The dehumidifier is 7 years old. It runs, but I it won't pull any water out. It is humid enough, so it should work. I have cleaned the filter and I can't see anything that does not look normal to me.

Don, unless your dehumidifier is a Low temperature model, that very well may be the problem.
The air temp in a basement at floor level is colder than that chest level. Dehumidifiers don't work well at temperatures at 40 degrees F or less. Raising the unit up off the floor on to a sturdy table, counter top, etc, that is strong enough to handle it's weight, plus a full tank of water, will generally solve the problem. The higher up you can safely put it, the better. Also, lower the humidity extraction level to 35%. As 50% is just not low enough in a basement application.

Hope this helps you to solve the problem.

There are 4 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. Also, keep in mind, basements stay moister longer than upper rooms.

1. The humidity extraction level is set to HIGH. Lower it to 32-35% and disable the auto mode.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

derkfarm - It may simply be a case of the humidity extraction level being set to high and/or the air intake filter needs to be removed and cleaned.

Solution: Lower the humidity extraction level to 32 - 35% and clean the air filter.

If the unit is in a basement, the ambient air temperature at floor level is colder than at chest level. Dehumidifiers don't work well at temperatures between 40 - 60 degrees F.

Solution: Set the unit up off the floor on a sturdy table, cabinet, counter top, etc. It must be sturdy enough to handle the weight of the unit, plus a full tank of water and the vibration, while in operation.

Any or all the simple solutions above may solve the problem. But, we won't know, until you try them.

Please let me know if it helped or didn't solve the problem. Thanks.

Chris, it may be that the humidity extraction level (%) may be set to high. Lower it to 32 - 35%. Also, a dirty or clogged air intake filter will also cause the problem.

In addition:

Not enough clear air space around the unit. You must maintain a minimum of 12" clear air space around the entire unit.

If it's a basement application - The air temperature at floor level is colder, than at chest height. Raising the unit up onto a sturdy table or cabinet that can handle the weight of the unit and a full bucket of water, normally resolves that problem.

On the more serious side ... The unit is 7 years old and the compressor may need to be recharged with R14 refrigerant. Or the humidity sensor may have failed. In either case, since the unit is 7 years old, it would probably cost you as much to repair, as it would to replace it. That's a decision you'll have to make.

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

You may have the humidity/moisture level set to high. Try lowering it to 35%. Or if you don't have a LED Screen on your unit, turn it to maximum.

In addition, most dehumidifiers don't work well if the air temperature is between 40 & 60 degrees F. Keep in mind, the temperature at floor level in a basement is colder that the air temperature at chest high level. Raising the unit up, off the floor on something sturdy enough to handle the weight (with a full tank of water) and the vibration, may help.

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

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

If you brief description of the problem is correct, you need to turn the humidity/moisture extraction percentage down to 35% and check and clean the air intake filter. Maintain a minimum of one foot air space clearance around the entire dehumidifier and be sure that all exterior doors and windows are closed. DO NOT attempt to remove and clean the filter with the unit ON and plugged in to the wall outlet.

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

Possibly lost refrigerant from system- check warm air is coming out of machine. Otherwise it could be dirty filters, and not getting enough air over evaporating coil. Other than this, replacing parts is usually more expensive than buying a new dehumidifier :(
