There are many causes of No Power on your Delonghi Dehumidifier...
No power at wall socket
Fuse in plug blown
On Off switch in off position
On Off switch defective
Water reservoir full - just a guess
And internal electrical fault of some sort
As for WHY then that's a more difficult question
Good Luck...
