De'Longhi dehumidifier shows E8 and shuts down; may be accompanied by unusual noises from the compressor area.

Safety first: Unplug the unit immediately. High-pressure faults can be dangerous. Do not attempt to open the sealed system.

Step-by-step:

• 1. Check airflow: Ensure the rear and side grilles are not blocked by walls, curtains, or dust. Maintain at least 20–30 cm clearance.
• 2. Clean condenser coil: Remove the rear cover to access the warm condenser coil. Gently vacuum dust from the fins with a soft brush. Do not bend fins.
• 3. Verify fan operation: Power the unit and observe the condenser fan. It should start whenever the compressor runs. If the fan does not run or is very slow, replace the fan motor.
• 4. Monitor for recurrence: After cleaning and confirming fan operation, run the unit for 30–60 minutes. If E8 returns, the issue may be internal to the refrigeration circuit (overcharge, blockage, or faulty pressure sensor).
• 5. Professional service: High-pressure and refrigerant issues must be handled by a certified technician with proper gauges and tools.
