My Mr Steam is 3 years old. When I turn the unit on, after heating up the unit spits out boiling hot water from the steam head! Help!

It is limescale. Basically your steamer takes water and boils it dry and turns it to steam. Any minerals like calcium in your water is left behind as rocks or flakes.

It should be descaled once every couple of years. You can do it fast with a product like CLR, or overnight with white vinegar. Fill it up and leave it, next day, turn it on and get it hot, but not boiling. Turn it off and leave it to cool. Empty and rinse 3 or 4 times.

Try draining out water and refilling it. sometimes there are deposits blocking

depends on how old it is, try to rinse it with a water and vinegar solution, this might help

To troubleshoot something like this.
1. make sure it's plugged and the outlet is working.
2. Is it getting hot? If not, either the heating element is burned out or not getting power.
3. If it is getting hot check the steam ports for calcium build up (run straight vinegar through it)

Tap water contains minerals/chemicals, whether it's from a well, or from a city source. When water is heated to steaming, these minerals, precipitate out of the water and form deposits. Use some vinegar. The mild acid will help loosen the deposits... and from now on use distilled water.

the hoses sometime kink when hot then get hard in the kink part once cooled down.. you may need to fin the area and warm it up to let the steam pass..

Seems silly... but is it plugged in to a live outlet? Does it have water?

It could be broken but it could also be jammed or clogged by some dirt or water. My first answer would be to get a new one. but if you dont want to throw it away you should take it to a recyling store.i know that is getting rid of it but it is not exactly because you still remember it.
