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

  • Failed heating element due to burnout.
  • Corroded heater terminals caused by moisture or mineral deposits.
  • Control board relay failure supplying power to the heating element.

What to try

Stop operation and arrange manufacturer service

Professional

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

  1. Switch the dishwasher off and close the water supply tap if it is safely accessible.
  2. Do not open panels or replace components based on the display code.
  3. Record the exact code and full model number, and arrange service with the manufacturer or a qualified technician.

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.
