Delonghi Dehumidifier Error E8

⚡ Quick Answer: The E8 error code on your De’Longhi dehumidifier indicates a malfunction in the humidity sensor, primarily due to high refrigerant pressure detected... ✅ DIY Fixable

What Does Error E8 Mean?

The E8 error code on your De’Longhi dehumidifier indicates a malfunction in the humidity sensor, primarily due to high refrigerant pressure detected by the unit's protection system. This can lead to erratic display behavior and operational failure. Common symptoms include the unit shutting down, unusual noises near the compressor, and issues occurring during normal operation. Restricted airflow may exacerbate the problem, leading to heat build-up and triggering the E8 error.

Common Symptoms:

  • Unit displays E8 and shuts down
  • May be accompanied by unusual noises near compressor area
  • Occurs during operation rather than normal warnings

Possible Causes

  • High refrigerant pressure detected by sensor/protection system (medium)
  • Restricted airflow leading to heat build‑up (medium)

How to Fix Error E8

DIY Fix Check basic airflow and placement

  1. Unplug the dehumidifier from power.
  2. Ensure the rear and side grilles are not blocked by walls, curtains, or objects.
  3. Move the unit so there is at least ~20–30 cm clearance around intake and exhaust.
  4. Vacuum or gently clean dust from the air intake and outlet grilles.

Technician Only Inspect and service refrigeration/pressure components

  1. Check condenser coils for blockage or heavy dust and professionally clean if needed.
  2. Verify operation of the condenser fan to ensure it runs when the compressor is active.
  3. Measure refrigerant pressure with proper gauges to confirm overpressure conditions.
  4. Test high‑pressure sensor/switch and replace if faulty.
  5. Assess for refrigerant overcharge or contamination and repair sealed system if necessary.

Parts needed: condenser fan motor, pressure sensor/switch, refrigerant service (if needed)

🛑 When to Call a Pro:
  • If E8 returns after cleaning basic airflow paths
  • If unusual noises persist from compressor area
  • If pressure/sensor tests indicate overpressure or component failure
