How to Fix a Blocked Dishwasher Drain Pipe A dishwasher that won't drain is a common kitchen headache, but most of the time, it’s a simple fix you can handle yourself.

If your dishwasher drains into a garbage disposal unit, the blockage often stems from a simple oversight. When a new disposal is installed, a knockout plug (a small piece of plastic or metal) is left inside the drain inlet to seal it if a dishwasher isn't hooked up.
