Have you ever had a long day at work and finally came home to make a nice, healthy dinner for you or your family? If so, the last thing you want to do after finishing your meal is roll up your sleeves and spend an extra 30 minutes scrubbing pots and pans. With that being said, owning a dishwasher can be very beneficial in saving you time and stress. However, the appliance isn’t completely immune to malfunctions.

Common Causes of a Dishwasher That Won’t Drain

One of the most common issues is the dishwasher not draining properly. If your dishwasher won’t drain, here are some of the potential causes:

1. Garbage Disposal Problems

Check for any obstructions in the drain or garbage disposer. Often times, food and other objects can get caught in the disposer and cause water to build up as a result of a clogged drain.

2. Air Gap Issues

A dishwasher air gap is found at the back edge of the sink near the faucet, it allows air into the dishwasher so it can properly drain without creating a vacuum. If it gets clogged or blocked, it can cause drainage problems.

3. Check the High-Loop

If your dishwasher doesn’t have an air gap, it likely has a drain hose that is looped upward. It’s usually attached to the bottom of the countertop close to the sink. If the loop becomes detached, it can cause water to rise from not draining properly.

How to Troubleshoot a Dishwasher That Won’t Drain in 3 Steps

Step 1. Check the drain screen

At the bottom of the dishwasher tub, there should be a drain screen. It looks like a mesh strainer and is used to filter out solid debris built up in the dishwasher. Sometimes, there can be clear plastic lids, glass, or labels that can be hard to see unless you look closely, so make sure nothing is clogging it.

Step 2. Clean the filter

There are many different dishwashers filter designs . Some have a simple screen, and some have removable filters below the screen that require a little more effort to clean. The best thing to do is check the appliance manual for instructions on how to clean the filter properly.

Step 3. Inspect the drain hose

The drain hose is a plastic tube that runs from the bottom of the dishwasher to the garbage disposal, air gap, or sink drain, depending on the setup. The first step is to turn the power off the dishwasher by pulling out the plug or switching off the breaker to the dishwasher circuit. Then, remove the toe-kick panel and loosen the hose clamp that’s connected to the dishwasher pump. Next, clean the end of the hose thoroughly. If you’re not able to blow through it, this means the hose is still clogged and you should replace it.
