Used maybe 6x over the 1st year I've owned it, pulled it out to help warm my daughters room and it squeals like mad as soon as you turn it on.
After a few discussions with repair techs, advised its most likely the left and right motors which need replacement, surprise surprise the parts can NOT be bought anywhere, the only option is to ship for service and pay more for shipping than it's worth.

Shame on Delonghi for making such a poor quality product and not making parts readily available.
