How to properly fill the touch dispenser of soap Xiaomi: instructions with photos and tips

Why You Need a Soap Sensor Dispenser and How It Works

Xiaomi’s liquid soap touch dispensers (such as the Mijia Smart Soap Dispenser or Viomi Smart Soap Dispenser) have become a popular bathroom and kitchen gadget. They automatically give away a portion of the detergent when you put your hand up — without touching it, which is hygienic and convenient. But many users are faced with the problem of how to properly refill the device so that it works without malfunctioning.

Unlike conventional mechanical dispensers, Xiaomi smart models require careful refueling. Incorrectly selected soap, overflow or contamination of the sensor can lead to leaks, clogs or sensor failure. In this article, detailed instructions with nuances that are not specified in the official manual.

We'll take it apart.

• 🧼 Which Soap is Good for Sensory Dispensers (and Which Is Not)
• 🔧 How to disassemble and refuel the device without breakdowns
• 🚿 How to avoid common errors (leaks, foam in the mechanism)
• 🔄 How to clean the dispenser if it stops working

Before you go to the instructions, check the model of your dispenser. Most tips are universal, but some nuances depend on the design. For example, in the Viomi V-SD01, the tank is removed differently than in the Mijia MJSDJ01YL.

What soap can be poured into the dispenser Xiaomi – and what not

Not all detergents are compatible with touch dispensers. The manufacturer recommends using a 1,000-3,000 mPa·s viscosity liquid soap (roughly like a shower gel). Too thick or liquid formulations cause failures:

• ✅ Suitable: Liquid hand soap (Dove, Palmolive), antibacterial gels, shampoos marked "for dispensers"
• ⚠️ With caution: shower gel (may foam), liquid for washing dishes (corrodes seals)
• ❌ Not suitable: hard soap, soap chips, products with abrasives or solvents (acetone, alcohol) >10%)

The critical nuance is that Xiaomi dispensers are not designed for particle dispensers (scrabs, peeling gels). They clog the pump and knock the device out. If you use perfume soap, check if it leaves a sticky sludge, it will speed up the contamination of the sensor.

The best option is the original Xiaomi soap (MJSDJ01YL-SOAP), but it is more expensive than its counterparts. The alternative is to dilute the thick gel with distilled water (1:1) and test for fluidity.

⚠️ Warning: If the dispenser gives out soap in jerks or late after refueling, then the viscosity of the product is not suitable.

Step-by-step: how to fill the dispenser of soap Xiaomi

Before refueling, disconnect the dispenser from the mains (if it is powered by an outlet) or remove the batteries, which will prevent the pump from accidentally operating.

Shut down the power.

Prepare soap (compatibility checked)

Place the dispenser on a flat surface

Prepare napkins (in case of strait)-->

1. Remove the top cover. Most models have latches on them, press them on both sides or pull the top up. In the Viomi V-SD01, the lid turns counterclockwise.
2. Remove the tank. In models with the pump at the bottom (for example, Mijia MJSDJ01YL), the tank is removed whole. In dispensers with the top pump (Viomi), only the lid.
3. Wash the tank (if you're refueling for the first time or changing the type of soap). Use warm water without detergents.
4. Fill the tank to the edges — leave 1-1.5 cm to the top, otherwise the pump will "grab" air.
5. Put the tank back in. Make sure it's firmly settled in place, or there's a possibility of leaks.
6. Close the lid and turn on the power. Swipe your hand over the sensor, and you'll get a test soap.

If the dispenser does not give out soap after filling:

• Check if the tank is properly installed (a common mistake is skewed landing).
• Make sure the soap is not too thick (try diluting it with water).
• Reboot the device (remove the batteries for 10 seconds).

💡

If the soap comes out with bubbles, before filling, let it sit for 1-2 hours in an open container. This will remove the excess air.

Cleaning the dispenser: how to eliminate blockages and leaks

Even with the right soap, the dispenser requires cleaning every 1-2 months.

• 🔴 The soap is dispensed intermittently or drips after use.
• 🔴 Sensor goes off again.
• 🔴 There's a slack on the body.

You'll need warm water, a soft toothbrush, cotton swabs, vinegar solution (1:1 with water), or glass washing. Don't use abrasives or alcohol!

Pay particular attention to:

• 📍 Sensor: wipe it with a dry wipe. Dust or soapy dilution interferes with the operation.
• 📍 O-ring: if it is deformed, replace (parts sold on AliExpress on request "Xiaomi soap dispenser gasket").
• 📍 Pump inlet: often clogged with soap sludge.

⚠️ Attention: If the dispenser leaks after cleaning, check the integrity of the tank. In cheap models, the plastic cracks over time. The solution is to replace the tank or the entire device.

Common Mistakes and How to Avoid Them

Most of the problems with Xiaomi dispensers are due to improper operation.

• 🚫 Pour soap under the neck. When heated (for example, in the bathroom), the liquid expands and flows out through the seals.
• 🚫 Use bleach products that corrode plastic and damage the sensor.
• 🚫 Put the dispenser in direct sunlight, UV radiation makes plastic brittle.
• 🚫 Ignore leaks. If soap leaks through the bottom, disassemble the device immediately, which is a sign of seal wear.

Another common mistake is to flip the dispenser to drain soap. In lower-pump models (Mijia), this results in liquid entering the electronic unit. To drain the soap, use a syringe or tilt the device at a 45-angle angle.°.

If the dispenser stopped working after refueling, check:

1. Did not get moisture on the board (a characteristic sign - the indicator flashes, but the pump does not work).
2. Do you have a stained hole (or a stained one)?
3. Are the batteries dead (even if the indicator is on, the power may not be enough for the pump).

💡

If the dispenser gives out soap in jerks, it's likely that air has entered the tank, so you can drain some of the soap, shake the device, and refill the liquid to the desired level.

How to extend the life of the dispenser: tips for care

With proper care, the Xiaomi touch dispenser will last 3-5 years.

• 🔄 Change the soap every 1-2 months. Even quality products will form a precipitate over time.
• 💧 Use distilled water to dilute. Tap water leaves a limestone plaque.
• 🔋 Remove the batteries if you don't use the dispenser for longer than a week, and this will prevent contact corrosion.
• 🧴 Store spare soap in sealed containers. Contact with air worsens fluidity.

For models with lighting (for example, Viomi) V-SD01) avoid getting moisture on LED-If the indicator starts flashing randomly, dry the device for 24 hours (without batteries).

If you use a dispenser in the kitchen, protect it from oil sprays — they clog the sensor. Solution: Set the device 30-50 cm from the stove or use a protective visor (you can cut out of a plastic bottle).

What to do if the dispenser broke: diagnosis and repair

If the dispenser stopped working, first identify the symptom:

If the dispenser does not turn on at all:

1. Check the batteries (even new ones can be discharged).
2. Examine the contacts for corrosion (clean with alcohol if there is oxidation).
3. Try resetting (in some models, hold the power button for 10 seconds).

For USB-powered models (Viomi), check the power supply – it should give exactly 5V/1A. Using a charge from the phone (current >1A) can burn the board.

⚠️ Warning: If the pump is squeezing or not rotating after flushing, don't try to disassemble it, which requires replacement in 90% of cases, MJSDJ01YL-PUMP for Mijia).
