Delonghi Portable AC Error Codes (A Complete List + Explanations)

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.

  1. For the past few nights I keep getting a HL error code. I empty the tank each time but it keeps doing it. I’ve had it for like 4 1/2 months now. Please help

  2. 2 years ago our Pac we112 eco posted an ‘F1’ error.
    After having an regular ordeal trying to find a service center and waiting forever for it to be returned it was ‘fixed’
    Last year we did not need to use much, perhaps 5 times as the summer wasn’t too hot. We drained it and properly stored it.
    Today I hooked it up and once again it has an ‘F1’ error.
    Honestly before I bother taking to a service center a have it gone the rest of the summer making it totally worthless to own such a thing, we’ll simply let it run until it dies and never buying another product from DeLonghi again.

  3. Hello,

    My DeLonghi Pinguino 4-1 is having issues

    The AC/Dehumidifier/Fan work fine in my opinion but the heat isn’t working. It’s just giving a blinking sun issue.

    Any help would be appreciated

    • Mine had the same issue. I drained the water by unplugging the rubber plug on the back near the bottom. Once I did that, all the other functions worked except the heater. I just blinks. So I set it to its highest temp and left it. After 3-5 mins it clicked, then a few more minutes, and the heater finally kicked on. Hope this helps.
