Part: Thermistor/temperature sensor

Child Lock/Control Lock Active

How to Identify: Display shows CL or CHILD LOCK; dryer controls unresponsive.

Part: Control panel Child Lock feature

Filter Not Installed/Filter Switch Error

How to Identify: FO or "Insert filter" appears; may occur if filter isn't seated correctly.

Part: Lint filter detection switch

Humidity Sensor Error

How to Identify: HS code appears; loads may take long with incorrect dryness detection.

Common Issues Reported by Users

  • Blocked or restricted venting system
  • Faulty moisture sensor
  • Malfunctioning control board

User Suggested Solutions

  1. Inspect and clean the venting system. Disconnect the dryer from the power source. Remove the vent hose from the back of the dryer. Clean out any lint or debris from the vent hose and the vent duct leading outside. Reattach the hose and test the dryer again.

  2. Check and clean the moisture sensor. Locate the moisture sensor inside the dryer drum (usually two metal strips). Wipe the sensor with a soft cloth and a mild detergent to remove any residue. Test the dryer to see if the error persists.

  3. Test the control board for faults. Unplug the dryer and access the control board. Check for any visible damage or burnt components. If faulty, replace the control board with a new one.
