Dishwasher intermittently not draining DW80K5050US

For about 3 months now, my Samsung dishwasher will randomly not drain after the cycle has finished. This happens about 70% of the time, with that percentage increasing. My dishwasher does not have a filter on it, so I removed the mesh screen and clean out everything that was under it. the lowest point where the pump drains from is clear and has no debris. I removed the pump and tested it. It works just fine. I've replaced the drain line and snaked the drain. 

There is absolutely no reason this 4-year-old dishwasher is doing this.

That is definitely frustrating! I'd recommend checking out the following troubleshooting steps:

    1. Inspect the dishwasher's drain connection at the sink.

      When your dishwasher isn't draining, it could actually be your sink's drain that's causing the issue. If you're using a garbage disposal, make sure it is clear of food waste and not clogged.

      If your dishwasher is connected directly to the drain, look down the drain and check if there is any visible blockage.

      If the dishwasher or garbage disposal was recently installed, the disposal cap may be the cause of the blockage as well, so make sure it's removed.

    2. Check the drain hose.

      The most common reason for a drain issue right after installation is that the dishwasher is sitting on top of its own drain hose, pinching it shut.

      The next most common reason is that the drain hose is either not connected to an air gap, or does not have a "high loop" where part of the drain hose is above where it is connected to the sink (see image). Without either of these, water may backflow into the dishwasher and fail to drain correctly. Make sure to install the drain hose according to local regulations, which may vary.

      You'll also want to make sure it's not kinked or bent, especially if there's been any recent changes to the drain hose or its connection to the sink. If it's kinked or bent, straighten it out.

      If the drain hose is damaged to the point it cannot be straightened out, visit our Support Center to request service.

    3. Run water in the sink that the dishwasher is connected to.

      Run water for about 30 seconds, and then verify if the sink drains. If it does not, the issue is with the home's plumbing and not with the dishwasher itself. Contact a plumber for assistance.

Use caution when cleaning the drain, because there may be sharp debris.

    1. Clean the drain, filter, and sump in the tub.

      Some models have removable parts in the filter and drain area to help you clean more thoroughly. If your model has these removable parts, instructions will be in your user manual. Even if the parts are not removable, clearing the area of food and debris is necessary to prevent drain and odor issues.

    2. Confirm your drain line is not frozen.

      If it's possible that your water or drain lines are frozen, leave the door under the sink open or let the area in question warm up somehow. If the lines continue to be frozen, contact a plumber.

*Since frozen water or drain lines are not covered under warranty service, we recommend to only request service if you know the lines are not frozen.*
