Could a failing Main Control Board (ACU) cause the WHIRLPOOL WASHER WFW5620 NOT DRAINING to have symptom: Repair?

The control board is failing to properly energize and control the direct drive motor, resulting in stuttering and a clanking noise as the motor attempts to spin but lacks sufficient power or consistent signal. The inability of the display to function, except for the control lock, further indicates a corrupted or faulty control board, especially after a power event. Diagnostic mode confirmed the motor itself was functional, isolating the issue to the control logic.

// ENGINEER'S LOG

The Whirlpool front-load washer, model WFW5620, exhibits symptoms of a compromised main control board. The drum stutters and clanks during initial spin attempts, akin to a weak starter, despite the drum spinning freely by hand. This points to a failure in the motor's power delivery or control signals. Concurrently, the LCD remains off and unresponsive to button presses, with the exception of the control lock function, which is a strong indicator of a control board malfunction, potentially exacerbated by a power outage. The unit is a direct drive, ruling out mechanical transmission issues. The main control board (ACU) is the primary suspect for both the motor control failure and the display/interface issues. // SAFETY NOTE: Ensure unit is disconnected from all power sources before inspection. Forensic analysis is for component identification only.
