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.

Model and family references in this record:

iQ100iQ300iQ500iQ700SN Series

Likely causes

  • Circulation pump (heat pump) motor winding failure or low electrical resistance
  • Wiring harness or connector fault between the control module and circulation pump
  • Foreign debris obstructing the circulation pump impeller or sump
  • Main electronic control board malfunction

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.
