Owning a Bosch dishwasher is a testament to the brand’s commitment to quality and innovation in home appliances.

Bosch dishwashers are known for their efficient cleaning performance and reliability. However, even the most advanced machines can encounter occasional issues.

One such problem that users may come across is the dreaded E23 error code.

If you’ve ever seen the E23 error displayed on your Bosch dishwasher’s control panel, you might wonder what it means and how to resolve it.

Fear not!

This troubleshooting guide is here to help you understand the E23 error and provide step-by-step instructions on how to troubleshoot and fix the issue.

How to Fix Bosch Dishwasher Error E23

Bosch dishwasher error E23 is an indication of a drainage issue within the dishwasher. When this error code appears on the dishwasher’s display panel, it means that the appliance is having trouble draining water properly during its cycle. As a result, the dishwasher is unable to complete the wash cycle, and it stops to prevent any potential water leakage or damage.

The drainage system in a dishwasher is crucial for removing wastewater from the unit after each wash.

If the water does not drain correctly, it can lead to standing water at the bottom of the dishwasher, which may cause the E23 error.

Before you begin:

Safety First: Always prioritize safety. Turn off the dishwasher and unplug it from the power outlet before attempting any troubleshooting.

Check the Warranty: If your Bosch dishwasher is still under warranty, contact Bosch customer service or your dealer for assistance. Opening the dishwasher or attempting repairs yourself could void the warranty.

How to Fix Bosch Dishwasher Error E23

Step 1: Inspect the Drain Hose

  • Locate the dishwasher’s drain hose. It is usually connected to the sink’s drain or garbage disposal unit.
  • Ensure the drain hose is not kinked, bent, or damaged. Straighten any kinks gently and check for any visible leaks.

Step 2: Check for Clogs

  • Remove any large debris or food particles from the dishwasher’s filter and spray arm. Clean them thoroughly under running water.
  • Inspect the drain filter located at the bottom of the dishwasher. Lift it out and clean any debris accumulated inside.
  • Use a pipe cleaner or a long, flexible brush to check for and remove any clogs in the drain hose or the sink’s drain.

Step 3: Verify the Garbage Disposal

  • If your dishwasher is connected to a garbage disposal unit, check if it is working correctly. Run the disposal to ensure it is clear of any obstructions.
  • Ensure that the knockout plug inside the disposal unit has been removed.
  • If it’s still in place, this can cause drainage issues. Refer to the garbage disposal’s manual for instructions on how to remove the plug.

Step 4: Check the Drain Pump

  • The drain pump is responsible for removing water from the dishwasher during the drain cycle. It may be clogged or faulty, causing the E23 error.
  • Access the drain pump by removing the dishwasher’s lower front panel. Refer to the user manual for specific instructions on how to do this.
  • Once you have access to the drain pump, check for any debris or foreign objects that may be obstructing its operation
  • If the drain pump looks damaged or is making unusual noises, it may need to be replaced. Contact Bosch customer service or a professional technician for further assistance.
