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 fault in the wash-arm diverter circuit.
  • A problem with the diverter or its control-board circuit; the code does not distinguish between them.
  • A temporary control issue that may clear after a power reset.
  • On some models or in some regions, a different code may be used for the same fault.

What to try

Check for blocked spray arms

Easy
  1. Switch the dishwasher off and wait until it is safe to open the door.
  2. Check whether dishes or utensils are physically blocking the spray arms.
  3. Rearrange any items that prevent the arms from moving freely.
  4. If E05 remains, follow the power-reset steps or contact Bosch support.

Reset the dishwasher’s power

Easy
  1. Switch off power to the dishwasher at the circuit breaker.
  2. Leave the power off for 30 seconds.
  3. Restore power and check whether the error remains.
  4. If E05 persists or returns, contact Bosch support or a qualified technician.

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

Arrange service if the error persists

Professional

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

  1. Find the dishwasher’s full model number (E-Nr), usually shown on the appliance label.
  2. Check the Bosch support information for your model and country, since code meanings can vary.
  3. Contact Bosch support or a qualified appliance technician if E05 remains or returns.
  4. If you are in the United States, Bosch lists 1-800-944-2904; have the E-Nr ready.

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.
