LG Dishwasher Grinding Noise LDF7920ST LDF7810BB LDF7920WW

If your LG Dishwasher is making grinding noise when washing, you can fix the problem by cleaning the chopper blade. It's quite easy and costless.

In my case, a little piece of glass from a broken glassware was stuck in the grid (see pictures after cleaning). The noise was loud and horrible. Now, everything works perfectly and silently.



WARNING

- DO NOT overtightened the screws on case and filter assembly because you can very easily snap the plastic tabs (réf. https://www.applianceblog.com/mainforums/threads/58066-LG-Dishwasher-LDS4821ST-floater-reservoir-overflowing).



- When you remove the impeller, please note that you must unscrew counterclockwise. Do not force by trying to unscrew clockwise.
