Disassembly of the dispenser Xiaomi: from preparation to assembly without errors

Xiaomi dispensers are key components in the brand’s smart devices, from MiJia washing machines to Smartmi air humidifiers. They get contaminated, break down or require replacement seals over time, but official documentation rarely provides detailed disassembly instructions. This article will help disassemble the dispenser yourself, avoiding the typical mistakes of damaging latches, losing small parts or improper assembly.

We will look at the universal principles of disassembly (suitable for most Xiaomi models), as well as nuances for specific devices – for example, the dispenser of detergents in the washing machine Xiaomi MiJia. 1S Or a container for flavorings in a Smartmi Air Humidifier humidifier ZHJMA20M. Particular attention will be paid to tools that will not damage plastic, and hidden mounts that are not written about in standard manuals.

If you've never done a household appliance, don't worry, it's easier than it looks, and the key is to follow the logic of the design and not to exert excessive force. FAQ answering frequent questions, such as how to clean the dispenser of scale or what to do if the device does not work after assembly.

What Xiaomi dispensers can be disassembled independently

Not all dispensers in Xiaomi devices are disassembled at home, and here is a list of models where this is possible and appropriate:

• 🧺 Washing machines: MiJia 1S, MiJia Mini, Xiaomi MiniJ – dispensers for powder and air conditioning.
• 💧 Air humidifiers: Smartmi ZHJMA20M, Xiaomi MJJSQ — water-containers and aromacapsules.
• 🧴 Vacuum cleaners with washing function: Xiaomi Dreame W10, Mi Robot Mop 2 Pro – Reservoirs for detergent.
• ☕ Coffee machines: Xiaomi Viomi V3 — dispensers for coffee beans or capsules.

But the dispensers in Xiaomi robot vacuum cleaners (for example, garbage containers in Mi Robot Vacuum) are usually indissoluble – they are cleaned without dismantling. It is also not recommended to disassemble dispensers in smart diffusers (for example, Xiaomi Aroma Diffuser), since their body is glued together and is not designed for repair.

Before you start, check to see if the disassembly warranty will void. Most Xiaomi devices have warranty stickers glued to the dispenser screws - their damage deprives you of the right to free repair. If the device is no longer warranty, feel free to start!

Preparation: security tools and measures

You don't need professional equipment to disassemble Xiaomi's dispenser, but without the right tools, the risk of damaging plastic or losing small parts increases dramatically.

• 🔧 Screwdrivers: cross-hairdriver (PH2) flat (SL3.0) — most screws.
• 🔨 Plastic blades (mediators) - to disconnect latches without scratches.
• 🧲 Magnetic mat or bowl – so as not to lose screws and springs.
• 📸 Smartphone – Take photos of each stage of disassembly for reverse assembly.
• 🧴 Cleaning agent: vinegar (for scale), citric acid or specialized formulations such as Sano AntiCalc.

Be sure to disconnect the device from the mains! Even if the dispenser is mechanical (as in the washing machine), the residual charge in the capacitors can become dangerous. If you disassemble the humidifier, drain all the water and dry the tank for at least 24 hours, the moisture inside the electronic components will lead to corrosion.

⚠️ Warning: Don't use metal tools to smack plastic latches, they leave microcracks that eventually break down. If you don't have a plastic blade at hand, an old bank card will do.

If the dispenser is boiling (relevant to washing machines), do not try to pull it out by force. Soak it for 1-2 hours in warm water with added vinegar (proportion 1:1), then gently swing from side to side, which will help dissolve the lime deposits.

Step-by-step disassembly of the dispenser of the washing machine Xiaomi

The example of Xiaomi MiJia 1S Let's take the most complicated case, the powder and air conditioning dispenser, and it's designed with movable elements, springs and seals that are easy to lose.

Disconnect the car from the network and water supply|

Remove the dispenser from the compartment (click on the fixator in the center and pull on yourself)|

Towels - from the dispenser can leak the remaining water|

Prepare containers for small parts (screws, springs)-->

Step 1 Removing the top cover

Turn the dispenser upside down. Most Xiaomi models have the top cover attached to 2-3 plastic latches. Carefully tuck them in with a plastic blade starting at the corner of the air conditioning tray. Don't make any effort -- if the lid doesn't lend itself, you've missed the hidden latch (usually hidden under a logo sticker).

Step 2: Dismantling internal machinery

Under the lid, you'll see:

• 🔄 The turning mechanism - responsible for the supply of detergent.
• 🔗 The spring - returns the tray to its original position.
• 🛡️ O-ring – prevents leakage.

Take a picture of the parts, take the last spring, it can jump out and get lost, and the mechanism is usually mounted on a single screw (PH2) centre.

Step 3: Cleaning and replacing seals

Wash all the parts under warm water with a soft brush. To remove scale, use a solution of citric acid (2 tbsp. per 1 liter of water), dipping the parts for 30-40 minutes. The sealing ring cannot be cleaned with abrasives, this will lead to microcracks and leaks. If the ring has lost its elasticity, replace it with a new one (Article for MiJia) 1S — XMSH02FM).

Reverse the assembly. Make sure the spring is in place -- if it's skewed, the dispenser won't lock in the closed position. After assembly, check the tightness: pour the water into the tray and tilt the dispenser -- if the water doesn't leak, it's assembled correctly.

Disassembly of the air humidifier dispenser Smartmi

Dosers in Xiaomi Smartmi humidifiers (for example, ZHJMA20M) It's simpler in design, but they have their own nuances, and their main problem is limestone plaque and mold in hard-to-reach places.

Design features:

• 🔄 Rotating disc - doses the supply of water to the steam chamber.
• 🧽 Coarse cleaning filter - a grid that traps scale particles.
• 💧 Float valve - regulates the water level.

Disassembly instructions:

1. Remove the top cover of the humidifier, pulling it up (it is held on magnets).
2. Remove the water tank. The dispenser is at the bottom, under the steam chamber.
3. Unscrew 4 screws (PH1) Be careful, there may be springs underneath!
4. Carefully separate the upper part of the dispenser from the lower, pokeing a plastic blade along the contour.

Inside, you'll find a rotary disc and a filter.

• 🧽 Filter: wash under running water, with severe contamination soak in vinegar for 1 hour.
• 🔄 Disk: wipe with a soft cloth, lubricate with silicone lubricant (for example, WD-40 Specialist).

⚠️ Warning: Do not use hard brushes or metal scrapers to clean the dispenser of the humidifier, they will damage the antibacterial coating applied in the factory. If the coating has already worn off, after cleaning, treat the parts with a solution of chlorhexidine (0.05%).

After assembly, run the humidifier in Clean mode (if your model has one) or just let it work for 10-15 minutes with clean water to wash away the residues of cleaning products.

Frequent Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi dispensers, and here are the most common ones and ways to prevent them:

• 🔧 Rotor failure: occurs when you use the wrong size screwdriver. Xiaomi screws are usually suitable PH2 (cross-sectional SL3.0 (If the screw doesn't unscrew, drop it on it. WD-40 And wait 5 minutes.
• 🧩 Latch loss: Plastic locks often break when opened sloppy. Before disassembling, examine the design - sometimes the latches are hidden under stickers or rubber pads.
• 💦 Moisture in electronics: relevant for humidifiers. Always dry parts for at least 24 hours before assembly.
• 🔄 Incorrect assembly of the mechanism: if after assembly the dispenser is not fixed, check the position of the spring and rotary disc!

Another common problem is tug-of-war screws when you build them, which causes cracks in the plastic, twist the screws to a light stop, effortlessly. If the plastic does crack, use an epoxy adhesive (like the Loctite Plastics Bonding System), but remember, this repair is short-lived.

💡

If the screw in the dispenser is scrolling and does not twist, try to apply a heated soldering iron to it for 2-3 seconds. Thermocles, which sometimes fix the carvings in the factory, will melt, and the screw will be able to unscrew.

If the device doesn’t work after assembly (for example, the washing machine doesn’t draw water or the humidifier doesn’t turn on), check:

• 🔌 Connection of sensors (in humidifiers often leaves the connector of the float valve).
• 💧 Leakage of seals (leaks can block the work).
• 📱 Settings in the Mi Home app (sometimes after disassembly, error reset is required).

Cleaning and prevention: how to prolong the life of the dispenser

Regular cleaning of Xiaomi dispenser prevents 90% of breakdowns, here is the optimal prevention schedule:

Xiaomi washing machines are useful in running the drum cleaning cycle (available on most models menus), it removes scale not only from the dispenser, but also from the internal tubes. In humidifiers, use distilled water, which will reduce scale formation by 3-4 times.

If the dispenser began to smell unpleasant (relevant to humidifiers), the following procedure will help:

1. Pour into the tank a solution of hydrogen peroxide (3%) and water (1:1).
2. Let stand for 1 hour, then rinse with clean water.
3. Dry all the details in the sun (UV light kills bacteria).

Whiteness is suitable for disinfecting the disinfection of the washing machine (dilute 50 ml per 1 liter of water), but do not use it more often 1 time every 3 months - chlorine corrodes rubber seals.

Where to buy spare parts for Xiaomi dispenser

If you find faulty parts in the disassembly (a cracked tray, a spring that has lost its elasticity), you can replace them.

• 🛒 Xiaomi official store: on mi.com in the Parts section. Delivery is long (2-4 weeks), but the original is guaranteed.
• 🌍 AliExpress: Mi Store Official, Xiaomi Original Parts. Prices are lower, but check reviews - often come across fakes.
• 🏬 Local service centers: many Xiaomi repair shops sell used parts from donor devices.

When buying spare parts, pay attention to the article (found on the original part or in the documentation).

• For the MiJia washing machine 1S: sealing-ring — XMSH02FM, spring — XMSH03SP.
• For the Smartmi moisturiser ZHJMA20M: turn-plate — ZHJMA-DISK, filter — ZHJMA-FILTER.

The cost of spare parts usually does not exceed 500-1000 rubles, which is much cheaper than replacing the entire dispenser. If you are not sure about the choice, contact the Xiaomi support chat (in the Mi Home app) with a photo of the details - they will pick up the exact article.
