Display shows LE and the unit stops cooling; may beep repeatedly.

Important: The sealed refrigeration system contains refrigerant and must be serviced only by an EPA-certified technician (or equivalent in your country).

• 1. Basic checks: Ensure filters are clean and airflow is not restricted. Sometimes LE can be triggered by abnormal coil temperatures due to airflow issues.
• 2. Listen and feel: With the unit running in COOL (if it will run), listen for the compressor starting. If the compressor never starts or cycles rapidly, note this for the technician.
• 3. Visual inspection: Look for oily residue on copper tubing, around joints, or on the condenser/evaporator coils—this can indicate a refrigerant leak.
• 4. Do not attempt to recharge yourself: De'Longhi units are factory-sealed. Opening the system without proper tools and certification is unsafe and usually illegal.
• 5. Call a professional: Provide the model number, serial number, and the LE code to an authorized De'Longhi service center. They will check pressures, locate leaks, and repair or replace the sealed system components as needed.
