    Hl code in a delongui portable air cond…I drained already an still the same

    1. Hi,
      The HL code on a Delonghi portable air conditioner indicates that the internal tray is full. This means that the water that has condensed from the air has not been able to drain properly.

      If you have already drained the tray and the HL code is still appearing, it is possible that there is a problem with the drain hose or the float switch. The drain hose may be clogged or kinked, preventing the water from draining properly. The float switch may be faulty, preventing it from signaling the unit to stop running when the tray is full.
