A dishwasher drain can have a variety of problems that can arise, especially if they are not well maintained. From dishes not drying, the washer running too long, and spots on glassware to crumbs left on dishes, these common dishwasher issues can be resolved in no time with the help of professionals.

Out of all these potential issues with dishwashers, a dishwasher drain that’s not working properly is still the most common one. It can be incredibly stressful when dishes start piling up. It’s hard to find time to scrub every plate, glass, and cookware after every meal until expert help arrives.

Common Causes of Dishwasher ClogsOpen dishwasher with clean glass and dishes

Here are the most common causes of dishwasher drain clogs to provide a better understanding of the elements that a dishwashing system needs to work efficiently:

Clogged Hose

The dishwasher drain hose connects the dishwasher to the garbage disposal, and food and other particles usually get trapped in it. This happens when dishes aren’t properly rinsed before loading them into the washer. Other times, kinks and clogs can be resolved by getting the aging hose replaced for a better connection.

Detergent Mishap

A dishwasher requires a special type of powder detergent that doesn’t create suds. This makes it easy for the washer to drain completely after each cycle. Using the wrong type of detergent, such as a liquid detergent, results in too many suds, making it harder for the dishwasher to do its job.

Dirty Filters

The dishwasher filter prevents food and other debris from blocking the drain. This gets clogged up over time, which is why it’s important to clean the filter regularly as part of the dishwasher’s maintenance. If it’s already been cleaned thoroughly and it still doesn’t work, it needs to be replaced.

Pump Malfunction

When water remains at the bottom of the dishwasher after the wash cycle is complete, it may be due to a faulty pump. A dishwasher pump expels dirty water into the hose, completing the wash cycle. When the motor is broken, this causes water pump failure, leaving water that is supposed to be drained inside the washer.

Garbage Disposal Blockage

If the garbage disposal is blocked with food particles, it can create a delay in water flowing from the washer through the hose. Running the garbage disposal for a few seconds usually helps remove the clog. Other times, it may be due to a faulty unit, which requires a technician.

Obstructed Air Gap

A sink’s air gap shares a common drain with the dishwasher. If it’s clogged with debris, it can easily cause water to return to the dishwasher, leading to the standing water effect. There is a small cylindrical covering that houses the air gap, and this is where particles and grime often get trapped.

Clogged Line

If the main line is clogged, this may be a bit more complicated than other common dishwasher draining issues. Not finding a clog in the hose or filter can be frustrating, and that’s because the obstruction lies deep underneath. Clearing it requires professional help because it will likely affect other drains in the house.

Worn Plumbing

Plumbing wears out over the years, and the harsh winter months contribute to its normal wear and tear. Some kitchens may need a plumbing overhaul over time, and the cost may depend on the pipes that need to be replaced. Even a new dishwasher won’t work properly with aged plumbing.

Professional Service for Your Dishwashing Unit

While it may be tempting to watch tutorials online on how to troubleshoot a dishwasher that doesn’t seem to be draining properly, this can do more harm than good. Because a dishwasher has various connection points, identifying the culprit without the technical know-how can damage dishwasher parts or even the kitchen’s plumbing system.
