How to save the Xiaomi speaker, if it got water: proven methods

What to do if the speaker on Xiaomi wheezes or does not work after water hits?

You dropped a Xiaomi smartphone in water, spilled tea on it, or got caught in the rain — and now the speaker makes strange noises, wheezing or not talking at all? Don't panic: 80 percent of the time, the device can be saved without expensive repairs, the main thing is to act quickly and correctly.

Modern Xiaomi models (e.g. Redmi Note 12 Pro+, POCO F5 or Xiaomi 13T) have partial IP53 moisture protection. However, even such a certificate does not guarantee 100% protection: speakers remain one of the most vulnerable. In this article, 5 proven ways to dry the speaker, and what you can not do to avoid aggravating the situation.

Before you start taking action, assess the scale of the problem:

• 🔊 Weak wheezing when playing sound - water hit the speaker membrane, but did not penetrate deeply.
• 🔇 Quiet or distorted sound – moisture has accumulated in the speaker body or under the grid.
• 🚫 Complete lack of sound – possible short circuit or damage to contacts.

If Xiaomi doesn't turn on after contact with water, the problem goes beyond the speaker, in which case a full diagnosis is required at the service center. If the phone is working, but the speaker is floundering, read on.

Method 1: Use the built-in water blowing function (for new models)

Many modern Xiaomi smartphones (starting with MIUI 12.5 and later) have a hidden function of automatically blowing water out of the speaker, which activates after detecting moisture and emits a low-frequency sound that pushes the droplets.

How to start the function manually:

1. Connect your phone to charge (this is a must!).
2. Open the Settings app → The phone.
3. Click on the MIUI version several times until you become a developer!
4. Return to the main settings menu and select Additional → For developers.
5. Find the option to Remove water from the speaker (or Water Eject) and activate it.

If you don’t have this option, try an alternative method:

Enter the code in the phone application: ##36446337##


(It works on some POCO and Redmi models)

💡

If the function didn't work the first time, repeat the procedure in 10-15 minutes. Low-frequency vibrations help even when there is a lot of moisture.

Importantly, this is only effective for shallow water penetration, and if the fluid gets inside the housing through connectors or buttons, additional measures are required.

Method 2: Mechanical removal of water by vacuum or air

If the built-in function didn’t work, try physically blowing water out of the speaker, which would require a vacuum cleaner with a narrow nozzle or a can of compressed air (for example, to clean the keyboard).

Step-by-step:

• 🧹 Vacuum: Set the minimum power, hold the nozzle to the speaker at a distance of 1-2 cm and hold for 10-15 seconds. Do not touch the speaker grid with a nozzle - this can damage it!
• 💨 Canister with compressed air: short pulses (1-2 seconds) blow the speaker from a distance of 5-7 cm Keep the balloon strictly perpendicular, so as not to drive moisture deeper.
• 🔄 Repeat the procedure for both speakers (top and bottom) if they are available.

Turn off your phone (if it still works)

Remove the cover and film

Check that the charging connector is dry

Do not use a hair dryer (risk of overheating!)-->

⚠️ Warning: Never blow into the speaker with your mouth! saliva contains salts and acids that, when hit by contacts, can cause corrosion. Also avoid hot air (dryer, heater) - this deforms the speaker membrane.

After purging, put the phone down on a dry wipe and leave it for 1-2 hours, which will help the moisture residue drain under the influence of gravity.

Method 3: Absorption of moisture with silica gel or rice

One of the most famous (but not always effective) ways is to put the phone in adsorbent. Silicagel (those little bags of shoeboxes) absorbs moisture 10 times better than rice, but if it's not on hand, rice will do, too.

How to properly dry your phone in adsorbent:

• 📦 Preparation: Turn off your smartphone, pull out SIM-card and memory card (if any).
• 🌾 Adsorbent selection: Fill a sealed package (e.g., zip-lock) with silica gel or rice so that the phone is fully submerged.
• ⏳ Time: Leave for 12 to 24 hours. Change the adsorbent every 6 hours for better effect.
• 🔋 Check: Do not turn on the phone immediately after extraction - let it heat up to room temperature (10-15 minutes).

⚠️ Warning: If your phone has been in salt water (sea, sweat after exercise), don't use rice or salt, it will speed up the corrosion of your contacts. In this case, immediately rinse the speaker with distilled water (carefully, drip) and dry with silica gel.

Method 4: Disassembling the phone (for power users)

If water has been trapped deep inside the enclosure and previous methods have failed, a partial disassembly may be required, a method only suitable for those who are confident or have experience in repairing equipment.

What you need:

• 🔧 Plastic mediator (to open the case).
• 🧴 Isopropyl alcohol (90%+) — clean-up.
• 🧼 Cotton swabs and napkins without pile.
• 🔍 Lump or flashlight - to see oxidation.

Step-by-step:

1. Turn off the phone and remove all the cards.
2. Carefully tuck the back cover with a mediator (start with the corners). On Xiaomi models with adhesive body (such as Xiaomi 13), this can be difficult - don't put too much effort into it.
3. Disconnect the battery (required!) to avoid short circuit.
4. Check the speaker for moisture. If you see water, wet it with a napkin.
5. Soak the cotton swab in isopropyl alcohol and gently wipe the speaker and board contacts. The alcohol evaporates quickly and leaves no trace.
6. Leave the phone disassembled for 6-8 hours for a complete drying.

⚠️ Attention: disassembly of the phone is not warranty (if it is still valid), also the risk of damage to the plumes or display if you do not open the case neatly is very high.

Method 5: Software Diagnostics and Resetting

Sometimes the problem isn't the water itself, but the software failure caused by a short circuit. If the speaker doesn't work, but you're sure there's no moisture inside, try:

Steps for diagnosis:

• 🔍 Checking the sound in your headphones: plug in wired headphones. If you have sound, the problem is the dynamics. If you don't, maybe the audio system is damaged.
• 🔄 Resetting sound settings: go to Settings → Sound. → Additionally. → Resetting the sound settings.
• 📱 Test mode: enter the code ##4636## in the phone application, select Audio Test and check the speaker.
• 🔧 Hard reset (if nothing helps): back up your data and reset through Settings → The phone. → Resetting settings.

If the sound appeared after the reset, the problem was in the software. If not, most likely, the hardware components (speaker, audio codec or contacts) were damaged.

💡

If the speaker started working after the software reset, but after a while the problem returned, this is a sign of residual moisture.

What you can't do under any circumstances

Some popular tips can make things worse and cause permanent damage, and this is what you can't do if you get water in the Xiaomi speaker:

• 🔥 Dry with a hair dryer or on a battery: high temperatures deform the speaker membrane and melt the adhesive bases inside the case.
• 🧂 Use salt or sugar: These crystallize and can block the mechanisms of buttons or connectors.
• 💦 Shake phone: water can get deeper into case and damage motherboard.
• 🔌 Connecting a wet phone to charge: the risk of short circuit is extremely high.
• 🛠️ Independently disassemble the speaker: the membrane is thinner than paper - it is easy to tear.

Also avoid alcohol-containing liquids other than isopropyl alcohol (vodka, cologne, medical alcohol) that leave a film that prevents moisture from evaporating.

When do I contact the service center?

If after all the attempts, the Xiaomi speaker did not work, or there are additional symptoms, it is time to contact the professionals.

• 📵 The phone does not turn on or off after a few seconds after launch.
• 🔋 The battery is quickly discharged or the phone overheats.
• 🎵 There is a sound, but it is very distorted (cracking, whistling, interruptions).
• 💧 Under the screen or body visible drops or condensation.
• 🚨 Artifacts appeared on the screen (stripes, flickering).

The cost of repairing the speaker in Xiaomi depends on the model:

• Redmi Note 10/11: 1 200–1 800 ₽ (switch-over).
• POCO F3/F4: 1 500–2 200 ₽.
• Xiaomi 12/13: 2 000–3 500 ₽ (due to the complexity of disassembly).

The service center can also offer ultrasonic cleaning (effective in oxidizing contacts) or replacement of the audio module (if not only the speaker is damaged, but also the sound amplification circuit).

💡

If the phone is warranty, don't mention water, it automatically voids warranty obligations. Say the speaker "stopped working on its own."
