There could be multiple reasons why the steam feature on your Soleil iron isn't working. One possible cause is a clogged steam vent. Follow the steps mentioned below to unclog it: Fill the iron's reservoir with a mixture of one part white vinegar and two parts water. Turn on the iron and let it heat up. Hold the iron soleplate-side down and press the steam button until steam flows freely from the bottom. Pour out any leftover liquid and rinse the iron with distilled water. This method should help resolve blockages and improve the iron's steaming functionality.
