My Maytag quiet series 300 dishwasher has started

Customer Question

My Maytag quiet series 300 dishwasher has started intermittently making a loud grinding noise. I ran a cycle with dishwasher cleaner, but the symptom continues. What should I try next? Why is it making this noise?

Does it make the noise during wash or when it is pumping out?

Expert:  Kelly replied 1 year ago.

The tech sheet for your model is attached. Can you retrieve any stored error codes and post them, please?

Customer: replied 1 year ago.
during wash, at least shortly after turning it on and the "washing" light is green.

Does it stay noisy for the entire cycle?

Customer: replied 1 year ago.
No, the grinding noise is only intermittent, maybe only 10 seconds, maybe longer or not at all.
Expert:  Kelly replied 1 year ago.

There is probably something stuck in the chopper area.

May I please have your complete model number so I am able to provide you with accurate, model specific information?

Customer: replied 1 year ago.
I can't find a model number on the door and I do not have a manual. There is a Maytag sticker on the top left inside that has numbers on it , but none of them are labelled. Perhaps one of them is the model number?

It is on that tag and will look like MDB1234ABC

In the diagram at the link below, the noise is probably coming from the number 6 wash impeller or the number 9 chopper. Are you able to disassemble for inspection?
