Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not repeatedly reset, tip, or move the appliance to clear a leak code.
- Do not open drain or pump areas while the appliance is powered.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Excess foam allowing water to reach the base area
- A large item blocking the spray arm or deflecting water toward the door
- Water entering the base from a possible internal leak
- Door gasket visibly dirty or damaged
Basic checks
- Stop the programme and close the dishwasher water tap if it is safe to reach.
- Switch off the dishwasher and disconnect power only when the plug and surrounding floor are dry; otherwise use a safe isolator and keep clear of the wet area.
- Observe the floor and cabinet edges from outside without pulling or tipping the dishwasher; if water is visible, keep clear and arrange qualified help.
- If there is no external water and the tub can be opened safely, check only whether a large item blocks the spray arm or the visible door gasket is dirty; do not reach into standing water.
Reset or retry steps
- Do not reset or restart the dishwasher while i30 is active or until the source of water in the base has been professionally assessed.
When to call a technician
- Contact AEG service for i30 when the drain pump runs continuously, the code returns, or water may be present in the base.
- Keep power off and seek urgent qualified help if water is near an outlet, cord, plug, or other electrical connection.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
