Hi,
MCU FAILURE 1.
Check for proper installation, verify the unit is not located near
a source of heat and has proper ventilation. If the problem persists then You need
to replace the MCU unit.No other way.And it won't cost that much May be Maximum
200$ Thank You
If the heat sink gets too hot, the Motor Control Unit (MCU) will stop the
motor, the MCU will communicate this failure to the Central Control Unit (CCU),
then the CCU will reset the MCU.
If the condition continues four times, the F31 code will show.
2. Unplug washer or disconnect power.
3. Check wire harness connections to the MCU, the motor, and Central Control
Unit (CCU).
4. Check the drive system for any worn or failed components.
5. Plug in washer or reconnect power.
6. Check the MCU by looking for operations of the drive motor.
7. Check the drive motor for powered rotations

Sounds like a reasonable diagnosIs. Will I be able to to procure a CMU? I am reasonably handy at repairs, should I DIY?
