The drum may be overloaded, or the hot and cold water inlet hoses may be reversed.
- LG · Laundry · DLEX4000B · reviewed answer
Why are some clothes still damp after Sensor Dry?
The load may be too large or too small for the sensor to read correctly. Very large bulky items can also dry unevenly. Use Time Dry for very small loads, pause and rearrange bulky items if needed, or finish damp items with Time Dry after emptying the lint trap.
- LG · Laundry · DLEX4000B · reviewed answer
Why does my dryer start by itself every few minutes?
This is how the Wrinkle Care feature works. The dryer runs briefly every few minutes for up to 3 hours after the cycle finishes to help prevent wrinkles if you do not unload the dryer right away.
- LG · Laundry · DLEX4000B · reviewed answer
Why does my dryer take a different amount of time for similar loads?
Drying time can vary based on load size, fabric type, how wet the clothes are, and the condition of the lint filter. An unbalanced washer load can also leave clothes wetter and increase drying time.
- LG · Laundry · DLEX4000B · reviewed answer
Why does my dryer take so long to dry clothes?
Poor airflow can increase drying time. A lint filter that is full of lint or clogged with fabric softener sheet residue can reduce airflow and make drying take much longer. The manual also refers you to the troubleshooting charts for more tips.
- LG · Laundry · WM4000HBA · reviewed answer
Why is there so little water in my washer? How can it clean the clothes?
That is normal for an HE (High-Efficiency) washer. It uses a minimum amount of water and energy, and the low water level makes the detergent more concentrated for effective cleaning.
- LG · Laundry · DLEX4000B · reviewed answer
Why should I clean the lint filter before every load?
A clogged lint filter increases drying time. The filter should be cleaned and reinstalled firmly before starting the dryer.
- LG · Laundry · WM4000HBA · reviewed answer
Why should I flush the water hoses before using the washer?
Flushing removes foreign substances like dirt, sand, or sawdust. The manual says these can damage the washer inlets and cause leakage.
Error codes
- LG · Laundry · DLEX4000B · error code
d80: LG DLEX4000B d80 error code
