Signs and Causes of Dishwasher Drain Problems: Troubleshooting Tips

Regularly maintaining your dishwasher is crucial to ensure it functions efficiently and hygienically. However, if your dishwasher isn't draining properly, you may encounter stench, water pooling at the bottom, and other issues. In this article, we will explore the signs of a malfunctioning drain, possible causes, and effective troubleshooting methods.

Signs Your Dishwasher Isn't Draining Properly

When the draining process is not working as it should, it can cause a variety of issues affecting your daily routine. Some of the signs include:

A stench emanating from the washer

Water remaining at the bottom of the dishwasher even after the cycle has ended

The presence of unsightly, wet dishes or items that haven’t dried properly

Why Your Dishwasher Isn’t Draining Properly

There can be multiple reasons for poor drainage in a dishwasher. Some of the primary causes include:

Container Design and Loading

Flat- vs. Non-Flat Bottomed Containers:

Many dishes and bowls have a lower middle, making them similar to the Great Salt Lake, where water can pool. This can lead to poor drainage. Here are some solutions:

Use or Purchase Flat-Bottomed Containers: Opt for newer or more modern dishware with flat bottoms as they allow water to drain more effectively.

Proper Loading: Arrange non-flat bottom containers so water does not pool. For instance, tilt them to ensure any accumulated water can drain out.

Manual Drying: After the cycle ends, open the dishwasher and shake out excess water in the sink. Then, place the items back in the dishwasher to dry. Alternatively, if everything is already cool, shake off the water and allow them to dry on a preferred dish drainer or drying pad.

By following these simple steps, you can significantly improve the draining performance of your dishwasher.

Blocked Drain System

Another common issue is a blocked drain. Plastics grids at the bottom of most models need to be cleaned regularly. If unable to access these, use gentle cleaning methods to ensure the drain system remains clear and unobstructed.

Filter and Float Maintenance

Additional maintenance may include cleaning the spray arm filter and float.

Spray Arm Filter: Check if the spray arm filter is clogged with food particles or other debris. Clean it thoroughly to ensure proper water flow.

Float Component: Ensure that the float mechanism isn't stuck or malfunctioning. A clogged or incorrect float can prevent the water from draining properly.

If you've taken care of these issues but still experience drainage problems, it may be time to seek professional assistance from a repairer. A qualified technician can help identify and resolve more complex issues that may be affecting your dishwasher's performance.
