If your Face ID isn’t working after water exposure, turn off your iPhone right away and let it dry completely before using it again.
A few days ago, one of my YouTube subscribers messaged me saying their Face ID not working after water damage on their iPhone. I’ve seen this happen often, especially when users drop their iPhones in water or use them in the rain, thinking they’re “waterproof.” So, I decided to write this quick and practical guide on how to fix Face ID after water damage based on my own experience and verified Apple documentation.
If you’ve noticed your Face ID not working after water, this post will help you understand what’s happening and what you can safely do next.

Why Face ID Stops Working After Water Damage
Face ID uses advanced infrared sensors and cameras hidden under your screen. Even a small amount of moisture can interfere with these sensitive components.
Here’s what usually happens:
- Water or humidity gets inside and causes corrosion on the Face ID sensors.
- Power leakage or short-circuiting prevents the sensor from reading your face.
- The phone may work fine overall, but the Face ID module fails silently.
So if your phone got wet, even for a few seconds, that could be enough to cause the problem.
Is Face ID Damage Covered Under Warranty?
Apple’s standard one-year warranty does not cover water damage.
Even though newer iPhones have a water-resistant rating (like IP68), Apple clearly states it’s not a permanent condition and can reduce over time.
If your iPhone has visible moisture or internal corrosion, the repair will likely be treated as out-of-warranty. Apple technicians can confirm it using internal liquid contact indicators.
What to Do if Face ID Is Not Working After Water
Before you panic or start pressing random buttons, here’s what you should actually do:
- Turn off your iPhone immediately.
Keeping it on can cause short circuits if there’s still moisture inside. - Do not charge it or use a hair dryer.
Heat can push water deeper inside or damage nearby chips. - Let it dry naturally.
Place it in a cool, dry area for 24–48 hours. Avoid rice—it doesn’t really help much. If available, use silica gel packs. - Restart your iPhone after drying.
- Hold the power button until you see “slide to power off.”
- Swipe to turn it off, wait a few seconds, then turn it on again.
- Sometimes, a software glitch might temporarily disable Face ID, and a restart resets it.
- Check Face ID settings.
Go to Settings → Face ID & Passcode and try resetting Face ID.
If it says “Face ID not available,” there’s likely hardware damage. - Visit an Apple-authorized service center.
Face ID is linked to your iPhone’s logic board, so even Apple technicians can’t just replace the sensor without special calibration tools. Independent repair shops may not fix this securely.
Should You Try DIY Fixes?
I know it’s tempting to follow YouTube tutorials, but be careful.
Face ID parts are paired with your phone’s motherboard for security. Replacing them yourself or through an unverified shop can permanently disable Face ID.
If your Face ID not working after water and basic drying or restart doesn’t help, go to Apple Support or an authorized repair center. They have the right tools to safely diagnose and replace the affected modules.
Quick Tips to Prevent Future Damage
- Avoid unlocking your phone with wet hands.
- Don’t take underwater photos without a waterproof case.
- If you use your phone in rain or near water, wipe it dry immediately.
- Always use original Apple parts if repair is needed.
FAQs
Can Face ID recover automatically after water damage?
Sometimes, yes. If the moisture was minor and dried quickly, Face ID may start working again after 24–48 hours. But in most cases, hardware corrosion makes it permanent.
How much does it cost to repair Face ID at Apple?
It depends on your model. Apple may charge anywhere between ₹20,000–₹35,000 in India if it’s not under warranty.
Can Apple replace only the Face ID sensor?
Not directly. Since Face ID is paired with the motherboard for security, Apple usually replaces the entire display or logic board module if needed.
Final Thoughts
If your iPhone Face ID stopped working after water, act fast. Power off your phone, let it dry, and avoid trying random fixes. In my experience, quick action can sometimes save the sensor. But if Face ID still doesn’t respond after drying, let Apple handle the repair.
