With the lack of any details (like model etc) it's pretty hard to say anything here....
I would still check the brushes first, if not that it's possibly the motor control module (expensive) and after that anything else becomes really expensive!
This video shows a hotpoint motor, older indesits had identical motors and even the newer ones the principle is the same

Make sure you disconnect the mains if you are going to check them yourself, But I really would recomend getting somebody else who knows what they are looking for to check them.
