Try cleaning the iron with vinegar. Here is a link to show you how.
Cleaning Clogged Steam Iron

My wife has one of these irons and she loved it. Now it steams for a while, and a red light starts blinking and it stops steaming. It can be turned back on and works for a while, then the same thing happens. I read that it needed descaled, so I bought OUST descaler and ran it through the iron, but it did not solve the problem. Any one have a solution to this problem, I would like to hear from you.

Have you checked the fuse?

take it back to were you got it from i think the regulator has just packed up

fill with water turn iron on max keep turning steam dial all the way to the right until you get to self clean hold iron horizontal and make sure you have a towel or something to catch water drips and debris coming out of iron let iron steam and spit water out until it stops on its own turn dial back to regular steam settings wipe residue off of the plate with a towel adjust temp settings back to normal

Iron not heating up sufficiently to produce steam. Threw it out!

perhaps the thermostat is sticking.as irons are cheap to replace i would try cleaning /soaking the tank to remove lime scale. or strip the iron down checking thermostat and conections.

these along with coffeemakers have a thermal fuse for safety the fuse looks like a cilinder with one flat side and the other side pointed with a wire protruding on both sides. it is located inline with the heating element under the cover "Appliance Parts" on the internet sells the part

The cost of repair is more than the cost of a new one. Therefore, trash it and buy a new one.

SELF CLEANINGIt is important to “Self Clean” the iron at least every two weeksto remove scale, calcium, etc. The harder the water, the more often the iron should be self cleaned.1. Set the variable steam control dial to any steam position.2. Fill the water tank up to the “MAX” level.3. Stand the iron on its heel. Plug the iron into the electrical outlet.4.Press the electronic temperature control button until you get the “MAX” temperature setting on the display panel and wait until the iron heats up and temperature setting light stops flashing.5. Turn the variable steam control dial all the way to the right to the self-cleaning position and hold the iron horizontally over the sink (Fig. 8).6. Boiling water and steam will now be ejected from the holes in the soleplate. The impurities and scale are washed away with it. 7. Move the iron back and forth as this happens.8. If there is any water left in the water tank after the iron stops steaming, just empty the remaining water in a sink following the instructions for emptying the iron. 9.Turn the variable steam control dial to the “0” position when the water tank is empty.10.Place the iron back upright on its heel to cool down before storing.
