What F37 (Auto Open Door Error) Means
F37 displays when the Auto Open Door feature - which automatically cracks the door open at the end of certain cycles to help dishes air-dry - doesn't function correctly, per LG's dishwasher Help Library article. LG suggests checking for interferences near the door before assuming a hardware fault, and states inspection by a service technician is needed if that doesn't resolve it.
Common Causes of F37 (Auto Open Door Error)
- Cabinetry or nearby object physically blocking the door's automatic opening path
- Auto Open Door mechanism component has failed
🔧 One Safe Check You Can Try
Check that nothing is blocking the door's path of travel near the top or sides - cabinetry that's too close, an item left on the counter above the door, or an item on the dishwasher's own control panel - and clear any obstruction before running another cycle.
⚠ Why You Shouldn't Go Further Than That
- If clearing any obstruction near the door doesn't resolve F37, LG recommends service inspection, since the auto-open mechanism itself may need repair rather than further clearance checks.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
