Xiaomi’s automatic foam dispensers have become an integral part of the modern interior, providing hygiene and usability. However, owners often face a lack of understanding of how to properly maintain the device so that it works for years without failure. Refueling errors can lead to failure of the mechanism or poor foaming.
In this article, we will take a closer look at the process of replenishing liquid soap, look at the proportions required for the perfect foam, and answer questions about sensor maintenance, explain why regular soap may not work and how to avoid drying out the residues in the nose.
Proper operation of the automatic dispenser extends the life of the battery and the pump. We will discuss the technical details of the design so that you can confidently manage your bathroom gadget.
Preparation for refueling and selection of consumables
Before you start the process, you need to prepare your workplace and make sure you have the right handwashing appliance. Not all fluids are compatible with the Mijia pump system. Too thick gels or products with large abrasive particles can damage the internal mechanism.
The ideal solution is to use a low-viscosity liquid soap, and if you plan to use a concentrate, you have to dilute it with water, and the proportions are usually specified by the soap manufacturer, but the ratio is the standard for foam dispensers. 1 clap-to 3-4 water-spoon.
- 💧 Low viscosity liquid soap or special refill set.
- 🚰 Pure water (better filtered or distilled) for dilution.
- 🧻 Dry napkin or towel for cleaning the body.
- 🔋 Checking the battery charge (alkaline is recommended). AA).
It's important to understand that the concentration of the solution directly affects the density of the foam. If the foam is too liquid, add a little more soap. If the device is buzzing but not foaming, it may be too thick.
Step-by-step instructions for filling the dispenser
The process of refueling Xiaomi Mijia Automatic Foam Soap Dispenser is as simplified as possible by engineers, but requires compliance with a certain sequence of actions. First, take the device in your hands and make sure that it is turned off or in a safe position to fail the sensor accidentally.
Rotate the top cover with a counterclockwise mechanism carefully. It doesn't usually take too much effort, but if the block is jammed, check if it's stuck because of the dried soap. After unscrewing, remove the entire mechanical unit from the glass bulb.
☑️ The gas station algorithm
Now you can pour the prepared mixture directly into a glass bulb or into a special compartment if the model allows it. Don't overflow the container - leave about 1-2 centimeters to the neck free. This is necessary to create the correct air pressure when the pump is running.
⚠️ Warning: Never immerse the top mechanical part with electronics and motor in water or detergent entirely.
Once the container is filled, insert the mechanical unit back into the glass bulb. Tightly twist the lid clockwise to the point, make sure the fluid intake tube is lowered to the bottom and not curved.
Foam density setting and calibration
Many Xiaomi dispensers have a foam control, which can be mechanical (a slider on the body) or software (configure via the Mi Home app). If you use a mechanical regulator, moving the slider changes the duration of the engine.
To calibrate the foam density, experimentally squeeze a few portions into the sink. If the foam settles too quickly, increase the concentration of soap. If the device gives out water instead of foam, check if the aerator clogs at the exit.
| Parameter | Low density. | Optimal foaming | High density |
|---|---|---|---|
| Proportion (Soap:Water) | 1: 5 | 1: 3 | 1: 2 |
| Consistency | Liquid, watery | creamy | Thick, heavy. |
| Battery consumption | Minimum | Medium. | High-pitched |
| Risk of blockage | Low. | Low. | Medium. |
Using the Mi Home app allows you to more accurately adjust the sensitivity of the sensor and the volume of foam issued, which is especially convenient if the dispenser is used by children who need a smaller portion.
The Secret to Perfect Foam
Clearance of blockages and nosedive maintenance
The most common problem in use is the drying of soap in the outlet, which happens if the dispenser has not been used for a long time or if the drops remain on the nose after use, and the device hums, but the foam does not come out.
To clean, remove the top block and wipe the outlet with a wet wipe. If the clog is deeper, you can drip some warm water right into the hole and let the mechanism work idle (without a flask) to push the cork.
- 🧼 Wash your nose with a dry wipe after each filling.
- 🌡️ Use warm water to dissolve frozen residues.
- 🔄 Regularly (once in) 2-3 month) wash the system with clean water.
If you notice that the jet is going sideways, not vertically down, check if the filter net inside the nose has shifted. Carefully correct it with a thin object, such as a toothpick, without damaging the cell.
⚠️ Warning: Do not use sharp metal objects (needles, pins) to clean the aerator mesh. Damage to the mesh will cause the device to give out liquid rather than foam.
Features of operation in winter
In winter or in low-temperature areas, the viscosity of liquid soap may increase, which puts additional stress on the motor and reduces the quality of foaming, in which case it is recommended to use warmer water for dilution or move the dispenser to a warmer place.
Also, you should consider that alkaline batteries in the cold or in the cold discharge faster. If the dispenser began to work unstable in the winter, first replace the batteries, even if the indicator is still on.
Do not leave the device in direct sunlight, as ultraviolet light can change the properties of the plastic and lead to deformation of sealing rubber bands, which will cause leaks.
💡
Store spare batteries at room temperature, and cold batteries that have just been brought in from the street may temporarily lose some of their capacity.
Frequent errors and troubleshooting
Users often make mistakes that cause the device to fail prematurely, and one of the biggest mistakes is ignoring the low-charge indicator, and running the motor at low voltage can cause it to overheat and break.
Another mistake is the use of aggressive chemicals, such as chlorine solutions or alcohols in high concentrations, which can eat up plastic tubes and seals inside the mechanism.
If the light flashes red immediately after the new batteries are installed, they may be incorrectly installed or the contacts have become oxidized. Wipe the contacts with a cotton swab dipped in alcohol and make sure the polarity is correct.
💡
The stable operation of the dispenser depends on the quality of the batteries used and the correct proportions of the mixture of soap and water.
