The diagnostic test did not spin at a very high speed. All connections are encrypted.. I am thinking motor control board was bad. I ran a diagnostic spin and everything seemed good. I ran a tiny load and it completed the cycle without issue. E58 emerges after the second modest load. How can I pinpoint the source of this issue?
You should also double-check the motor winding and harness resistances. These symptoms are most likely caused by the motor control board. We can rebuild faulty control board modules, here is the link:
