My dishes, especially glasses, are often getting dried sediment left on them after a cycle in the dishwasher. I run it with vinegar every couple months but that doesn't seem to be enough. I want to clean the filter and surrounding assembly similar to what's done in the YouTube video "Repair Dishwasher For Cleaner Dishes - Maintenance Clean Fix Whirlpool Kenmore" but can't tell how to access mine. The plastic bolt in the very middle will turn and turn but not come out.
I've looked through the manual and a RepairClinic “Troubleshooting” page that comes up when I google the model number, but they don't seem to be much help, unless I missed something from them.
