Dishwasher noise and no water

My mom’s dishwasher makes is a grinding sound and no water when it starts or after a few minutes. This happens on all selections. Turned it off so as not to burn it up. Can this be repaired or must it be replaced?? Please answer soon-am going to visit Mom on Sunday.Thank you.
