Dealing with a dishwasher overflowing not draining scenario can be both stressful and messy. But don’t worry, this issue is common and solvable. In this comprehensive guide, we will walk you through each step to get your dishwasher back to its optimal condition.

Identifying the Issue
Before proceeding, make sure to confirm that your dishwasher is indeed overflowing and not draining. Check the dishwasher’s base for pooled water and inspect for overflow signs.
Things You’ll Need
You will need the following tools to address a dishwasher overflowing not draining issue:
Safety Precautions
Your safety is paramount. Before you even think about opening up the dishwasher or fiddling with its internal parts, it’s crucial to disconnect the appliance from its power source. This ensures that you are safe from any electrical hazards.
To do this, locate the power cord that is usually situated at the back of the dishwasher, and carefully unplug it from the wall socket. Additionally, if your dishwasher is hardwired, turn off the circuit breaker related to the dishwasher to eliminate any risks of electrical shock.
Unclogging the Drain
First, make sure to remove all dishes and utensils from the dishwasher. This clears the space and allows you easier access to the parts you will need to examine and possibly clean.
Use towels to soak up any standing water that might be at the base of the dishwasher. Doing so will give you a clearer view of the drain and will prevent any potential spills.
Once the area is dry, locate the filter at the base of the dishwasher. Use a screwdriver to gently remove the screws securing the filter in place.
With the filter removed, wash it thoroughly using a mixture of warm water and dish soap. Use a soft brush to dislodge any trapped debris. This cleaning often solves minor drainage issues.
After cleaning the filter, return it to its original position within the dishwasher. Use the screwdriver to re-secure the screws.
Checking the Drain Hose
The drain hose is usually located at the back of the dishwasher. You may need to pull the dishwasher slightly out from its position to get better access to the hose.
Once you’ve located the drain hose, use a screwdriver to loosen the clamp that holds the hose in place. This will allow you to detach the hose for inspection.
After detaching, carefully inspect the hose for any clogs or obstructions. If you find any, use a long, flexible brush or pipe cleaner to remove the clogs.
Once you are certain that the hose is clear, reattach it to its original position. Use the screwdriver to tighten the clamp, ensuring the hose is securely fastened.
Assessing the Pump
If you’ve tried all the previous steps and your dishwasher is still not draining, it’s likely that the problem may be with the pump. The pump is responsible for circulating water in the dishwasher and expelling it during the draining cycle. A faulty pump could be the root cause of your dishwasher not draining.
Due to the complexity involved in diagnosing and replacing a dishwasher pump—which may include electrical work—it’s recommended to seek the services of a certified technician for this particular issue.
