LG Dishwasher · Error code F37
What F37 Means

- Door does not pop open automatically

3
Broken plastic linkage
Push arm cracked from impact or age.
4
Loose harness to vent motor
Connector backed out during service.
How to Fix It
- Ensure no towel, trim, or magnetic strip is on the front of the dishwasher.
- Verify the cabinet opening clears the door by at least an inch above the unit.
- Open the door, remove the inner door trim, and locate the auto-open vent motor.
- Reseat the motor harness and inspect the push arm for cracks.
- Run the cycle and observe whether the motor engages at end-of-cycle.
- Replace the auto-open vent motor if it does not actuate.
- If motor actuates but door does not pop, replace the broken linkage.
