Dryer runs but display shows very short remaining time and clothes stay wet

Possible Causes
Dirty moisture sensor bars, Poor drum contact due to small load, Faulty moisture sensor wiring, Defective control moisture algorithm
How to Fix / Troubleshooting
Safety first: Turn off and unplug the dryer before any internal work.
- Clean sensor bars: Wipe the metal moisture sensor strips inside the drum with a cloth and white vinegar to remove residues.
- Adjust load size: Auto-dry works best with medium-sized loads. Very small loads may not contact the sensors enough; use a timed program for very small loads.
- Check wiring: If problem persists, access the sensor connections behind the front panel and ensure wires are intact and firmly connected.
- Control check: If cleaning and wiring are fine, the control board may misinterpret sensor signals and may need replacement.
