The F54 fault code occurs when there is a high current load on the motor module. It can be detected by  the main/motor control board.

Where does the problem occur?

• Wire harnesses (lose or damaged
• connections)
• Friction of the basket
• Faulty RPS sensor board
• Faulty stator
• Faulty motor/machine
• control board
• Unstable or loose tub bearing

The problem can occur due to an overloaded tub and friction. Check the tub by rotating it manually to ensure it spins freely. If there is friction, you need to check the washer’s bottom center area. Not unlikely, there is a foreign object stuck in there and preventing it from spinning properly
