Does this guide apply to your appliance?

Match the brand, device type and complete display code. The same code can mean something different on another product family or market; a series name does not confirm every model in that series.

No exact model number is recorded here. Confirm the code in your appliance manual before following a check.

Likely causes

  • A blocked filter or drain path
  • A kinked or clogged drain hose
  • A loose or blocked pump cover
  • A blocked air gap, if fitted
  • A dishwasher-inlet knockout plug left in a newly installed garbage disposal

What to try

Check the accessible drain path

Easy
  1. Switch off power to the dishwasher.
  2. Check accessible sections of the drain hose for kinks or visible blockage.
  3. If your installation has an air gap, check it for blockage.
  4. If the dishwasher is connected to a newly installed garbage disposal, verify that the dishwasher-inlet knockout plug was removed.
  5. Use your model’s manual for any additional checks; if the cause is not clear, contact a qualified servicer.

This step is marked caution. Stop if you are not qualified to continue.

Clean the filter and inspect the pump cover only as directed

Moderate
  1. Keep the dishwasher’s power off.
  2. Consult the manual for your exact model before removing or cleaning the filter or inspecting the pump cover.
  3. Follow only the manual’s instructions, taking care around debris that may be sharp.
  4. If the pump cover appears damaged or blocked, or E24 remains afterward, stop and contact a qualified servicer.

This step is marked caution. Stop if you are not qualified to continue.

Contact Bosch or an authorized servicer

Professional

This is a service referral, not a do-it-yourself repair procedure.

  1. Arrange service if E24 remains after the checks approved by your model’s manual.
  2. Request qualified service if the issue may involve the pump, an internal blockage, or work beyond those checks.
  3. In the U.S., contact Bosch at 1-800-944-2904 or use its dishwasher support page.

This step is marked professional. Stop if you are not qualified to continue.

The code returned or the check did not help?

Avoid repeated resets and do not select a replacement part from the code alone. Record the exact code, full model number, when it appeared, and the checks you tried with their results. Share these details with the manufacturer or service technician.

Disconnecting power does not establish that internal components are safe to touch. This guide does not authorize opening electrical components or bypassing safety devices.
