20 Most Recent DeLonghi Stiromeglio Compact PRO 300 Iron Questions & Answers

The Delonghi Pro300 has two thermostats that contact the boiler. One is a low temperature thermostat that allows the boiler to heat up to 145 degrees (F). The other turns off the boiler when the temperature reaches 180 degrees. It sounds like your low temperature thermostat has failed. The part can be ordered on line. You need to have good basic mechanical skills and the proper sized star screwdriver to replace it.

You have a short in the wiring inside of the iron. It will not work until you get the short fixed.

Electric Iron not Heating Up or not Working Right

I would first try with household vinegar (empty as much water as possible) and if that doesn't work to free the valve, then something more aggressive containing acid like any of the Lime Away type of lime/rust removers. If it is still stuck, you may have to bet the iron hot to make the acid more effective. If using other than vinegar, I wouldn't advise allowing anyone to breath the vapors; do this in a utility room or basement.

That trigger probably acts on a needle valve that controls the flow of water to the point at which it is turned to steam and it may simply be too contaminated with lime buildup to slip back into the valve body.
