Control Lock Thank you for your question and I understand your concern. The "LOC" indicates the (Control Lock). This means the control panel has been locked and it will have to be unlocked before you can use the dryer. To unlock the control panel; press and release the Option and Select buttons at the same time.

The letters (LOC) indicates Controls are Locked. To avoid having someone accidentally start or stop the washer, press OPTIONS and SELECT at the same time until the Control (Control Lock) indicator is lighted. the controls, press OPTIONS and SELECT at the same time until the Control (Control Lock) indicator goes off.

https://www.google.com search gives several method to unlock the dryer, depending upon which model you have.

Example of one model dryer:

"To lock the controls between or during cycles, press and hold the Add Steam button for S seconds. LOC

will be displayed if you attempt to wake up a "between

cycle" locked unit and LOC will alternate with

cycle time remaining in a "during cycle" locked unit.

Repeat to unlock the controls when you are ready to operate the dryer. Use this feature to reduce the likelihood of accidental operation by children."

The control panel is locked. on the control panel, there will be either a "lock" button that you hold down for 3-5 seconds to unlock, or it will have "lock" in small letters with a line pointing to 2 of the option buttons. hold the 2 buttons it points to for 3-5 seconds and it will unlock. the control lock is a child safty feature that will not allow any the washer to work until it is unlocked. P.S. to put the control panel into the lock mode, is the same way as you unlock the control panel.

The control is locked to avoid having someone accidentally start or stop the dryer. Press and hold the Options and Select buttons for 10 seconds or until the "LOC" on the display is cleared. Locking the control is done the same way it is unlocked.

The control is locked. Press and hold the OPTIONS and SELECT button at the same time for 10 seconds or until "LOC" turns off. To lock the control, press and hold OPTIONS and SELECT until "LOC" is displayed. Unplug the machine for at least 30 minutes if pressing and holding the said buttons does not unlock the control to eliminate the possibility of an electronic glitch. The control may need to be replaced if unplugging the dryer still doesn't solve the problem.

Hold in lock button more than 10 secs,.

LOC means it thinks the control panel is locked.
This gives the ERR indication when you push the buttons.
To unlock it you need to hold down the Options and Select buttons together until it reacts.

Your child LOCk feature has been activated and will not let you do any further actions until you unLOCk it. Look in your users guide for unLOCking instructions.
