. Step 2: Clean the Filter and Drain Basket A dirty filter is the most common cause of drainage issues. Locate the Filter: It’s usually found at the bottom of the tub, near the spray arm. Remove and Rinse: Twist the filter (usually counter-clockwise) to unlock and lift it out. Scrub: Use an old toothbrush and warm, soapy water to remove grease and food particles. Rinse thoroughly before reinstalling. Step 3: Check the Sink and Garbage Disposal Since many dishwashers drain through the kitchen sink's plumbing, the issue might not be the machine at all. Run the Disposal: Turn on your garbage disposal to clear any food trapped in the sink drain. Check the Knockout Plug: If you recently installed a new disposal, ensure the "knockout plug" in the dishwasher connection was removed. Step 4: Use a Natural DIY Unclogger For mild clogs further down the pipe, a vinegar and baking soda mixture can help break down grease. Apply Paste: Mix a small amount of baking soda with water to make a paste and pour it into the drain opening. Add Vinegar: Pour 1 cup of white vinegar over the baking soda. It will begin to fizz. Wait and Flush: Let it sit for 10–15 minutes, then flush the drain with a pot of very hot (but not boiling) water. Step 5: Inspect the Drain Hose If the clog persists, the problem may be in the hose itself. 11 sites How to Unclog a Dishwasher Drain in 5 Steps - Whirlpool How to unclog a dishwasher.
