HP M527 ADF makes grinding noises. Functions fine, but feels as if something is misaligned or rubbing. Took out rollers and cleaned them. Sound still there.

SOURCE: Grinding/Rubbing noise?

the unit has a "food chopper" inside the pump sump. it is to chop up "food" items and not bones, seeds or other items. you can keep running the unit and see if after 2 or 3 loads the noise goes away. ie: the item get chopped up small enough to go out the drain.
if it doesnt go away, then you will need to get into the wash pump and see what is stuck in the sump.
its not hard to take apart and you will find whatever shouldnt be in there.
