Your model Delonghi Dehumidifier has been retired. Therefore, no online manual is available. However, if you contact Delonghi Customer Support (1-800-322-3848), they can furnish one and answer the question about the PF error code at the same time.

Thanks for choosing FixYa.

Phil, it may simply be a case that you have the humidity extraction level set to high. Try lowering it to 32 - 35%. If your unit is not equipped with an LED Screen, set the manual control to Maximum.

Also, remove and check the air intake filter, to see if it needs cleaning. And maintain at least a minimum of 12 - 18" of clear air space around the entire unit, while in operation.

Hope this helped you. Please let me know. Thanks.

Unfortunately, Delonghi, for whatever reason, does not post the Owner's Manuals for their Dehumidifiers online. However, if you call Delonghi Customer Support 800-322-3848 they can furnish one to you. Probably by email attachment.

Hope this helped you. Please let me know. Thanks.

Sorry to read about your problem, I hope this helps you out.

Their has to be a model difference issue . I have checked the Manuel and have put a copy of the section, for modes. and their is no heat only mode.

Your unit uses heat anyway, so i really do not know how, heat only would help you. I would say to look at the sticker on your friends model, and see if the numbers are exact.

Default Setting:

When the unit is first connected to a power supply, the electronic circuit board will automatically default to the following factory settings;
Mode: Dehumidifier Humidity Set Air Value:60% RH Fan Speed: = Low

NOTE: In the event of a power failure or the unit is switched 'Off', the most recent settings are retained and restored once the power is switched "On"/resumed.
IMPORTANT NOTE: Depending on the ambient humidity conditions, when power is restored or switched 'On' the dehumidifier may not start automatically under the factory or custom (see page 7) default setting. This is an indica- tion that the ambient RH% level of the surrounding envi- ronment is lower than the current default setting and it may be necessary to select a lower set RH% value.
DRY MODE SELECTION: 1. The unit does not have to be switched on (opera- tional) to select/set a program. All programs can be selected with the unit in the "off" position.
2. Press the MODE button until the Dry symbol is shown in the mode area of the display. Note: Each time the MODE button is pressed, the setting will alternate between DRY (dehumidifier) and FAN (only) mode.

3. Press the or cursor buttons to select the desired RH% operating value. To select CONTINUOUS operation,pressthe buttonuntilthesymbol"--" appears in the SET AIR display. During CONTINUOUS mode operation, the humidistat (control) will be by-passed and the compressor will operate non-stop regardless of humidity conditions.
FAN SPEED SELECTION:

4. Press the fan symbol on the keypad. Each time the button is pressed, the mode selection will alternate between "High Fan" and "Low Fan" speed options. The fan speed you select will appear in the LED display; either a 4 blade fan symbol for 'high fan' or a 3 blade fan symbol for 'low fan' will be shown in the display area.

5. When all settings are complete, press the I/O button to start the selected operation (MODE) and the blue opera- tion light will illuminate.

FAN ONLY MODE SELECTION:
1. Press the MODE button until the fan blade symbol is shown in the mode area of the display. 2. Press the "Fan" symbol on the keypad. Each time the button is pressed, the mode selection will alternate between "High Fan" and "Low Fan" speed options.
3. When all settings are complete, press the on/off button to start fan mode operation and the blue operation light will illuminate.

I have the delonghi DEN500P and the unit runs but does not condense any moisture? The appropriate buttons have been set to bring the unit humidity setting well below humidity in room

i would like to know if the =unit turns off when it get to the tempature that you put it at

I went back and rechecked. If the fan mode is selected, you can only set the fan at one of the three speeds. If you leave it in the fan mode, the dehumidifier will not come on.

Once the fan speed is selected, it will run at that speed in the dehumidifier mode. The fan will keep running, even when the dehumidifier (compressor) shuts down.

The only way to get it to turn off is to use the clock setting, which either selects how long it stands-by before starting , or how long it will run before going back to stand-by. DeLonghi calls it "stand-by," we would call it "off." DeLonghi calls unplugged "off."

I've never turned mine to stand-by, because it will never get my entire house down to 30% humidity (I have it where my air handler returns air to the basement). I live in the greater DC Metro area, where 75% humidity is considered extremely dry.

Apparently the normal mode of operation is fan on unless awaiting a clock start, or encountering a clock shut-down; either condition puts it into the "stand-by" mode.

don't know if you ever found your manual but if still looking go to..

If you have the fan icon selected, it is supposed to run continuously. If you use the mode button (not the fan button) to change to relative humidity (the water drop icon), the fan should only run with the dehumidifier.
