Steam Button Sticks in

Lime scale is the enemy and especially in hard water areas it can cause things to stop working.
Using a descaler might work though often a stripdown and manual cleaning is needed.

Hope this helps, if you require any further assistance please contact me.

I've looked up parts for this iron. Sorry to say the steam button is not listed. The button may be able to be repaired at a small apliance repair center, but I do not know what the cost would.

I think lime and calcification are the culprit. Use some "CLR" at Home depot, can decalcify the build up on your irons pressure cap.

I have the Rowenta Steam Station. Love it!

Chemicals and minerals in the water have probably clogged the vents. Empty the water. Pour 1/2 cup WHITE vinegar into the reservoir. Turn on your iron and let it heat. Then press the steam generator button several times until the vinegar is gone. Unplug the iron. As it is cooling, take acotton swab and gently wipe the surface of the vents. You can probe GENTLY with the swab, but don't push it into the vent or the cotton head may get stuck.
As you're pressing the steam button, keep the iron in the ironing position, not standing. If the vinegar just will not come out of the vents, use a wooden toothpick to loosen the build up.
This always works well for me and I hope it does for you.
If so, please come back to Fixya and rate my advice!

Found this on another site and just tried it. Put 50/50 water and vinegar in the tank and leave it to go through on the constant steam. Give it about 5 minutes then try the button. Mine gave an extra spurt of steam at this point but still continued giving steam out all the time. I refilled with the water vinegar mix and just kept pressing the steam button and letting it go through. Eventually it fixed it and the constant steam stopped. Something to do with a piece of limescale blocking the solenoid but that's all Greek to me! Hope this helps. Kind regards.

I had the same problem. I found the trigger button at SmallAppliances.com. You'll have to pry off the rubber grip, and unscrew one or two screws on the handle, bu the trigger inserts neatly into the space. Screw it back together, snap on the rubber grip and it will work like new. Below is the part number & price.

Watch out, the next thing that will go is the on/off switch. Once it starts getting difficult to turn the unit on or off, just plug and unplug it until you get the new part, or you will be stuck one day and need the iron and go to turn it on and it wont start.

The part is $20, and the same site has it available.
