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 with the Zeolite (Crystal Dry) drying-chamber heater, as Bosch describes E10 on applicable models.
  • The code may have a different meaning on another model or market; the code alone cannot confirm the fault without checking the dishwasher’s E-Nr and manual.

What to try

Confirm the code and perform a power reset

Easy
  1. Switch the dishwasher off at the circuit breaker.
  2. Leave power off for 30 seconds.
  3. Restore power and check whether E10 clears.
  4. Find the dishwasher’s E-Nr and consult its manual to confirm the code’s meaning for your exact model.

Arrange qualified service if E10 returns

Professional

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

  1. Stop troubleshooting the dishwasher internally.
  2. Contact Bosch or a qualified dishwasher technician and provide the E-Nr and the E10 code.
  3. Do not remove panels or attempt to repair the heater or other internal parts.

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.
