Analysis of the washing machine Xiaomi: a step-by-step guide with photos and nuances

Xiaomi washing machines have gained popularity due to a combination of affordable prices, modern technology and compact sizes. However, even the most reliable equipment sometimes requires repairs - whether it is replacing bearings, cleaning the drum or diagnosing electronic components. Disassembling the car at home allows you to save on the service center, but requires accuracy and knowledge of the design features of MiJia or Viomi models.

In this article, we will discuss in detail the process of disassembling a Xiaomi washing machine – from tool preparation to removal of key nodes. Particular attention will be paid to the typical errors of beginners that can lead to damage to equipment, and also give recommendations for diagnosing malfunctions before the start of dismantling. If you have never dealt with home appliance repair, start by studying the structural scheme of your model – this will help to avoid unnecessary actions.

Important: Disassembly procedure may vary slightly depending on the specific model (e.g. Xiaomi MiniJ or Viomi). V3). All of the steps below are relevant for vertical and front loading machines built after 2018.Over-dated versions (before 2017) may require additional information.

Preparation for disassembly: tools and security measures

Before you start disassembling, make sure you have everything you need, and not even one tool can delay the process or damage plastic parts, and here's the minimum set you'll need:

• 🔧 Screwdrivers: cross (PH2, PH3), flat (3-5 mm), torx (T20, T25) — The latter are often used in Viomi models for mounting the back panel.
• 🔨 Wrecks: carob or cape on 8, 10 and 13 mm - for removing counterweights and shock absorbers.
• 📸 Smartphone or camera: capture each stage of disassembly, especially the location of the wires and fasteners.
• 🧲 Magnetic pallet or bowl: for storing small parts (screws, nuts) so that they do not get lost.
• 🧽 Mulch and containers: to collect residues of water from hoses and tank.

Pay special attention to safety:

⚠️ Warning: Before disassembling, be sure to disconnect the car from the network and close the water supply. Even when switched off, the control board capacitors can retain a charge of up to 300 V - touching them with your bare hands is dangerous!

If you are disassembling a machine to repair electronic components (such as changing a control board), use an antistatic bracelet or periodically touch grounded metal surfaces to remove static electricity. For models with an inverter motor (such as the Xiaomi MiniJ Pro), it is also recommended to discharge high-voltage capacitors by closing their terminals with a screwdriver with an insulated handle.

If the car was in use, prepare a place for disassembly: lay on the floor a cardboard or an old blanket, so as not to scratch the case and not lose small details. The best option is to disassemble the equipment in the garage or on the balcony, where there is enough space for the layout of the knots.

Removing the upper and back cover: the first steps

Start disassembling by removing the top panel, which is the easiest step to open up access to the internal components. In most Xiaomi models, the top cover is mounted with two screws at the back and fixed with latches at the front.

1. Unscrew two screws on the back of the car (usually under plastic plugs).
2. Move the lid back to the back carefully. 1-2 see to free it from the front latches.
3. Lift the lid up and remove it. In some models (e.g. Viomi). V3) Additional effort may be required due to a tight landing.

Once you remove the top panel, you'll see counterweights (concrete or plastic blocks), tank suspension springs, and some electrical wiring. Take your time to remove them -- first unscrew the back cover to access the engine and drain pump.

The back panel is attached. 4-6 Xiaomi MiniJ cars often use torx screws (depending on the model). T20, In Viomi, you have a cross screwdriver, and after you unscrew the screws, you can pull the panel gently over you, and it can stick to the sealer, and if the lid doesn't lend itself, make sure there are any undetected fasteners on the sides.

At this point, you may encounter the first challenge: boiling screws. If the fastener doesn't unscrew, don't put too much effort into it -- lubricate it with penetrating lubricant (e.g., grease, WD-40) and wait 10-15 Use a screwdriver as a last resort, but be careful: if you tear the splints, you risk damaging the screw head.

Dismantling of the front panel and hatch: features of models with front loading

Removing the front panel is the most time-consuming step, especially for front-loading machines (such as the Xiaomi MiniJ Pro). It is important not to damage the seal cuff and hatch lock.

• 🔧 Unscrew the screws holding the control panel (usually) 2-3 top-and-side).
• 📱 Disconnect the wire connectors from the control board. Remember or photograph their location - the wrong connection can knock the board out of order.
• 🚪 Remove the cuff holding the seal cuff. In Xiaomi models, it can be spring-loaded or plastic with a latch.
• 🔄 Carefully bend the cuff inside the drum to free the front panel.

Pay special attention to the hatch blocker (UBL). In Xiaomi machines, it is often attached to the front panel and connected to a three-wire control board. When dismantled, don't pull the wires - unplug the connector by pressing the lock. If the lock is broken, use tweezers to gently pull the contacts out.

For models with a touch panel control (for example, Viomi) V3) Be careful with plumes - they are fragile and can come off if you do not handle it carefully. If the panel does not detach, check for hidden latches under decorative linings.

⚠️ Attention: In some Xiaomi cars, the front panel is connected to the body not only with screws, but also with plastic clips. When you take them off, they break, and you can't replace them separately - you have to buy the entire panel!

Once you remove the front panel, you will have access to the drum, TEN and shock absorbers, and at this stage, you can conduct a preliminary diagnosis: check the integrity of the wiring, inspect the drum for cracks or rust, and make sure that the shock absorbers do not leak (this indicates that they need to be replaced).

Removal of the tank and disassembly of internal nodes

The tank is the central element of the washing machine, and its dismantling requires caution. In Xiaomi models, the tank is usually collapsible (consisting of two halves), which makes it easier to replace bearings or osteoils.

1. Disconnect all wires from the TEN, the engine and the water level sensor (pressostat).
2. Remove the counterweights – they are bolts 10 or 13 mm. Be prepared for their weight: in cars Viomi counterweights can weigh up to 10 kg.
3. Unscrew shock absorbers and suspension springs. In some models, the springs have left threads -- unscrew them counterclockwise.
4. Carefully remove the tank from the body by pulling it up, and if the tank jams, make sure you have forgotten to disconnect the drain pipe or vibration sensor.

Once the tank is removed, it must be disassembled to access bearings or a drum. In Xiaomi cars, the halves of the tank are fastened with bolts around the perimeter (usually 6-8 And a sealant:

• 🔧 Turn all the bolts around. If they're stuck, use penetrating lubricant.
• 🔨 Carefully separate the halves of the tank, putting them in a flat screwdriver. Do not make excessive efforts - plastic can crack.
• 🧹 Remove the residue of the sealant with a scraper or solvent (e.g., White Spirit).

Inside the tank, you'll find a drum, a bearing assembly and a gum.

If you want to replace bearings, pay attention to the labeling. Xiaomi MiniJ cars often use bearings. 6204-2RS (domestic 6205-2RS (For Viomi models, you may need different sizes — check this out in advance. When installing new bearings, use a special lubricant for washing machines (for example, Liqui Moly Thermoflex) rather than a regular lithole.

Diagnostics and replacement of electronic components

If the machine is disassembled due to malfunctions of electronic components (for example, the display does not turn on, the pressing or drain does not work), pay special attention to the control board, sensors and the engine. In Xiaomi cars, electronics often become the “weak link” due to voltage surges or moisture.

Start by inspecting the control board (usually located under the control panel or on the side of the case).

• 🔥 Blackened or swollen capacitors.
• 💧 Traces of oxidation or corrosion (indicate moisture intrusion).
• 🔌 Burnt tracks or connectors.

To check the fee, use a multimeter:

1. Call the power chains for breaks.
2. Check the resistance of key elements (resistors, transistors).
3. Make sure there is no short circuit on the connectors.

If the board is damaged, you can try to repair it (replace the capacitors, lose tracks) or replace it with a new one.The original boards for Xiaomi MiniJ cost from 3000 to 5000 rubles, but often suitable analogues from Viomi or other brands with the same series of boards (for example, Midea).

Also check:

• 🔋 Water level sensor (pressostat): blow into a tube connected to the sensor, a click should be heard. If it is not, the sensor is defective.
• 🌀 Engine: Check the resistance of the windings (should be within the limits of the 10-30 If the engine is buzzing but not rotating, the problem may be the brushes or the tachodilator.
• 🌡️ TEN: The resistance between the conclusions must be 25-40 Oh, if the multimeter shows"1" (break"0" (short circuit, the heater must be replaced.

⚠️ Note: In Xiaomi cars with an inverter engine (for example, MiniJ Pro) it is not recommended to disassemble the engine yourself - its repair requires special equipment to flash the controller.

💡

Before you replace the electronics, turn off all the connectors and take a picture of their location. When you connect a new board, start with the power connectors, then connect the sensors, and last but not least, the display.

Building the car after repair: key points

Building a Xiaomi washing machine after repair is as important as disassembling, and the rule of thumb is to collect it in reverse order, following the photos you took.

• 🔧 Tightening fasteners: don't pull over the bolts - this can cause cracks in the plastic tank or deformation of the body.Use a dynamometer key (puff-up moment for most bolts — 8-12 N).
• 🧴 Tank sealing: When assembling the halves of the tank, apply a new sealant (for example, ABRO 11-AB) Excess sealant can get in and damage the drum.
• 🔌 Wiring connection: make sure all seated connectors are up to click, especially the engine connectors and the control board.
• 💧 Leak check: after assembly, run a test wash without laundry to make sure there are no leaks.

Pay special attention to the balancing of the drum, and after the bearings or shock absorbers are replaced, the machine can vibrate very strongly when pressed.

1. Make sure that the counterweights are installed symmetrically and securely.
2. Check the suspension springs – they should be equally stretched.
3. Run a test wash with an empty drum on the program "Push" (800-1000 If the vibration is strong, recheck the mounting of the shock absorbers.

If the machine fails to turn on or fails to work after assembly, don't panic.

• Unconnected control board connector.
• Incorrectly installed water level sensor.
• Closes in the wiring (check with a multimeter).

To reset errors in Xiaomi machines, try to turn off power on 10-15 If the error persists, please refer to the section. FAQ Check the code of the malfunction in the instructions.

💡

After assembly, be sure to run the test wash on the program "Fast 30".°" This will test the leakage, balance and performance of electronic components.

Common Mistakes in Disassembly and How to Avoid Them

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

Another common problem is the loss or confusion of fasteners, with Xiaomi machines using different lengths of screws (e.g., to fasten control boards and balances) to avoid errors:

• 📦 Store screws in separate containers with signatures (for example, "Control Panel", "Control").
• 📏 Measure the length of the screws before unscrewing and mark them.
• 🔍 Use a magnetic mat to avoid losing small details.

If you are disassembling a cleaning machine (for example, from scale or mold), avoid aggressive chemicals. For plastic parts (tank, powder tray), use citric acid or specialized means (for example, Sano Antikalc). For metal parts (drum, TENG), Cillit Bang is suitable against scale. Do not use abrasive sponges - they scratch the surface.
