Follow the official owner checks
Try the following method to resolve: Is the drain hose kinked? Is the drain hose clogged? Cycle power to the control to reset the washer: Much like a computer, resetting the washer control can sometimes solve the issues you are experiencing. To reset the washer control panel, it needs to be disconnected from the power source for 5 minutes. If your washer is plugged into an outlet, simply unplug the unit for 5 minutes and then plug the unit back in.
Expected: Only the user-accessible condition identified by the official source is corrected.
If not resolved: Stop repeated resets and arrange qualified service if the code returns or the source directs service.
