushing the tank with warm water every 2 months prevents 90% of clogging problems and ensures the pump is running smoothly.
