Running rough

The dishwasher is making a grinding noise and is not draining.

Do I need a new float/float fuse?

and an new motor?

How much is a motor?

The dishwasher is grinding and not draining. It began to smell like something was beginning to burn? I have not used it since.

You have to open the pump from the top inside the dishwasher and check for a foreign objects inside or a broken chopper or a broken impeller.
