How to disassemble the dispenser Xiaomi: instructions for all models of a smart home

Xiaomi dispensers are popular smart home devices that automate plant watering, animal feeding, or dosed detergent delivery. Over time, dust, residues of liquids or feed accumulate inside the mechanism, leading to jamming or inaccurate work. Disassembly of the dispenser may be required to clean, lubricate machinery, or even replace broken parts.

In this article, we will discuss in detail the process of disassembling the Xiaomi MiJia, Aqara and Yeelight dispensers (including models for plants, feed and household chemicals), you will learn what tools you will need, how to avoid breakdowns during dismantling and what to do if the device stops working after assembly, and special attention will be paid to models with servos – their mechanism is most vulnerable to improper disassembly.

What Xiaomi dispensers can be disassembled independently?

Not all Xiaomi dispensers are disassembled at home; the manufacturer often uses glue or ultrasonic welding to seal the case, especially in budget models; however, most mid- and premium devices are disassembled using standard tools.

Here is a list of models that can be serviced on their own:

• 🌱 Xiaomi MiJia Plant Smart Doser (for fertilizers and irrigation)
• 🐶 Aqara Pet Feeder (Automatic feeder)
• 🧼 Yeelight Smart Detergent Dispenser (for detergents)
• 💧 Xiaomi MiJia Watering Timer (watering timer with dispenser)

If your model is not on the list, check for screws on the body or latches under rubber legs. The absence of visible mounts usually means that the body is glued or welded.

Preparation for disassembly: tools and security measures

Before you start dismantling, prepare the workspace and tools.

• 🔧 Setting screwdrivers (PH0, PH1, T5, T6)
• 🔨 Plastic mediator or guitar mediator (to separate latch)
• 🧲 Magnetic screwdriver or tweezers (so as not to lose small screws)
• 📸 Smartphone for photographing the process (useful when assembling)
• 🧴 Alcohol or isopropyl alcohol (for cleaning contacts)

⚠️ Note: If the dispenser is connected to the network 220V (For example, Yeelight Smart Detergent Dispenser, be sure to disconnect it from the socket 10-15 minutes before disassembly. The capacitors can store charge, which will lead to an electric shock when you touch the board.

Also prepare containers for small parts (like plastic bottle caps) and soft fabric to avoid scratching the body. If you disassemble a liquid dispenser, drain the remaining contents in advance - some models have hidden valves that can open when dismantled.

Step-by-step disassembly of the Xiaomi dispenser (universal instructions)

The disassembly algorithm for most models is similar, but there are nuances depending on the type of dispenser. Below is a universal instruction, suitable for the MiJia Plant Smart Doser and Aqara Pet Feeder.

Step 1 - Dismantling the bottom cover

Turn over the dispenser and look at the bottom. Most models have the lid attached to:

• 🔩 Screwdriver (usually under a cross screwdriver) PH1)
• 🔗 Latches (need to be carefully tampered with the mediator)
• 🧲 Magnets (found in premium models such as Yeelight)

If the screws are hidden under legs or stickers, carefully remove them with a knife or tweezers.Do not use metal tools - they can scratch the plastic.

Step 2. Unplug the top panel

When you remove the bottom cover, you'll see the interior design. In servo models like the Aqara Pet Feeder, the top panel is usually attached to the base using:

• 🔄 Turning mechanism (must be turned counterclockwise)
• 🔗 Plastic latches (poked by the mediator)

Be careful: in some dispensers, the top panel is connected to a sensor wire (for example, a fluid level sensor). Don't pull it by force, first disconnect the connector.

Step 3: Extract the dosage mechanism

The heart of the dispenser is a gear mechanism or servo drive, which is usually removable in feed models (Aqara), and in liquid dispensers (Yeelight) it can be integrated into the body to extract it:

1. Turn the stainless stains away (if any).
2. Carefully pull the mechanism upwards, holding the body.
3. If the mechanism fails, check for hidden latches.

⚠️ Note: In the dispensers Xiaomi MiJia with Wi-Fi function, the control board can be glued to the body with double-sided tape. Do not tear it off by force - warm up with a hair dryer (temperature not higher than 60).°C) and gently apply.

Features of disassembling specific models

Each model of Xiaomi dispenser has unique design features, and the key differences for popular devices are listed below.

For the Yeelight Smart Detergent Dispenser, disassembly is complicated by ultrasonic welding, and if you're not sure about your skills, you should contact the service, otherwise, with care, you won't have any problems.

💡

If the screws don't twist, drop a little on them. WD-40 It'll help dissolve any corrosion or dried lubricant that might be present.

Cleaning and lubricating mechanisms: what can and cannot be done

After disassembly, it is time to clean and lubricate the parts, but not all methods are safe for Xiaomi dispensers.

✅ Permitted:

• 🧹 Cleaning of gears and servo drive with isopropyl alcohol (at least 90%)
• 🛢️ Lubrication of plastic parts with silicone lubrication (for example, WD-40 Specialist)
• 🧽 Washing tanks with warm water and soap (for models without electronics)

❌ Forbidden:

• 🚫 Use of abrasive materials (sandpaper, metal brushes)
• 🚫 Lubrication with machine oil or lithole – they attract dust
• 🚫 Immersion board in water (even if it is in a silicone case)

Pay special attention to rubber sealing rings (if any) can be washed with water, but before assembly be sure to dry and lubricate with food silicone (for feeders) or glycerin (for liquid dispensers).

💡

Never use vegetable oil or petroleum petroleum petroleum to lubricate the dispenser mechanisms - they thicken over time and lead to a spell.

Constructing the dispenser: how to avoid mistakes

Building is as important as disassembly, and the rule of thumb is to follow the reverse sequence and check each step.

1. Checking seals

If the dispenser has rubber pads (e.g. Yeelight Smart Detergent Dispenser), make sure they are properly installed and not twisted.

Connecting connectors

In electronic models (Wi-Fi/Bluetooth) Make sure all the connectors are connected before you click:

• 🔌 Power connector
• 📶 Wi-Fi antennas (if any)
• 🔋 Liquid/feed level sensor

3. Test run

After assembly, do not rush to fill the dispenser immediately with liquid or feed.

1. Connect the device to power.
2. Run the test cycle through the Mi Home app.
3. Check if there are any extraneous sounds (squeaking, knocking).

⚠️ Warning: If the dispenser fails to turn on or is not working properly after assembly, check: Polarity of battery connection (if the device is battery-powered); Wire integrity (possibly touched during assembly); Errors in the Mi Home application (sometimes you need to reset settings).

Frequent breakdowns after disassembly and how to eliminate them

Even with a careful disassembly, there is a risk of problems, and here are the most common ones and ways to solve them:

If the device is not identified in Mi Home after disassembly, try:

1. Reset the dispenser settings (usually the Reset button on the board).
2. Reinstall the Mi Home app.
3. Connect your device to another Wi-Fi network (sometimes changing the region in your application settings helps).

If the problem is not solved, the firmware may be damaged, in which case you will need to flash through the firmware. USB-cable (instructions are available on the forums) 4PDA Xiaomi Community).
