I used most of this guide through step 10 after dropping this in water; I didn't take out the power cord. I left the partially disassembled straightener in a container with desiccant overnight to remove the moisture. There was some corrosion on the switch that prevented the device from turning off that I cleaned up with isopropyl alcohol . I confirmed the switch behavior before and after cleaning with a multimeter to check continuity. On my device, the contact closest to the heating element was supposed to be disconnected from the other two contacts when off; when on, they were all showing contact. Before cleaning, there was continuity between all contacts. Thanks for the guide.
