De’Longhi S.p.A. is an Italy-based small appliances manufacturer based in Treviso, Italy. Founded in 1902 the company dealt in industrial parts manufacturing. It was not until 1950 that the company started to take on portable heaters and air conditioners. Expanded their business to the small domestic appliance category that was allowed by ironing, cleaning, and other segments.
Today, the company is widely known for its coffee machines, and portable air conditioners. Apart from its system, the company is known for its design statements – bringing you the best of both worlds. However, it was not until 2000 that the company entered the commercial HVACR market. However, it’s their portable air conditioner that still takes the lead.
Designed to bring a smart cooling solution to your rooms the portable ac has come a long way. That being said, there are times when you might face issues and errors bringing the system to a halt. Start by noting down the error code, and match it using the list below. Once you have the error code you can easily work your way to the fix. To help you out we have listed down some of the most common error codes for Delonghi portable air conditioners.

Troubleshooting
Problem: The air conditioner does not come on
Cause:
- there is no current
- it is not plugged into the mains
- the internal safety device has tripped
Solution:
- wait
- plug into the mains
- call the Service Centre
Problem: The air conditioner works for a short time only
Cause:
- there are bends or kinks in the air exhaust hose
- something is preventing the air from being discharged
Solution:
- position the air hose correctly, keeping it as short and free of curves as possible to avoid bottlenecks.
- check and remove any obstacles obstructing air discharge
Problem: The air conditioner works, but does not cool the room
Cause:
- windows, doors and/or curtains open
- there are heat sources in the room (oven, hairdryer, etc)
- the air exhaust hose is detached from the appliance
- dust filters clogged
Solution:
- close doors, windows and curtains, bearing in mind the “tips for correct use” given above
- eliminate the heat sources
- fit the air exhaust hose in the housing at the back of the appliance
- clean or replace the filters as described above
Problem: During operation, there is an unpleasant smell in the room
Cause: dust filter and (when present) electrostatic filter clogged
Solution: clean the filters as described above
Problem: The air conditioner does not operate for about three minutes after restarting it
Cause: the internal compressor safety device prevents the appliance from being restarted until three minutes have elapsed since it was last turned off.
Solution: wait. This delay is part of normal operation.
Problem: The symbol and one of the following messages LT / HL/Cf/PF / FI appears on the appliance display:
Cause: The appliance has a self diagnosis system to identify a number of malfunctions.
Solution: See the SELF-DIAGNOSIS chapter.
“CF” is displayed when the limescale filter needs replacing. The efficacy of the filter depends on water hardness. It should, however, be replaced every five years.
If the remote control unit is replaced or discarded, the batteries must be removed and disposed of in accordance with current legislation as they are harmful to the environment. Do not mix old and new batteries. Do not mix alka line, standard (carbon-zinc) or rechargeable (nickel-cadmium) batteries. Do not dispose of batteries in fire. Batteries may explode or leak.

Hi
I have a Logic aircon
The Lt sign comes on, aircon pump goes off.
I know it is Frost protection
But it does not restart by itself
I have to switch it off and on again to restart the compressor
Any suggestions
Regards
Eric
I have same problem. Did you figure out how to fix it?
Love the fact that I can look up error codes, had the HL error code and found the answer to my problem here. Thank you
I have an error code PF probe failure….what can I do to fix this?
There is a small black plug located at the back of the unit at the very bottom. Put a flat cookie sheet with short sides under the plug and pull it out. Water will come out and the caution sign will go off. The unit should now come on.
Rich, Thank you so much! I had the same trouble. The DeLonghi manual didn’t address the error code I had, but I followed your instructions and WOW! I have COLD AIR again!!!
I have the same problem. I remove the plug and no water comes out. The error code keeps on flashing. Is there a reset sequence?
Regards

JOhan, it’s usually necessary to tilt the machine in order for water to drain.
