If you own a Bosch dishwasher, you may have encountered the e22 error code at some point. This error code can be frustrating, as it prevents your dishwasher from functioning properly.

However, with a little bit of knowledge and troubleshooting, you can easily fix the e22 error code and get your dishwasher back up and running.

In this article, we will guide you through the process of understanding and resolving the Bosch e22 error code.

Understanding the Bosch e22 Error Code

The Bosch e22 error code is a crucial signal of a problem. It serves as a clear indicator that the appliance is struggling to effectively drain the water, leading to the emergence of this error code. There are several potential culprits that can contribute to the e22 error code, but the most common are: clogged filter, malfunctioning pump, blocked drain hose and some other issues such as problems with a sensor or even external parts.

How to Solve the Problem Yourself?

1. Clean the Filter

Use the below step-by-step instructions to clean the filter.

  1. Turn Off the Dishwasher: Before you begin, make sure the dishwasher is powered off to ensure safety.
  2. Remove the Bottom Rack: Open the dishwasher and carefully slide out the bottom rack. This will provide you with access to the filter.
  3. Locate the Filter Assembly: In the bottom of the dishwasher’s interior, you’ll find the filter assembly. The filter is typically comprised of multiple components, including the main filter, a fine filter, and a coarse filter.
  4. Remove the Filter Components: Depending on your dishwasher model, the filter components may be twist-locked or clipped into place. Carefully remove these components, starting with the main filter.
  5. Rinse the Filter Components: Take the filter components to a sink or an area with running water. Rinse each component under the tap to remove any accumulated food particles and debris. You may use a soft brush or your fingers to help dislodge stubborn residue.
  6. Inspect and Clean the Filter Housing: While the filter components are removed, take a moment to inspect the filter housing within the dishwasher for any debris or blockages. Use a cloth or paper towel to clean the inside of the filter housing.
  7. Reassemble the Filter: Once the filter components are clean and the housing is clear, reassemble the filter by securing each component back into its place, following the manufacturer’s instructions for your specific dishwasher model.
  8. Return the Bottom Rack: Carefully slide the bottom rack back into the dishwasher.
  9. Power On the Dishwasher: Turn the dishwasher back on and run a test cycle to see if the e22 error code has been resolved.

While a clogged filter is the most common cause of the e22 error code, there are other factors that can contribute to this issue. These include a malfunctioning drain pump, a blocked drain hose, or an obstructed impeller.

So if after cleaning the filter, your dishwasher still displays an error, then try the following steps:

2. Check the Drain Pump

Locate the drain pump in your dishwasher and ensure it’s working properly. Listen for any unusual noises or vibrations. If the pump is malfunctioning or not running at all, it may need to be replaced. A faulty drain pump can lead to drainage issues and trigger the e22 error code.

3. Inspect the Drain Hose

Examine the drain hose for any kinks, bends, or blockages that may hinder proper water drainage. Straighten out any kinks and remove any obstructions that you find. A clear and unobstructed drain hose is crucial for effective water disposal.

4. Clear the Impeller

The impeller is responsible for pushing water through the dishwasher’s drain system. If it’s clogged or obstructed, it can contribute to the e22 error code. Carefully access the impeller and ensure it spins freely. Clean any debris or blockages that may affect its operation. A proper impeller function is essential for efficient drainage.

5. Reset the Error Code

In some instances, a simple reset may clear the e22 error code. Turn off the dishwasher and unplug it from the power source. Wait for a few minutes to allow the appliance to fully power down. Plug it back in and turn it on. Run a test cycle to check if the error code has been reset and if the dishwasher functions correctly.

By following the steps outlined in this article, you can easily resolve the dishwasher error code and get your dishwasher back in working order. If you’re still unable to fix the issue, it’s always a good idea to consult with a professional appliance repair service.
