What Does Error E5 Mean?

The Delonghi dehumidifier E5 error code indicates a malfunction related to high-pressure protection, typically linked to the humidity sensor or compressor issues. This can manifest as the unit stopping shortly after startup, the compressor attempting to start but cutting out, and no water being collected. The cause may be due to compressor overload, blocked condenser, or restricted airflow, leading to abnormal operating conditions.

Common Symptoms:

  • Unit stops operation shortly after startup with E5 displayed
  • Compressor tries to start (hums) then cuts out
  • No water collection despite attempt to run

Possible Causes

  • Compressor overload / high-pressure protection triggered (medium)
  • Blocked condenser / restricted airflow leading to high pressure (medium)

How to Fix Error E5

DIY Fix Basic checks and reset

  1. Unplug the unit and wait for a few minutes.
  2. Ensure the dehumidifier is placed in a well‑ventilated area with good airflow.
  3. Clean or vacuum dust from intake and condenser coils if accessible.
  4. Plug the unit back in and restart to see if E5 clears.

Technician Only Diagnose compressor and refrigerant system

  1. Verify compressor start behavior and current draw with appropriate instruments.
  2. Check condenser fan operation and airflow through coils.
  3. Inspect high‑pressure switch and related wiring.
  4. Assess refrigerant charge and measure system pressures if trained and certified.
  5. Replace faulty compressor start relay or high‑pressure switch as needed.

Parts needed: compressor start relay, high‑pressure switch, condenser fan or motor

🛑 When to Call a Pro:
  • If E5 persists after basic user‑level reset and cleaning
  • If there are unusual noises under load or signs of refrigerant leak
  • If internal electrical components are suspected faulty
