Delonghi dec 21 dehumidifier will not draw air and the green light will not come on thye water tray is empty and fitted corectly

Only thing I can tell you to do is to make sure that the evaporator in the back is ice and cold. If the evaporator is not cold the unit will never remove moisture from the air. And if that is the case you have a sealed system problem. The unit may have a leak so there is no gas in it. The compressor may not be working or the humidstat my not be working properly. So check those thigs out or if its under warrenty call for service.

You probably have a dirty heat exchanger. Write to me at [email protected] for free maintenance instructions on a smilar unit. Cheers.
