If you’re experiencing the frustrating issue of a Bosch dishwasher not draining, you’re not alone. A malfunctioning dishwasher can be a real pain, but with a little troubleshooting, you can often identify the cause and fix the problem yourself.
In this article, we’ll explore some of the most common causes of a Bosch dishwasher not draining and provide some helpful solutions to get your appliance working properly again.
Causes of a Bosch Dishwasher Not Draining
Clogged Drain Hose or Filter
One of the most common causes of a Bosch dishwasher not draining is a clogged drain hose or filter. Over time, food particles, soap scum, and other debris can accumulate in the hose and filter, preventing water from draining properly.
To determine if this is the issue, locate the drain hose at the back of the dishwasher and detach it. Check for any visible blockages and use a small brush or cloth to remove any debris. Additionally, remove the filter and clean it thoroughly.
Faulty Drain Pump
Another common cause of a Bosch dishwasher not draining is a faulty drain pump. If the pump is not working properly, it may not be able to remove water from the dishwasher.
To check if the drain pump is the problem, you’ll need to locate it (usually at the bottom of the dishwasher) and inspect it for damage or wear. If you notice any issues, you’ll need to replace the pump.
Defective Garbage Disposal
If your Bosch dishwasher is connected to garbage disposal, defective disposal can also cause drainage issues. If the disposal is clogged or not working correctly, it can prevent water from draining from the dishwasher.
To check if this is the issue, run the disposal and listen for any unusual sounds or grinding. If the disposal is not working properly, you may need to have it repaired or replaced.
Blocked Air Gap
An air gap is a small device that prevents water from flowing back into the dishwasher. If the air gap becomes blocked, it can prevent water from draining from the dishwasher. To check if this is the issue, locate the air gap (usually located on the sink) and remove any visible blockages.
Incorrect Dishwasher Installation
If your Bosch dishwasher was not installed correctly, it may not be able to drain properly. To check if this is the issue, make sure that the dishwasher is level and that the drain hose is not kinked or twisted.
There are a variety of other issues that can cause a Bosch dishwasher not to drain, including a malfunctioning control panel or a defective water inlet valve. If you’ve tried all of the above solutions and are still experiencing drainage issues, you may need to call a professional to diagnose and fix the problem.

Troubleshooting Tips for a Bosch Dishwasher Not Draining
Your Bosch dishwasher is an essential kitchen appliance that makes cleaning dishes easy and convenient. However, it can be frustrating when the dishwasher fails to drain, leaving dirty water in the tub. Here are some troubleshooting tips to help you fix a Bosch dishwasher that is not draining.
1. Check the Drain Filter
The first step to fixing a Bosch dishwasher that is not draining is to check the drain filter. The drain filter is responsible for catching food particles and debris to prevent them from clogging the dishwasher’s drain pump. Over time, the filter can become clogged, preventing water from draining properly.
To check the drain filter, you’ll need to remove the lower basket and unscrew the filter cover. Once you have access to the filter, remove any debris that may be clogging it. Rinse the filter with water and reassemble it back into the dishwasher.
2. Clean the Drain Hose
If the drain filter is not the issue, the next step is to check the drain hose. The drain hose is responsible for carrying water from the dishwasher’s tub to the drain pump. Sometimes, food particles and debris can get stuck in the drain hose, preventing water from draining properly.
To clean the drain hose, you’ll need to disconnect it from the dishwasher and the drain pump. Use a straightened wire coat hanger to remove any debris that may be clogging the hose. Rinse the hose with water and reattach it to the dishwasher and the drain pump.
3. Check the Drain Pump
If the drain filter and drain hose are not the issue, the problem could be the drain pump. The drain pump is responsible for pumping water out of the dishwasher’s tub and into the drain hose. Sometimes, the drain pump can become clogged or malfunction, preventing water from draining properly.
To check the drain pump, you’ll need to remove the dishwasher’s side panel. Once you have access to the drain pump, check for any debris that may be clogging it. If the drain pump is clogged, remove the debris and reassemble the dishwasher. If the drain pump is malfunctioning, you’ll need to replace it.
4. Call a Professional
If you have tried all of these troubleshooting tips and your Bosch dishwasher is still not draining, it may be time to call a professional. A professional dishwasher repair technician will have the tools and expertise needed to diagnose and fix the issue.
