How to change soap in the Xiaomi dispenser: a detailed guide

Xiaomi’s automatic dispensers have become an integral part of the modern bathroom, providing hygiene and ease of use. However, many owners face difficulties when first trying to refill or switching to another detergent. Incorrect fluid replacement often leads to clogs, device failure to work or damage to the foam supply mechanism.

In this article, we will discuss the process of soap replacement, the compatibility of different types of liquids, and provide recommendations for the maintenance of a smart dispenser. Compliance with refueling technology will extend the life of the gadget and avoid the need for expensive repairs or purchase a new device to replace a spoiled one.

Before you start, it's important to understand that the design of the dispenser, whether it's the Indogoo model or the original Xiaomi Mijia, requires careful handling of the pump system. Unlike conventional pump bottles, it uses electronics and a motor that is sensitive to the viscosity of the medium, so a simple eye replacement won't work here, you need consistency.

Preparation for the replacement of liquid soap

The first step is always to prepare the workplace and the device itself. You'll need a clean surface, paper towels to remove possible droplets and, of course, the detergent itself. It's critical that the container is clean if you change the type of soap, as residues from old chemistry can react with new ones.

If you use a concentrate, you have to dilute it in the right proportions beforehand with water. For automatic dispensers, viscosity is crucial: too thick will put excessive pressure on the motor, and too liquid will flow out of the water. The ideal consistency is like liquid kefir or light cream.

💡

Use only warm water to breed concentrates, as in cold water, soap shavings or gel can dissolve unevenly, forming lumps that clog the tube.

It's also worth checking battery power or battery availability. A weak charge can cause the motor to not turn the mechanism through and you get an incomplete portion of foam or air instead of soap. Make sure the contacts in the power compartment are dry and clean before you start work.

Step-by-step instructions for filling the dispenser

The soap replacement process in Xiaomi’s dispenser looks the same for most Mijia series models. First, you need to unscrew the top of the device from the tank. Do this confidently, but without undue effort, so as not to break the thread on the plastic case.

Once you remove the top, inspect the fluid intake tube, which often has a mesh filter at its end that could have clogged with dried residues of old soap, wash the tube under the water stream, gently clean the filter with a soft brush if the plaque is visible, a critical step for stable operation.

Put the prepared soap into the tank. Pay attention to the MAX markings, you can't pour above this mark, because when you twist the lid, the displaced air will create excess pressure, and the soap can be squeezed out through the valves. Curl the top back up to the characteristic click or stop.

Choosing the Right Cleaner

One of the most common questions users ask is what to put into the dispenser. Manufacturers often recommend using original replacement units, but the market offers many alternatives. The main rule is that the product should be liquid and contain no large abrasive particles.

Conventional liquid hand soaps, shower gels and even diluted washing gels are well suited, but avoid high-concentration oils or creamy textures with a density greater than 1.2 g/cm3. These substances can quickly thicken inside the pump's narrow channels after drying.

For families with children or people with sensitive skin, hypoallergenic baby products are an excellent choice, they tend to have optimal viscosity and do not contain aggressive components that could damage rubber seals inside the pump system.

Note that alcohol antiseptics can overdry rubber pads over long-term use, and if your goal is hand sanitizers, it is better to alternate alcohol with regular soap or use devices specifically designed for sanitizers.

Adjustment of foam supply volume

When you change the soap, you often need to adjust the amount of portions you give out, and in Xiaomi models that support the Mijia app, you can do this through a smartphone, but there is also a mechanical way of setting up that works without a network connection.

To change the feed volume, you usually use a combination of buttons or a long press on the touchpad. For example, triple pressing can switch modes between economy, standard and amplified. The exact sequence of actions depends on the particular model, so check the instructions for your device.

💡

Properly configured supply volume saves up to 30% of consumables per month, while maintaining the effectiveness of hand washing.

If the dispenser starts to emit air instead of foam immediately after filling, don't panic. This is normal, because the tube may have left air. Make a few blank starts (pressing a button without touching hands or holding your hand) until a stable stream of soap foam goes.

Problems and services

You may experience a situation where the indicator is on, but the soap is not served, most often it indicates a clogged outlet or air entering the system, and regular prevention will help to avoid such situations.

⚠️ Warning: Never attempt to clean the outlet with sharp metal objects such as needles or pins.This can damage the delicate valve mechanism and the leakage will be irrevocably damaged.

To clean, use warm water. Remove the top, put the tube in a glass of warm water and press a few taps. This will rinse the internal channels and remove stagnant clots. If the problem persists, check if the battery is dead, even if the indicators are burning - under load voltage can drop critically.

Also keep the sensor clean. Dust or sprays of soap on the sensor window can lead to false positives or, conversely, to ignore the hands.
