If your dishwasher won't drain, the issue often lies with blocked filters, clogs in the drain hose, or problems with the garbage disposal. First, check and clean the filter at the bottom of your dishwasher. Next, inspect the drain hose for kinks or blockages and ensure it's properly connected. If you have a garbage disposal, run it to clear any potential clogs. These steps solve most drainage issues, but if the problem persists, you may need to consult a professional.
