Disassembly of the air humidifier Xiaomi Antibacterial: instructions with photos and nuances

Xiaomi Smartmi Air Humidifier Antibacterial (models) JSQ01ZM, JSQ02ZM And it's a popular device for maintaining optimal microclimate, but over time, even the most reliable technology requires cleaning or repair, clogged membranes, oxidized contacts, or stopped working ultrasonic generator. You can disassemble the Xiaomi humidifier yourself, but it is important to do it carefully so as not to damage fragile parts.

In this article, you will find step-by-step instructions with the photo, a list of necessary tools, and critical nuances that the manufacturer does not specify in the official documentation. We will learn how to remove the bottom cover without damage, get to the electronic board and membrane, and what to do if the device stopped turning on after disassembly, and pay special attention to the antibacterial module, a key element that often fails when used improperly.

We warn you right away: disassembling the Xiaomi humidifier is not warranty if it is still valid. If the device is warranty, you should contact the service center. For everyone else, go to the step-by-step guide!

Preparation for disassembly: tools and security measures

Before you start, make sure the humidifier is completely off the grid and the water from the tank is drained, and even the residual moisture on the contacts can cause a short circuit when disassembling.

• ✅ Plastic blade (mediator) or guitar mediator - for careful grazing of latches.
• ✅ Cross screwdriver (usually) PH0 or PH1) — board-pin.
• ✅ Tweezers – to extract small parts (such as silicone pad).
• ✅ Isopropyl alcohol (70%+) — purifier.
• ✅ Soft fabric without pile - to wipe the internal surfaces.
• ✅ Hair dryer (optional) - to dry parts after cleaning.

⚠️ Warning: Never use metal screwdrivers or knives to tweak plastic latches! Xiaomi uses a fragile one ABS-If the latch doesn't lend itself, don't force it, but check if all the screws are twisted.

Also, prepare your workspace: put a soft cloth or towel in order not to scratch the case or lose small parts. If you're disassembling the device for the first time, take a picture of each step, which will help you put it back together properly.

Removal of the upper cover and water tank

To start with, the simplest thing is to remove the top. In Xiaomi Antibacterial models, the lid is mounted on 4 latches (two on each side) and one central latch.

1. Turn the humidifier to your top.
2. Carefully insert the plastic blade into the gap between the lid and the base on the right side (when looking at the device from the front).
3. With a light press, click the first latch. Repeat the same thing on the left side.
4. After the side latches are freed, pull the lid up and slightly on yourself - the central retainer should come out of the groove.

If the lid fails, check to see if additional latches have gone unnoticed, JSQ02ZM) There may be a fifth latch on the back, and it's easy to miss.

When you take the lid off, you'll see a water tank that's not screwed, but sits tightly on a silicone pad to extract it.

1. Carefully pull the tank upwards, swaying slightly from side to side.
2. If it does not go, check if the pad is stuck to the base (you can tweez it with tweezers).
3. After extraction, inspect the gasket for cracks or deformities. If it is damaged, it should be replaced (article for ordering: XMSH01ZM).

Access to electronic board and ultrasonic membrane

Now, the most important part is disassembling the base, where the electronic circuit board and the ultrasonic membrane are located, and the main thing is to take your time and keep an eye on the power wires, which are easy to tear off.

First, turn the base of the humidifier upside down, and you'll see 4 rubber legs, and there are screws underneath, and you'll be careful to put the legs in a flat screwdriver and remove them. There'll be screws underneath. PH0 — unscrew them.

After removing the bottom cover, you will see:

• 🔋 Electronic board with control chip (usually marking) SM2135 or SM2156).
• 💧 Ultrasonic membrane (a round metal disc) is the main element that creates fog.
• 🔌 Power connectors and sensors (humidity, temperature).
• 🦠 Antibacterial module (in models with the prefix Antibacterial) - usually silver or coated with a special composition.

⚠️ Warning: If you notice oxidation on the membrane contacts (green or white), this is one of the main reasons why the humidifier stops working!

Cleaning and diagnosis of the antibacterial module

Xiaomi Antibacterial has an antibacterial coating that loses its effectiveness over time, and if the humidifier starts to smell bad or the water in the tank blooms, the problem is with this module.

The antibacterial element is usually:

• 🧊 Silver rod (in older models) - oxidizes over time.
• 🧪 Ceramic filter with silver ions (in new models) – requires washing.
• 🧴 Special coating on the internal walls of the tank - not subject to restoration.

To clean the module:

1. Remove the antibacterial rod (if it is removable) and rinse it under running water.
2. To remove plaque, use citric acid (1 tbsp. spoon per 1 liter of water), but do not hold for more than 10 minutes.
3. Wash the ceramic filter under a stream of water, but do not rub with a brush - this will damage the coating.
4. If the module is not removable (for example, coating on the walls), pour vinegar solution (1: 1 with water) into the tank for 1 hour, then thoroughly rinse.

⚠️ Warning: After cleaning the antibacterial module, be sure to rinse the tank with distilled water.Citric acid or vinegar residues can damage the membrane the next time you turn on!

💡

If the humidifier still smells after cleaning, try boiling removable parts (except electronics!) in soda water (2 tablespoons per 1 liter) for 5 minutes, which kills bacteria that may have remained in the pores of the plastic.

Common breakdowns and how to fix them

If the Xiaomi Antibacterial humidifier doesn’t turn on, create fog, or is out of order, the reasons may be as follows:

One of the most common breaks is the failure of the ultrasonic membrane. If after cleaning, the fog does not appear, check:

• 🔌 Membrane power - multimeter measure the voltage on the contacts (should be ~24V).
• 🔊 Membrane integrity – inspect for cracks (even microcracks lead to loss of performance).
• 💡 Generator operation – if the membrane is intact but does not vibrate, the problem is with the control chip.

If the membrane is good but there is no fog, the holes in the sprayer may have clogged, and they can be cleaned with a needle or compressed air (for example, a can of keyboard cleaning).

💡

90% breakage of Xiaomi humidifiers are associated with contamination of the membrane or oxidation of contacts. 1-2 months) extends the life of the device in 2-3 once.

Remove the humidifier after disassembly

You need to take the humidifier back together as carefully as you take it apart.

1. Make sure all gaskets and seals are installed in their places. even a slight shift will lead to leaks.
2. When connecting the plumes to the board, check that the connectors sat down before clicking - uncooked contact can cause malfunctions.
3. Screw the screws cross-curl to avoid skewing the cover.
4. Before the first turn on after assembly, let the device stand 10-15 This is necessary to stabilize the pressure in the system.

⚠️ Warning: If the humidifier doesn't turn on or makes unusual sounds after assembly, disconnect it immediately from the network! you probably forgot to connect one of the sensors (for example, a water level sensor) or confused polarity when connecting the membrane.

After assembly, perform a test run:

1. Put distilled water (not tap water!) in the tank.
2. Turn on the device and check if fog appears through the 10-20 seconds.
3. Listen to the fan - it should rotate smoothly, without creaking.
4. Make sure there are no leaks in the joints of the cover and the base.

Prevention: how to prolong the life of a moisturizer

To avoid frequent disputes, follow these tips:

• 💧 Use only distilled or filtered water – hard water quickly clogs the membrane with a plaque.
• 🧼 Wash the tank once a week with a mild detergent (no abrasives!).
• 🔄 Change water daily, even if the humidifier is not used – stagnant water becomes a breeding ground for bacteria.
• 🌡️ Keep the device in a dry place – humidity above 60% contributes to the growth of mold inside.
• ⚡ Do not turn on the humidifier without water - this leads to overheating of the membrane.

If you live in a region with very hard water, consider installing an additional filter (e.g., Xiaomi Smartmi Filter, article). ZM-FILTER01). It retains salt and prolongs the life of the membrane.

💡

To test the hardness of the water at home, drop the drop on a black surface and let it dry. If there is a white trail, the water is hard and you can't pour it into a humidifier without filtration.
