Frigidaire Washer Error Code E43

E43 means the console control board believes the door locking device has failed. The board sent a signal to lock the door but did not receive a valid confirmation in return. The washer will not operate in this condition because running with an unlocked door is a safety hazard. Diagnosis starts with the built-in test (7), reached by turning the program knob 8 clicks clockwise from the start position.

No, you should not attempt to run the washer while E43 is active. The error indicates the door lock is not functioning correctly, and the machine is designed to prevent operation in this state. Running a washer with an unreliable door lock could allow the door to open during a spin cycle, creating a serious safety risk.

A power reset, such as unplugging the washer for a few minutes, may temporarily clear the code if it was triggered by a transient glitch. However, if the door lock assembly or wiring has a genuine fault, E43 will return as soon as the washer attempts to lock the door again. A proper diagnosis using the test (7) diagnostic mode is needed to confirm whether a hardware repair is required.

Some causes of E43 are DIY-friendly, such as reconnecting a loose wiring harness connector at the door lock or checking for a misaligned door latch. However, replacing the door lock assembly or the control board requires disassembly of the machine and comfort working with electrical components. If you are not confident with appliance repair, a qualified technician is recommended.

Repair costs vary depending on the failed component. A replacement door lock assembly typically costs between $30 and $80 for the part, while a new control board can range from $100 to $250 or more. Adding professional labor, total repair costs generally fall between $100 and $400 depending on the diagnosis and your location.
