Xiaomi’s automatic soap dispensers have become an integral part of the modern bathroom, combining aesthetics, hygiene and usability. Many users, when purchasing a device for the first time, face difficulties in first refueling, as the mechanism requires some preparation to work properly. If you just pour liquid into the tank, the pump may not earn or produce too little foam.
In this article, we will discuss in detail the process of refueling various models of smart dispensers, including popular versions of Mijia Auto Induction and Mijia Foaming Hand Wash. You will learn about the nuances of choosing detergent, the right sequence of actions and methods of cleaning the system in the event of a clogging. Compliance with refueling technology will prolong the life of the device and ensure stable foaming.
The main difficulty is to remove air from the fluid intake tube, since the air plug prevents the supply of soap to the nozzle. It is also important to consider the viscosity of the product used, since too thick a gel can overload the motor, and excessively liquid - will not give a stable foam. The correct approach to the maintenance of the gadget ensures its smooth operation for many months.
Preparation of the device and selection of consumables
Before starting the procedure, you need to make sure that you use compatible components. Although Xiaomi dispensers are designed with the original interchangeable units, many users prefer to refuel them themselves to save budget, in which case it is critical to choose a liquid with the right consistency so as not to damage the pump mechanism.
The best choice is liquid soaps with a viscosity close to water or a light shower gel. Too thick creamy products can create excessive pressure in the system, which will lead to a rapid discharge of batteries or engine failure. If you use a concentrate, you must dilute it with water in the proportion specified by the manufacturer, usually one to three or one to four.
Also worth paying attention to the chemical composition of the product: aggressive alkalis or acids can damage the seals and plastic parts of the tank. It is best to choose neutral hypoallergenic compounds that do not leave sticky plaque on the walls of the bulb, which will simplify the subsequent cleaning and prevent clogging of the outlet.
⚠️ Warning: Never use soap with solid abrasive particles, scrubbing elements or large floral petals. Such additives are guaranteed to clog the thin tube of fluid intake and disable the pump.
Step-by-step instructions for filling the dispenser
The refueling process begins with the removal of the top of the device, which requires holding the tank with one hand and gently pulling the top electronics unit upwards with the other, and don't put too much effort into it, because the connection is held on friction latches and rubber seals, which are easily damaged when jerked.
Once the block is removed, you'll see an inner tube going deep into the bulb, and if there was residue of old soap in the tank, it should be thoroughly washed away with warm water to avoid mixing different chemicals, and a mixture of different components can lead to precipitation that will clog the system.
☑️ The algorithm for refueling the dispenser
Pour the prepared soap into the tank without exceeding the maximum mark MAX. Overflow can cause the upper part of the liquid to be squeezed out and get to electronic contacts, which is unacceptable. Once filled, carefully set the unit with the motor in place until the characteristic click or tight fit.
The most important step is to pump the system, because there's air inside the tube, you have to force the feed mechanism to start, so you can put the device over the sink and press the touch button five times in a row, and you have to see how the air and soap mix starts to come out of the nose, and then the uniform foam will flow.
Features of working with foam-forming models
Foaming models work by saturating the liquid with air before discharge. Inside the top unit is a special filter mesh that whips the flow into the air foam. When filling these devices, the quality of the foam directly depends on the degree of filling of the reservoir and the state of the filter element.
If the foam is too liquid or settles quickly, the concentration of soap may be too low. In such cases, it is recommended to add a little more active substance or use special concentrates for foaming agents. Conversely, if the device makes a buzzing sound, but the foam does not go, the filter may be contaminated with dried residues.
In cold rooms, the viscosity of the liquid increases, and it is more difficult for the motor to pump it through a fine mesh, so it is recommended to place such dispensers in warm bathrooms, away from drafts.
Compatibility table and troubleshooting
Even with all the instructions, there can be situations where the device is not working properly. Below is a table that will help diagnose the most common problems and find a solution.
| Symptoms. | Probable cause | Decision-making |
|---|---|---|
| LED flashes yellow | Low battery charge | Replace 4 AAA batteries with new ones |
| No soap, engine buzzing | Clogged tube or high viscosity | Dilute the soap with water, clear the tube |
| The foam is too liquid | Little soap or a lot of air | Remove the soap, pump the system 5-10 times |
| Sensor's not responding to arm | Sensor contamination or discharge | Wipe the front panel, check the batteries |
Special attention should be paid to the power of the device. Using cheap batteries with low recoil current can lead to the fact that the motor does not have enough power to create the desired pressure, as a result, the dispenser will operate unstable even if the charge indicator shows normal.
Cleaning and maintenance of the feeding mechanism
Regular maintenance is key to a long life for your gadget, and over time, soap residues can accumulate on the walls of the tube and inside the pump, which dry out and crystallize, especially if the device has been idle for several weeks.
For preventive flushing, remove the top and put the tube in a container of warm water. Run the feed mechanism several times so that the water goes through the system and washes away the residues of old soap. You can add some citric acid to the water to dissolve the mineral deposits.
- 🧼 Rub the touch panel with a soft wet cloth, do not use abrasive sponges.
- 💧 Once a month, carry out a full wash of the system with warm water.
- 🔋 Remove batteries if you do not plan to use the dispenser for a long time.
If you notice that the jet has become curved or splashed to the sides, check the outlet. There may have been a dried lump of soap. Carefully remove it with a cotton swab dipped in alcohol or water. Do not use sharp objects so as not to damage the geometry of the nozzle.
