Encountering error codes can be frustrating, especially when it disrupts the smooth operation of your Bosch dishwasher.

The E24 error code, specifically, signals a drainage issue that demands immediate attention.

This comprehensive guide is designed to walk you through the steps to resolve the Bosch dishwasher E24 error code effectively.

Follow these troubleshooting methods carefully to restore your dishwasher’s functionality and get back to hassle-free dishwashing in no time.

Common Causes of Bosch Dishwasher E24 Error Code

The Bosch dishwashers E24 error code commonly arises due to blockages or obstructions in the drainage system. This can be attributed to a clogged filter, debris accumulation in the drain pump, or an obstructed drainage hose.

Additionally, improper installation leading to incorrect alignment of the drainage system or issues with the dishwasher’s internal components can trigger this error.

Insufficient water pressure or a malfunctioning pump can also contribute to the E24 error, disrupting the dishwasher’s drainage process and prompting the error code.

Step-by-step Instructions on Fixing E24 Bosch Dishwasher Error

Let’s take a closer look at each of these potential problems and the steps to resolve them

1. Clean the Filter

The first step in troubleshooting the Bosch dishwasher E24 error code is to clean the filter. Over time, debris and food particles can accumulate in the filter, causing a blockage and preventing proper drainage. To clean the filter, follow these steps:

  1. Locate the filter at the bottom of the dishwasher, typically in the center or rear.
  2. Twist the filter counterclockwise to remove it from the dishwasher.
  3. Rinse the filter under running water to remove any dirt or debris.
  4. Use a soft brush or toothbrush to gently scrub the filter, if necessary.
  5. Reinsert the filter into the dishwasher and twist it clockwise to secure it in place.

After cleaning the filter, restart the dishwasher and check if the E24 error code has been resolved. If not, proceed to the next step.

2. Check the Drain Pump

If cleaning the filter did not resolve the E24 error code, the next step is to check the drain pump. The drain pump is responsible for pumping out the water from the dishwasher during the drain cycle. A faulty or clogged drain pump can trigger the E24 error code.

Here’s how to check the drain pump:

  1. Disconnect the dishwasher from the power source.
  2. Remove the bottom panel of the dishwasher to access the drain pump.
  3. Inspect the drain pump for any debris or obstructions.
  4. Use a flashlight to check if the impeller is damaged or clogged.
  5. If there are any obstructions, remove them carefully.
  6. Test the drain pump by manually turning the impeller to ensure it spins freely.
  7. Reinstall the bottom panel and reconnect the dishwasher to the power source.

Reset and try running a cycle to see if the E24 error code is resolved. If not, move on to the next step.

3. Check for Kinked Hoses

A kinked or bent drain hose can also trigger the Bosch dishwasher E24 error code. Inspect the drain hose for any kinks or obstructions that may be preventing proper water flow.

Here’s what you need to do:

  1. Disconnect the dishwasher from the power source.
  2. Locate the drain hose at the back of the dishwasher.
  3. Check the entire length of the hose for any kinks or bends.
  4. Straighten out any kinks or bends in the hose.
  5. Ensure that the hose is not trapped under or behind the dishwasher or any surrounding objects.
  6. Reconnect the dishwasher to the power source and run a cycle to check for the error code.

If the E24 error code still persists, proceed to the next step.

4. Clean the Dishwasher

Sometimes, a dirty dishwasher can cause drainage issues and trigger the E24 error code. Cleaning the dishwasher thoroughly can help resolve the problem.

Follow these steps to clean your Bosch dishwasher:

  1. Empty the dishwasher of any dishes or utensils.
  2. Remove any removable parts, such as racks and silverware baskets.
  3. Wipe down the interior of the dishwasher with a damp cloth or sponge.
  4. Pay special attention to the spray arms and ensure they are free from any blockages.
  5. Use a dishwasher-safe cleaner or a mixture of vinegar and baking soda to clean the interior.
  6. Replace the removable parts and run a cycle without any dishes to rinse the dishwasher.

After cleaning the dishwasher, check if the E24 error code has been resolved. If not, proceed to the next step. 

5. Check the Air Gap / Disposal / S-Trap

The air gap, disposal, or s-trap may also be the cause of the E24 error code. Check these components to ensure they are functioning properly.

Here’s how:

  1. Inspect the air gap, whose location can vary depending on model, but it is usually located on the countertop near the sink.
  2. Remove the cover of the air gap and clean out any debris or blockages.
  3. If you have a garbage disposal system, check it for any clogs or obstructions.
  4. Run water through the disposal to ensure it is draining properly.
  5. Check the s-trap, which is the curved portion of the drain pipe under the sink.
  6. Make sure it is not clogged or blocked.

Once you have checked these components, reconnect the dishwasher to the power source and run a cycle to see if the E24 error code persists.

6. Check the Drain Pump

If all the previous steps have not resolved the Bosch dishwasher E24 error code, it is recommended to check the drain pump for any issues.

Here’s what you need to do:

  1. Disconnect the dishwasher from the power source.
  2. Remove the dishwasher from its installation to access the back panel.
  3. Remove the drain pump and check for any obstructions or damage.
  4. Clean or replace the drain pump as needed.
  5. Reinstall the dishwasher and reconnect it to the power source.

If the E24 error code still persists after checking the drain pump, it is recommended to seek professional assistance.

To drain water from a Bosch dishwasher displaying the E24 error, begin by turning off the dishwasher and unplugging it from the power source for safety.

Next, locate the drainage hose underneath the sink and detach it from the dishwasher connection point.

Place the end of the hose into a shallow container positioned below the connection to catch the water.

Gently lift the hose to allow gravity to assist in draining the water from the dishwasher into the container.

Once the water stops flowing, reattach the hose securely and proceed with troubleshooting the E24 error by inspecting for blockages or clogs in the filter, drain pump, or drainage system.
