Bosch Dishwasher Not Draining E24

It’s no secret that the dishwasher is one of the most indispensable appliances in the modern home. But what happens when it starts to malfunction? One common problem is that the dishwasher will not drain properly, resulting in water pooling on the floor. If this happens to you, don’t panic! There are a few things you can do to try and fix the issue yourself before calling for professional help.

Bosch dishwashers have a solid reputation and are especially recognized for their reliability. Despite the fact that these dishwashers are robust, there may be times when your Bosch dishwasher is having an issue, such as the e24 error code.

What is the e24 error code?

According to Bosch, the e24 error message indicates that the dishwasher’s drain filter or pump is clogged. However, there are additional reasons for the problem then a blocked drain hose, kinked hoses, a clogged air gap, or the disposal plug not being removed. If all of these components do not solve the problem, there may be a control board failure that is triggering a false error code.

How to troubleshoot a Bosch dishwasher that is not draining properly

If you have a Bosch dishwasher not draining properly, there are several things you can do to troubleshoot the problem. To begin, unplug the dishwasher before inspecting any internal components.

Step 1: Check it’s not a glitch

The first thing you’ll want to do is check for a glitch. Unplug the dishwasher from the power outlet and then plug it back in after 5 minutes. If the dishwasher does not have a power cord, flip the circuit breaker off and then on again. Once you’ve done this, run a test cycle and see if the dishwasher drains properly.

Another thing to try is holding the start button down, which should also reset the dishwasher and turn on the draining cycle in order to remove water from the dishwasher. If you press the start button but nothing happens, it indicates that it isn’t a bug and that there is a drainage problem to be addressed.

Step 2: Inspect the dishwasher’s drain hose

Once you’ve checked for a power issue, the next thing you’ll want to do is inspect the dishwasher’s drain hose. The first thing you should do is check to see if the hose is kinked or bent in any way. If it is, this could be restricting water flow and causing the dishwasher to not drain properly.

You should also check to see if the dishwasher’s drain hose is connected to the garbage disposal. If it is, make sure that the knockout plug has been removed. The knockout plug is a small, plastic piece that is located near where the dishwasher’s drain hose connects to the disposal. Once you’ve removed the plug, water should be able to flow freely and the dishwasher should drain properly.

Step 3: Clean the sump and filter

If the dishwasher still isn’t draining properly, the next thing you should do is clean the sump and filter. The sump is located at the bottom of the dishwasher and houses the motor, pump, and other components. To access it, you’ll need to remove the dishwasher’s kickplate.

Once you’ve removed the kickplate, you should be able to see the sump. Use a flashlight to look inside and see if there is any food or debris clogging the area. If you see anything, use a brush or your hands to remove it.

You should also clean the dishwasher’s filter. The filter is located just above the sump and can be accessed by removing the upper rack. You should be able to see the filter once you’ve removed the rack. Clean it with a brush or your hands to remove any debris or food that may be clogging it.

Step 4: Check the air gap

The next thing you’ll want to do is check the air gap. The air gap is located on the back of the dishwasher and is responsible for preventing water from backing up into the dishwasher. If the air gap is clogged, it could be causing the dishwasher to not drain properly.

To clean the air gap, simply remove it from the dishwasher and clean it out with a toothpick or other small object. If your dishwasher still will not drain properly after cleaning the air gap, then there may be a more serious problem that will require the help of a professional.


The most likely cause of a dishwasher not draining properly is food or other debris clogging the drain. However, there are a few other potential causes, such as a clogged air gap or a problem with the drainage hose. If you’ve tried all of the above solutions and your dishwasher still won’t drain, then you may need to call a professional for help. Thanks for reading!
