Why Your Dishwasher Stopped Draining and How to Fix It

There’s no denying the convenience of a dishwasher. But when you open the door only to find murky water staring back at you, that convenience quickly turns into frustration. If your dishwasher stopped draining, take heart. Many experience this household inconvenience, and in many cases, the solutions are more straightforward than you might think.

Understanding Why Your Dishwasher Stopped Draining

When it comes to a non-draining dishwasher, there’s usually a good reason behind it. Understanding the possible culprits can guide you toward the best solution.

Drain Filter Is Clogged

At the heart of your dishwasher’s draining system is the drain filter, a critical component responsible for catching large particles of food and debris. This filter works hard, but it can’t do its job if it becomes a cesspool of muck and gunk. Severe clogs can even hinder dishwasher cleaning performance.

While it’s doing its job catching large debris, over time, this can lead to blockages. An obstructed filter can prevent water from draining and even leave a nasty odor. Gently remove the filter and give it a thorough rinse under running water. Using a soft brush can be beneficial for stubborn residues. To ensure your dishwasher functions optimally, make this cleaning a regular routine, perhaps marking it on your calendar every few weeks.

Clogged or Kinked Drain Hose

The drain hose is like the lifeline for your dishwasher’s draining mechanism. It transfers all the dirty water out and into your home’s drainage system. But if this hose gets a kink or becomes obstructed, it can become an unwanted reservoir.

Take a peek behind your dishwasher and inspect the drain hose. It should have a smooth, arc-like curve, free from any tight bends. If you spot a kink, straighten it out. For blockages, you might need to detach the hose and flush it with water. Regular inspections can help keep this hose in peak working condition.

Garbage Disposal: An Unexpected Player

Many homeowners are unaware of the link between their garbage disposal and dishwasher. They share a common drain, which means if one’s blocked, the other can suffer. If you’ve been using your disposal a lot and haven’t run it recently, it might be the hidden cause behind your dishwasher’s woes.

Before diving into any troubleshooting, ensure the disposal is turned off. Then, give it a thorough run to clear out potential obstructions. Making it a habit to run your garbage disposal regularly can help maintain an unblocked pathway for both appliances.

The Air Gap Dilemma

Older kitchens or those in areas with specific plumbing codes often have an air gap. It’s a small device sitting atop the sink, preventing dirty water from backflowing into your dishwasher. However, if you notice water spewing from it, there’s a high chance it’s clogged.

To address this, remove the air gap cap and inspect the inside. Often, debris or buildup can block the pathway. Cleaning it out can restore proper water flow. Regularly checking the air gap and keeping it free from obstructions can help in smooth draining.

Drain Pump Failure

The drain pump is like the heart of your dishwasher’s drainage system. When it’s working correctly, it efficiently expels water. But if it malfunctions, you’ll likely find standing water in the bottom of the dishwasher.

If you’re hearing unusual sounds or suspect the pump is at fault, it’s essential to check for any obstructions. Sometimes, foreign objects or accumulated debris can hinder its function. If after a thorough inspection and cleaning it still doesn’t work, consider consulting a professional. The pump might need replacement.
