Why is there standing water in your dishwasher?
If water not draining from the dishwasher is causing issues, the problem often boils down to clogs or maintenance issues with the filter, hose, or drain pump. If you’re dealing with water in the bottom of a dishwasher, it’s often due to one or more of the following reasons:
-
Clogged Filter: A filter can become blocked with food particles and debris, preventing dishwasher water not draining effectively.

Preparing to drain your dishwasher
Before starting any work on a dishwasher that is not draining, ensure all safety steps are covered to avoid any potential mess and be ready to troubleshoot your dishwasher's water-not-draining issue quickly. Knowing how to drain a dishwasher properly starts with understanding some basic preparations, like turning off the power and removing the bottom rack.
-
Before you begin, ensure the power is off, and the bottom rack is removed to access the drain area. Disconnect the dishwasher from its power source—unplug it or switch off the breaker. Dishwashers combine water and electricity, so taking this precaution is crucial.
-
Next, remove any dishes and the bottom rack to easily access the drain area. Some models have a “Cancel” or “Drain” button that, when pressed, initiates a manual drain cycle, so check your dishwasher’s manual to see if this option is available.

Then, to prevent spills, place a towel on the floor around the dishwasher and have a sponge and a small bucket handy to clean up any remaining water.
How to drain a dishwasher step-by-step
Here’s a straightforward guide to how to drain a dishwasher and efficiently tackle stubborn standing water issues. If you’ve checked the basics and still see water pooling, these steps can help solve the problem. Along the way, use the recommended hand tools such as pliers and screwdrivers or other accessories listed in this guide that might be required.
Step 1. Turn Off the Electricity
To ensure safety, start by disconnecting your dishwasher from its power source. Unplug it directly or switch off the circuit breaker to prevent electric shock.
Step 2. Remove Standing Water
Soak up any water in the bottom of the dishwasher to get a clear view of any visible blockages. Use a sponge or towel, or use a small bucket if there’s a larger amount. This clears the area and lets you look at any components causing the issue. See our range of buckets for cleaning and to facilitate easy water removal.
Step 3. Clean the Filter
The filter is typically found at the bottom. Once you’ve cleared the visible water, check the filter at the base of the dishwasher and ensure it’s free of food particles and debris, which is the most common reason for water not draining from the dishwasher units effectively.
Twist it off, rinse it under warm water, and scrub off any remaining bits. If this is heavily clogged, clearing it may solve your drainage problem. Consider using a wire brush or a drain cleaner to clear stubborn debris. Check out wire brushes for this task.
Step 4. Inspect and Clean the Drain Hose
Find the drain hose, usually located under the dishwasher or at the back if it’s freestanding. Use pliers to gently detach it from the drain connection, and check for blockages inside. You can use water pressure or a drain cleaner to flush out clogs. Reconnect the hose once it’s clear. Explore plier options to make this job more manageable.
Step 5. Examine the Garbage Disposal Connection
If your dishwasher drains through a garbage disposal, ensure the disposal is clear. Running it for 30 seconds can remove any potential blockages. This connection can easily back up if clogged, so double-check this step.
Step 6. Check the Drain Pump
If water still won’t drain, the pump could be the culprit. The drain pump is usually accessible via the bottom panel, where you can check for visible obstructions. If dishwasher water is not draining, the pump could be damaged or faulty, it may need replacing to restore full functionality.
