MY AUTOMATIC WASHING MACHINE WON'T WASH?

BOSCH MAXX AUTO WASHING MACHINE.

IT WILL FILL. IT WILL EMPTY, BUT IT WILL NOT WASH. THE DRUM IS NOT TURNING.

IF I HIT THE MOTOR WITH A RUBBER MALLET UNDERNEATH, IT WILL START AND THE DRUM WILL TURN TO DO A WASH.
BUT I WILL HAVE TO TAP THE MOTOR AGAIN TO DO ANOTHER WASH.

IS THE MOTOR ON ITS WAY OUT, OR DOES THE MOTOR NEED NEW BRUSHES?

HOW MUCH WILL IT COST TO PUT RIGHT? ANY IDEAS WELCOME.
