Olimpia Splendid Humidity Sensor Calibration / Range Error

Dehumidifier shows F2 and will not run in normal mode.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

RH sensor reading outside 0–100% range, Sensor contaminated by dust or chemicals, Failed humidity sensor module, Faulty main PCB ADC circuit

Steps:

Clean sensor area: With power off, access the humidity sensor and gently blow away dust. Avoid touching the sensing element directly.
Check environment: Ensure the unit is not exposed to corrosive vapors (e.g., chlorine, solvents) that can damage the sensor.
Sensor replacement: If F2 persists, replace the humidity sensor assembly with a compatible Olimpia Splendid part.
Board check: If a new sensor does not resolve F2, the main PCB may require replacement.
