Frigidaire Washer Error Code E42

E42 indicates a lid lock device failure on a Frigidaire washer. The control board is not receiving confirmation that the lid lock has engaged, which causes the machine to halt for safety. The fault points to either the lid lock assembly itself or the main control board. Physical obstructions at the lid lock are also a common trigger for this code.

No, you should not continue using the washer while E42 is active. The lid lock is a safety device that prevents the spin basket from operating with an open lid. Running the machine with a compromised lid lock bypasses this protection and could result in injury or further damage to the appliance.

A reset may temporarily clear the E42 code, but the error will return if the underlying problem is not resolved. To reset, unplug the washer for a few minutes and then restore power. If the code reappears immediately or during the next cycle, the lid lock assembly or wiring needs to be inspected and likely repaired or replaced.

In many cases, yes. Start by checking for any debris, clothing, or buildup around the lid lock that could be blocking it from closing fully. If the area is clear, inspect the wiring harness connections at the lid lock for looseness or corrosion. Replacing the lid lock assembly is a moderately straightforward repair that many experienced DIYers can handle, though replacing the main control board is more involved.

If the issue is an obstruction or a loose wire, the fix costs nothing beyond your time. A replacement lid lock assembly typically runs in the range of $20 to $60 for the part, plus labor if you hire a technician. A main control board replacement is more expensive, generally ranging from $100 to $250 or more for the part alone, making professional diagnosis worthwhile before purchasing that component.
