What should I do if my dishwasher stops draining?
If your dishwasher isn't draining, you will need to check the sink's drain for clogs and blockage caused by food, debris and waste, and check the drain hose connection to the sink for nicks, bends, kinks or other damages. Depending on your local regulation, the hose may be connected to the sink with an air gap, or have a high loop to prevent backflow and ensure proper drainage.
Please note:
- Error codes such as 5C, 5E, OC, or OE mean there is a drain or overflow error. You can learn about other error codes in our Dishwasher error codes FAQ.
- On models that do not display codes, certain combinations of blinking or flashing lights (such as Heavy and Auto) also indicate a drain or overflow error. Search for your user manual to find out which combinations indicate the error.
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 your dishwasher is connected directly to the drain, look down the drain and check if there is any visible blockage.
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.
Run water in the sink
Please note: Use caution when cleaning the drain, as there may be sharp debris.
Clean the drain and filter
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.
Please note: Even if the parts are not removable, clearing the area of food and debris is necessary to prevent drain and odor issues.
