The wash and drain complete normally but the drum never reaches spin speed, leaving the load soaking.
Usually: On the inverter models there are no carbon brushes, so this points at a drain the machine abandoned, a door lock that is not confirming closed, or the motor control board itself.
On the visit: We check the drain path and the lock circuit before touching the electronics, then take readings from the motor and its board so a module is only fitted when the measurements say so.
