How to open the dispenser of liquid soap Xiaomi Mijia: instructions with photos and tips

Xiaomi Mijia liquid soap dispenser has become a popular smart home gadget thanks to its minimalist design, automated soap supply and integration with the Mi Home ecosystem. However, many users face difficulties when first refueling or cleaning the device - the manufacturer does not always describe the process of opening the case in detail. In this article, we will analyze all official and alternative ways to disassemble the dispenser, as well as provide maintenance recommendations to make the device last longer.

Design of the Xiaomi Mijia Dispenser (models) MJJSQ01YL, MJJSQ02YL And analogs, it involves hidden latches and magnetic mounts that are not always obvious, and if you open them incorrectly, you can break the plastics or you can break the seal of the tank. We tested all methods in practice and collected step-by-step instructions taking into account typical user errors.

If you’ve just bought a dispenser or are planning to refill it, this article will help avoid common problems. For owners of models with touch button and wireless charging (Mijia Smart Liquid Dispenser Pro), we have added separate recommendations, as their design is different from the basic version.

1. Preparation for opening the dispenser: what to do in advance

Before disassembling, make sure the device is powered off (if a network adapter is used) or remove the batteries, which will prevent the motion sensor or touch button from accidentally triggering during manipulation, and prepare the following tools and materials:

  • πŸ”§ Plastic blade or mediator (to separate latches)
  • 🧴 Clean fabric or wipes (for cleaning internal surfaces)
  • πŸ’§ Distilled water or alcohol (to clean contacts if required)
  • πŸ“¦ Residue soap drain container (if the tank is not empty)

If the dispenser is connected to the Mi Home app, we recommend that it be disconnected from the Wi-Fi network for service duration, which will eliminate false automation alarms (for example, if you have a low fluid alert set up).

⚠️ Warning: Do not use metal objects (screwdrivers, knives) to open the case! Xiaomi Mijia plastic is fragile enough, and scratches or chips easily remain on it.

If you are filling the dispenser for the first time, please note that the manufacturer recommends using a liquid soap with a viscosity of no more than 500 mPaΒ·s (usually indicated on the package), too thick gels or shampoos can clog the pump and shorten the life of the device.

πŸ’‘

Before refilling the new soap, wash the tank with warm water with the addition of vinegar (1:10) - this will remove the residues of the previous remedy and prevent the formation of sediment.

2.Official method of opening: instructions from Xiaomi

The Xiaomi Mijia user manual describes the standard disassembly method that is suitable for most models.

  1. Place the dispenser on a flat surface with the top part (with a button) up.
  2. Press the lower part of the body (where the tank is located) and simultaneously pull it down with a little effort.
  3. If the latches do not lend themselves, slightly swing the lower part left-right, without putting excessive effort.

Ideally, the case should be divided into two parts: the upper (with electronic filling) and the lower (liquid reservoir), but in practice, many users find that the latches β€œstick” over time, especially if the dispenser is not opened for a long time.

What to do if the body does not open?
If the standard method does not work, the cause may be: - Distortion of the latches (for example, after the device falls). - Drying of soap at the joints, which creates additional resistance. - Production defect (rarely, but occurs in early batches). In such cases, try the methods in the next section.

After the successful opening, you will see the internal structure:

  • πŸ”‹ Battery or battery compartment (depending on model).
  • πŸ’§ Silicone tube pump.
  • πŸ“Ά Motion sensor (in models with automatic dosing).

⚠️ Attention: Do not touch the pump contacts with wet hands! This can cause short circuit. If cleaning is required, use a cotton swab soaked in alcohol.

3. Alternative methods of opening (if the standard does not work)

If the body does not lend itself, try one of the proven methods:

Method 1: Heating of the housing

Plastic latches can stick due to temperature changes. Place the dispenser in a warm place (for example, next to the battery) for 10-15 minutes or use a dryer at minimum power, holding it at a distance of 20 cm.

Method 2: Using a plastic shoulder blade

Carefully insert the blade into the gap between the top and bottom of the body (starting at the corner), and slowly lead it along the perimeter, snapping the mounts. Don't push too hard - light enough pressure.

Shut down the power.|Prepare tools|Heat the body (if necessary)|Use a plastic spatula|Pull the lower part down after snapping-->

For the Mijia Smart Liquid Dispenser Pro with magnetic mounting:

  1. Turn the lower part counterclockwise by 10-15 degrees.
  2. Pull her down with a slight motion.

If none of these methods worked, it is possible that the dispenser needs professional repair, in which case, contact the Xiaomi service center or the trusted smart technicians.

4. Filling the dispenser: rules and errors

Once the opening is successful, you can start refueling.

  • 🚫 Do not pour the liquid above the maximum mark (usually 300-350 ml.
  • πŸ”„ For even distribution of soap slightly sway the dispenser after refilling.
  • 🧼 Use only liquids without abrasive particles (scrabs, gels with microbeads clog the pump).

If you use concentrated soap, dilute it with water in a 1:1 ratio, which will prolong the life of the pump. For models with flavoring (Mijia Aromatic Liquid Dispenser), you can add essential oils (no more than 5 drops per 300 ml).

Type of soapCompatible with Xiaomi MijiaRecommendations
Liquid soap (viscosity up to 500 mPaΒ·s)βœ… It fits.The best option for all models
shower gel⚠️ Conditionally.Dilute with water 1:1, avoid thick gels
Antiseptic (alcohol)❌ Not recommendedEating away silicone sealers
Hair shampoo⚠️ Conditionally.Only liquid formulas without sulphates

⚠️ Warning: After filling, be sure to check the leakproofness by turning the dispenser down for 10 seconds. If the soap does not leak, the assembly is done correctly.

5. Cleaning and maintenance: how to extend the life of a dispenser

Regular cleaning prevents clogging of the pump and maintains hygiene, the recommended frequency is every 2-3 months (or more often if you use flavored products).

  1. Pour the residues of soap and rinse the tank with warm water.
  2. Remove the silicone pump tube and rinse it under running water (you can use a syringe for pumping).
  3. Wipe the motion sensor (if any) with a dry wipe - getting moisture can disrupt its operation.
  4. Leave all the parts to dry in the air for at least 2 hours.

To remove lime plaque (relevant to regions with hard water), use a solution of citric acid (1 tbsp. spoon per 200 ml of water). Pour it into the tank for 30 minutes, then thoroughly rinse.

πŸ’‘

Never use aggressive detergents (such as Domestos) to clean the insides of the dispenser! they break down plastic and silicone seals.

If the pump has stopped pumping soap, check:

  • πŸ”Œ Connecting the tube to the pump (sometimes it jumps off when cleaning).
  • πŸ”‹ Battery charge (at low charge, the pump can work intermittently).
  • 🚫 Filter clogging (in some models it is located at the pump entrance).

6. Assembly of the dispenser: how to avoid errors

After refueling or cleaning, assemble the device in reverse order:

  1. Make sure the silicone tube is tightly put on the pump.
  2. Line the lower part of the body along the grooves of the upper.
  3. Press the bottom part until the characteristic click (all latches should work).

For the Mijia Pro model with magnetic mounting:

  1. Put the tags on the body.
  2. Turn the lower part clockwise until fixing.

⚠️ Attention: If after assembly the dispenser does not turn on, check: - Correct installation of batteries (polarity!). - Contacts of the battery (if necessary, clean them with alcohol). - Tightness of the tank - sometimes the fluid level sensor blocks work during leaks.

After assembly, perform a test run:

  1. Put your hand in the sensor (or press the button).
  2. Make sure the soap is served evenly, without jerking.
  3. Check the indication in the Mi Home app (if connected).
