Troubleshooting My Philips Steam Iron is releasing smoke while heating up If your Philips Steam Iron is producing smoke, there can be several reasons. Please find out how we can help you. First few times the iron is used During production, some parts of your Philips Steam Iron have been slightly greased. As a result of this, your iron may produce some smoke when it is switched on for the first few times. Do not worry, this is normal. Water in the soleplate Sometimes, there might still be some remaining water in your iron’s soleplate after the last usage. This water will evaporate when your iron’s soleplate heats up, and that might look like smoke. This is normal and will stop after a short while.
