Did you accidentally pour water into the electrical vents? First, do not plug it in. Let it dry upside down in a warm spot for 24 hours. If you hear sizzling later, you’ve created an iron that hisses like a cat—unplug it and read the manual.
If you spilled water on your ironing board, just laugh it off. You’re now a water-to-iron professional in training. Even pros have puddles sometimes.
