The F02 error code indicates a drain issue. It can be due to a drain catch. To solve the issue, you need to get inside your washer. Tilt the washer backwards and lean it agsainst the wal at an angle of approximately 45 degrees. Undo the three screws at the front panel’s bottom, then pull it down and off. You will see a plastic twist cap right under the tub. It is mounted to the wassher’s bottom and has a diameter of 3”. Remove the cap and check the drain catch for debris. If the catch and the hose are all right, the drain pump may have gone faulty. You may need to replace it.
