Why is My Dishwasher Not Draining?

Have you ever opened your dishwasher and found a pool of water at the bottom? It’s like finding a mini swimming pool in your kitchen. As an appliance repair expert, I've fixed my dishwasher, my neighbor's, and countless others for my clients.

In this article, I’ll walk you through the common reasons why your dishwasher isn’t draining and how to fix it. So, roll up your sleeves, grab your toolbox, and let’s dive in!

Clogged Filter

Sometimes, your dishwasher may not drain because the filter is clogged with food debris.

Common Cause

The filter might be clogged with food debris.

Solution

Check and clean the dishwasher filter. It’s usually at the bottom of the dishwasher. Remove any debris and rinse the filter under running water.

Personal Story

I remember my friend Sarah called me one day, panicked because her Bosch dishwasher had standing water. We found the filter clogged with spaghetti bits. A quick clean, and her Bosch was back in action, draining like a charm!

Blocked Drain Hose

Another reason could be a blocked or kinked drain hose, causing water to stay in your dishwasher.

Common Cause

The drain hose might be blocked or kinked.

Solution:

Inspect the drain hose for any blockages or kinks. Disconnect the hose and clean it out if necessary.

Personal Story

My neighbor, Tom, had a Miele dishwasher that wouldn’t drain. Turns out, the drain hose was kinked from moving the dishwasher. We straightened it out, and Tom’s Miele was draining perfectly again.

Garbage Disposal Connection

If your dishwasher is connected to a garbage disposal, make sure the plug inside the disposal is removed.

Common Cause

The plug inside the disposal might still be intact.

Solution

Ensure the knockout plug in the garbage disposal (where the dishwasher drain hose connects) has been removed.

Personal Story

Once, I helped a client with their Beko dishwasher. The knockout plug was still in the garbage disposal. We removed it, and their Beko was draining smoothly again.

Clogged Air Gap

A clogged air gap can also stop your dishwasher from draining properly.

Common Cause

The air gap might be clogged.

Solution

Clean the air gap, usually located near the sink. Remove the cap and clean out any debris.

Personal Story

My GE dishwasher was giving me a headache because of a clogged air gap. After a quick clean, my GE dishwasher was back to its old self, draining without any issues. I was so happy, I treated myself to a movie night. Thankfully, it wasn't a case of "ge dishwasher not starting."

Faulty Drain Pump

A malfunctioning drain pump can be the culprit behind your dishwasher not draining.

Common Cause

The drain pump might be malfunctioning.

Solution

Listen for any unusual sounds from the pump during the drain cycle. If the pump is not working, it may need to be replaced.

Personal Story

My friend Mike’s Café dishwasher had a faulty drain pump. We replaced the pump together, and it felt like a victory when his Café started draining properly again.

Drain Valve Issues

A stuck drain valve could also prevent your dishwasher from draining.

Common Cause

The drain valve could be stuck.

Solution

Check if the drain valve can move freely. If it's stuck, it might need to be replaced.

Personal Story

I once fixed my neighbor Lily’s GE dishwasher. The drain valve was stuck. We replaced it, and her GE dishwasher was as good as new.

Electrical Issues:

Sometimes, electrical problems might be the reason your dishwasher isn’t draining.

Common Cause

There might be a problem with the electrical connections or controls.

Solution

Ensure all electrical connections are secure. If the control board or timer is faulty, it may need professional repair or replacement.

Personal Story

A client’s Miele dishwasher wasn’t draining due to a loose wire. We secured the connection, and the Miele was back to draining without any hitches.

Incorrect Installation

Improper installation can lead to draining issues in your dishwasher.

Common Cause

The dishwasher might not be installed properly.

Solution

Verify the dishwasher is installed correctly, following the manufacturer's instructions.

Personal Story

I helped my sister install her new Bosch dishwasher. We followed the instructions to a tee, ensuring it drained perfectly from day one.
