Dehumidifier display shows HI and runs continuously

Safety: Unplug before accessing internal components.

Steps:

• Verify environment: Use a separate hygrometer to confirm actual room humidity. If humidity is indeed very high, allow the unit to run; HI is informational.
• Check for condensation: If the unit is in a very damp area, condensation can form on the humidity sensor. Turn off the unit and allow it to dry, or move it to a slightly drier area.
• Inspect sensor: If HI is displayed even in a dry room, remove the front grille and locate the humidity sensor. Ensure it is clean, dry, and properly connected.
• Replace sensor: If the sensor is connected but always reads HI, replace the humidity sensor assembly with a Sunbeam-compatible part.
