If you have an LG washing machine which is indicating error code CL here’s what it means. CL stands for child lock. It may just have been accidentally activated.
How to turn off child lock
Try holding down the temperature and eco/rapid options together to turn off child lock. Many washing machines have a child lock system in place, sometimes it can be as basic as a lockable door.
But many modern washing machines are controlled by software, and the child lock can be activated and deactivated by pressing certain option buttons. Check your instruction book for more details.
If you don’t have your instruction manual you can probably download it from one of my links here – Appliance manuals
