MC/MCU Overload (also displayed as F7EC)
From Tech Sheet W10758925, p.17:
1.Check for obstruction between spin basket and outer tub; check harness continuity and connections between ACU and motor. See TEST #3: Motor Circuit, page 15.
2.Measure the drive motor winding resistance at the main control connector. Expected: 2 to 6 ohms between winding pairs.
3.Rotate the drum by hand and check for free rotation. Inspect the belt and pulley for glaze or wear; a slipping belt mimics a motor fault under load.
