GE Washer Error Code 350

Error code 350 on a GE washer signals a communication fault between the user interface board and the main control board. The two boards have lost the data link required for the washer to operate. This can be caused by a loose harness connection, damaged wiring, or a failed board. The washer will not run until the fault is resolved.

A power reset, performed by unplugging the washer for a few minutes and plugging it back in, may temporarily clear the code if the fault was caused by a momentary signal interruption. However, if there is a physical problem with the harness or a board, the code will return. A reset alone is not a fix for an underlying hardware fault.

Repair costs depend on the root cause. If the fix is simply reseating a loose harness connector, there may be no parts cost involved beyond a service call fee, which typically ranges from $75 to $150. Replacing a wiring harness generally costs $30 to $100 in parts. A UI board or main control board replacement can range from $100 to $300 or more per board, plus labor if using a professional technician.

In some cases, yes. Start by unplugging the washer and inspecting the wiring harness and connectors between the UI board and the main control board. If a loose connector is the cause, reseating it may clear the fault. If the issue involves a damaged harness or a failed board, you will need replacement parts and moderate technical skill to complete the repair.

No. When error code 350 is active, the washer has detected a loss of communication between its control boards and will typically stop operation. Attempting to run the machine in this state is not advisable, as the controls may not function as expected. The fault should be diagnosed and repaired before resuming use.
