The unit still makes a running noise but seems to collect no water. this unit is about 4 years old but stopped collecting water about 2 years after purchase

Have you emptied the water out of it?

Hi,
There are many reasons why a dehumidifier willnot work or collect water.

You may still have some packaging materials left inside the unit. The plastic pan doesn't stay in side the bucket. It's used as a drain pan on the outside. Also, be sure the air intake filter is in place, is clean and there are no packaging materials behind it.

To extract more humidity, after checking all the things mentioned above. Lower the extraction level to 32 to 35%. Lower percentages means extraction of more humidity. (i.e.200% -35% = 5% drop in humidity).

Hope this helps you troubleshoot and solve the problem. Please let me know. Thanks.

Depends on he conditions of the water. These units are relatively inexpensive and typically do not justify the expense of repair. I'ld donate it to an air conditioning school and buy another one.

I hope someone answers this because I'm having the same problem. Mine is about 4 years old. I thought it was my filthy filter but cleaning didn't change the problem.

the evaporater coils rot out and the freon leaks out. thats about all the longer these newer ones last now.

It appears that these units have a history of defectiveness. I bought one in late 2010 and it pooped early 2012. If the model is still made, buy a new one, return the defective one in the new unit's packing materials for a refund. Or keep the second (new) unit as a back-up, because the new (first) one may just fail again a short while later.

My unit does not collect water any more. It was fine until I lent it to my brother in law and it was returned damaged. Do you know how to fix this
