Hi
Grinding noise is due to a cracked impeller which can be accessed by removing the spray arm. Sometimes a poor washing complaint is common after this wash impeller has cracked. Remove power first before investigating.
The motor shaft has started to rust and swells out and this swelling cracks the upper impeller. Most times a new seal and impeller kit can cure this complaint but sanding and cleaning of motor shaft is required before replacing the new seals and impellers.
Please do rate this solution as FixYa and revert for further assistance.
Thanks
