LG Dishwasher Error Code F37 — Auto Open Door Error
What this means
The F37 error code indicates the Auto Open Door feature failed to operate. Some LG dishwasher models automatically crack the door open at the end of a cycle to improve drying through natural air circulation. If the door mechanism is blocked by an object, the hinge is damaged, or the motor that opens the door has failed, F37 will appear.

2 stepsClear obstructions
Make sure nothing is blocking the dishwasher door from opening, such as a kitchen chair, rug, or cabinet handle in the door's path.
Power-cycle the dishwasher
Turn off and unplug for 1 minute, then restore power and run a cycle to see if the auto open works.
When to call a professional
If the auto door motor or mechanism has failed, professional service is needed to replace the auto door assembly.
