I am having the same problem with my good Kenmore- the button is pushed down and won't pop up.  Wonder if we can take the cover off and resit the button?  As i bought it on sale for $40 and they charge $30 to CARRY it in to the repair shop to have them look at it - in my case it may be cheaper to buy a new one.  I know Rowenta's can be pricey so try calling appliance repair shops and checking prices/ labor /parts.
