The E07 error occurs when there is a motor issue.
To access the motor, please, get the washer from under the counter and take off the back panel. The motor will be at the drum’s bottom.
Make sure that the motor’s wiring is not loose or damaged.
If the wiring is ok, check the motor’s carbon brushes at its back and see how worn they are. If they are worn down too much, replace the brushes.
