iPhone 11 Pro through washer still works. Next step?

Then it doesn’t still work if it won’t charge. Your phone is toast. Apple’s formal support can be reached several ways:

• Click on “Support” at the top of this page
• Go to Contact Official Apple Support

Note that both of the above have options to receive a callback or chat

• Install the Apple Support app on your iPhone or iPad - you can contact support directly from the app, and the tech will have (with your permission) access to diagnostic data on your phone
• Call Apple Support; the phone numbers are in this link→Contact Apple for support and service - Apple Support
• Make a Genius Bar appointment at an Apple Store→Genius Bar Reservation and Apple Support Options - Apple
• Find an Apple store or Apple partner service provider→Find Locations

You already past that point. You should have turned it off immediately and waited several days for it to try out before attempting to use it. But water damage is progressive; it will develop other problems shortly.

I can charge it on a wireless pad. And all functions phone music video still work. Ideas would be welcome for a phone drying out process.
