GE Dishwasher Error Code dLF

dLF stands for door latch failure and is a critical fault code. It means the control board cannot detect continuity through all three pins of the door latch circuit with the door closed. The dishwasher will not operate until the fault is resolved.

No. The dLF code is a critical fault that locks out dishwasher operation. The machine will not start a cycle because it cannot confirm the door is securely latched. Running a dishwasher with an unverified latch condition creates a risk of the door opening mid-cycle, which can cause water damage to the floor and surrounding cabinetry.

Close the dishwasher door fully and disconnect the wiring harness connector from the door latch. Set a multimeter to continuity or resistance mode and probe all three pin combinations on the latch side of the connector. All three pins should show continuity with the door latched. If any pin pair shows an open circuit, and the harness wiring itself is intact, the door latch assembly has failed and should be replaced.

Start by inspecting the wiring harness that runs to the door latch, checking for loose connectors, broken wires, or corrosion. With the door closed, use a multimeter to check for continuity across all three pins of the door latch connector. If the harness passes that test, the door latch assembly itself needs to be replaced. The latch is typically located on the door frame and is accessible after removing the inner door panel.

A replacement GE door latch assembly typically costs between $25 and $60 for the part. If you are comfortable removing the inner door panel and working with a multimeter, this is a DIY-friendly repair. Professional labor to diagnose and replace the latch generally adds $100 to $200, making total professional repair cost roughly $125 to $260 depending on your market and the specific model.
