About six hours ago my front-load washer was making odd clunking noises while performing a prewash cycle. Deduced it was the iPhone in a trouser pocket so I shut the machine off and waited until it deigned to allow the door to open. I found the phone in about three inches of soapy water and it seemed to still be working. I removed its case (fortunately not leather), rinsed its ports with cold fresh water and shook out as much water as wanted to come out. Next I tapped the bottom if the phone against my hand to clear our more moisture. Then it went under the warm dry airstream of the reverse cycle A/C for an hour. It seemed to be fine, so I made a backup over wifi with the iMazing app on my iMac before returning it to its spot near the A/C.
It has survived the experience perfectly fine. To be expected, it’s designed to survive being dunked in water up to a metre deep for up to 30 minutes.
