Model dx1700 won't heat up - Rowenta Effective DX1700 Iron with Auto Shut-off

adjust thermostat in lowest position

Have you try with lower heat setting?
It seems like it might be thermostat or thermal fuse that is not working properly.

There is a known issue with this happening for this model. The resolution is that you replace the switch.

My brand new DX1700 iron leaks. Why is it leaking. I had a Rowenta Professional for 17 years and it never leaked. What do I need to do.

The problem is with the iron's thermostat which controls the temperature of the iron

YOUR COIL MAY HAVE GONE ONT

inside the iron is a thermal switch that has failed to make contact. Dissassemble the iron and you will see a small white ceramic pin sticking up out of the heating chamber and on tip there is a small contact. Above it is another contact that makes the heating element work. Easiest way to fix is to put a small bead of glue on the housing to force the contacts together.

I just drop it a few times on the floor really hard a few times and then it gets hot again!!!

The thermal cutoff device blew and must be replaced. It acts like a fuse when the iron gets too hot. Thay are very
cheap and it would be well worth replacing. Hope this was helpful.

I hate to say this but I came here looking for solutions and it seems the solution is not to buy this Rowenta overpriced products.
