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

  • Water has entered the appliance base, possibly because of a leak; the code alone does not reveal the leak’s source.
  • Excess foam may contribute to the problem.
  • A blocked spray arm or items preventing a spray arm from turning freely may contribute.
  • The appliance may not be level.

What to try

Make the appliance safe and check whether service is needed

Easy
  1. Close the dishwasher’s water tap.
  2. If safe and accessible, switch off and unplug the dishwasher.
  3. Look for visible leaking without removing panels or opening the appliance.
  4. If you see a leak, the pump continues running, or i30 returns, keep the water supply off and contact an authorised technician.

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

Check loading, level, and accessible parts

Easy
  1. With the dishwasher off, check whether it appears level.
  2. Rearrange dishes so both spray arms can turn freely.
  3. Remove and clean only the accessible filters and spray arms, following the appliance manual.
  4. Inspect the accessible sump area and door gasket for visible debris, then refit any removable parts correctly.
  5. Do not use the dishwasher if i30 remains or returns; arrange technician service.

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

Check for excess foam

Easy
  1. With the appliance off, look for visible excess foam, if this can be checked safely.
  2. Do not add detergent or run another cycle while i30 is showing.
  3. If foam is present, follow AEG’s guidance for excess foam and your model’s manual.
  4. If the code returns or there are signs of leaking, keep the water supply off and contact a technician.

This step is marked caution. 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.
