Delonghi portable air conditioner smell bad
- Dust filter and (where applicable) electrostatic filter clogged.
- Clean the filters (as described above).
Delonghi portable air conditioner does not run for about 3 minutes after it has been restarted
Possible causes: the unit’s internal compressor safety gadget prevents the AC from being restarted immediately after it has been turned off and three minutes have to elapse since it was turned off before it can restart.
Wait! As mentioned, this delay cannot be canceled for it to operate normally.
Delonghi portable air conditioner keeps shutting off
This means the compressor keeps stopping.

- Clean the filter (if clogged).
- Always check to ensure empty tank symbol is not showing on the AC’s display. Drain the unit, if shown.
Delonghi portable air conditioner error codes
The appliance is equipped with a self-diagnosis system to help you identify a couple of malfunctions and the good news is that the system shows a variety of error messages on the display to point you in the right direction.
Here are the most common De’longhi error codes and practical troubleshooting ideas:
Delonghi portable air conditioner error code HL
Meaning: HL means high level and it simply indicates that the internal tray is full.
Recommended troubleshooting: Empty the unit’s internal safety tank.
Follow these steps to empty the tank:
Step 1: Pull out the tank
The water tank -installed at the bottom- is removed by simply inserting your hand thr0ugh the door just above the word PULL (see figure 13 below) and pulling it out as far as possible.
Step 2: Detach the drain hose
Detach the tank’s drain hose (located on the left of your tank as shown in figure 40-41) and position the end in a jug/bottle to act as a recipient.
Step 3: Drain the tank
First, replace the sp0ut cap(G) with the drain h0se + cap(U).
Now remove the cap then run off the water until completely empty.
Replace the cap.
IMPORTANT NOTE: the tank can contain up to 2 liters of water.
Delonghi air conditioner error codes – meaning and how to fix them
Delonghi air conditioner error code LT
Meaning: Low Temperature (so the integrated frost protection device is trying to prevent excessive formation of frost)
Recommended troubleshooting: No action needed-the appliance automatically starts up again when defrosting is complete.
Delonghi air conditioner error code CF
Meaning: Change filter
Recommended troubleshooting: When this error is displayed, you need to change the water filter.
Follow the process below to change the filter:
- Buy a replacement filter.
- Empty the tank and the internal tray as earlier described.
- Turn off the AC and un plug it from mains.
Step 1: Lay it on the back
Lay the AC on its back (see figure 17).
To avoid scratches/damage, the appliance should rest on a towel/piece of cardboard.
Step 2: Unscrew the filter cover
The filter cover is removed by first unscrewing the 4 screws (see fig. 17 again).
Step 3: Remove the filter
You can remove the filter delicately- loosen the 2 ties while ensuring the 2 hoses connecting your filter won’t slip inside the AC.
Step 4: Install new filter
Fit your new filter- just follow the above procedure in reverse (see figure 16/15).
- Water can leak out as you replace the limescale filter. To avoid this, perform the procedure in an ideal location.
- Wait an hour (at least) after replacing your filter before starting the appliance again.
- When the filter is replaced, turn off the alarm by pressing the “ON/STAND-BY” button (15) for about 10 seconds. The unit produces a beep.
Delonghi air conditioner error code F1
Meaning: Failure 1
Recommended troubleshooting: The appliance normally continues to function properly in air-air mode when the F1 alarm/error code is shown. But you can reset the alarm by unplugging the AC then plugging it in again.
Delonghi air conditioner error code PF
Meaning: Probe Failure (so the sensor is damaged or probe is damaged)
Recommended troubleshooting: If this error is displayed, talk to your local authorized Delonghi service centre.
How to reset Delonghi portable air conditioner errors (there’s no Delonghi portable air conditioner reset button!)
Sometimes the only way to get rid of an error code is to hard reboot your Delonghi air conditioner.
To do this:
- Turn off the AC or unplug it.
- Allow it to for about five minutes.
- Plug it back in.
You can now try to use it- the unit resets errors when the control board loses power for a few minutes.
As with other electrical appliances, you should use caution and common sense when applying the above Delonghi portable air conditioner troubleshooting instructions on your unit.
