What F37 means

F37 appears on LG dishwashers with an Auto Open Door feature. It means that feature is not working: at the end of a cycle the door is supposed to open slightly to let steam out and help the dishes dry, and the control has found that it does not. The dishwasher may still wash normally. Codes can differ by model. Something near the door, like a cabinet panel or a mat, can get in the way, which is why we start with what is around the door.

Common causes of F37

Object or cabinet panel interfering with the door
Door opener mechanism
Control output to the opener

✓ One safe check you can try

1. Look at the area in front of and beside the door for anything that could block it, such as a mat or a cabinet panel. 2. Clear it and close the door. 3. Run a short cycle and watch whether the door opens at the end. 4. Wipe any steam off the door edge. 5. If F37 returns, call us.

! Why to stop there

If nothing is in the way, the opener or its control is the next thing to test.
We check how the door moves and whether the opener gets a command.
We run a cycle and watch the door open at the end before we finish.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F37F37 questions

Does F37 stop the dishwasher from washing?

Usually not. The wash can run normally while the Auto Open Door feature does not. Dishes may come out wetter because steam stays in. Check the area around the door, and if the code returns, we test the opener.

What can interfere with the door?

Anything close to the front, like a cabinet panel, a mat or a towel. Clear the area and test again before you decide the feature is broken.

Should I open the door by hand?

Yes, you can open it manually after the cycle to let steam out. Do not force the door if it feels stuck. Call us if it will not move freely.
