AEG dishwashers are known for their reliability and advanced features, but like all appliances, they can occasionally display error codes. These codes, shown on the digital display, help you quickly identify the problem. This complete list covers the most common AEG dishwasher error codes, their meanings, possible causes, and how to fix them. For a broader overview of AEG appliance repair in Spain, see our complete guide to AEG appliance repair.

Understanding AEG Dishwasher Error Codes

AEG dishwashers use a standardized set of error codes. They typically appear as an “i” followed by a number (e.g., i10, i20) or as a combination of flashing lights. The exact interpretation can vary slightly by model, but the following list applies to most AEG dishwashers sold in Spain since 2010.

How to Read the Error Code

When an error occurs, the dishwasher will stop its cycle and display a code. Some models show the code on the digital screen; others use flashing LEDs. Refer to your user manual for the exact display method. If you don’t have the manual, you can often find it on the AEG website by entering your model number.

Common AEG Dishwasher Error Codes

i10 – No Water Inlet

Meaning: The dishwasher is not filling with water. The machine detects that no water has entered within a certain time.

Possible causes:

  • Water supply tap is closed or turned off.
  • Inlet hose is kinked or blocked.
  • Water inlet valve is faulty.
  • Low water pressure in your home (below 0.5 bar).

How to fix:

  1. Check that the water supply tap is fully open.
  2. Inspect the inlet hose for kinks or bends. Straighten it if needed.
  3. Turn off the water, disconnect the hose, and check for blockages. Clean the inlet filter (a small mesh screen inside the hose connection).
  4. If the problem persists, the water inlet valve may be defective. Replacing it typically costs between €30 and €60 for the part, plus labor if you hire a technician. In Spain, a repair visit can range from €60 to €120.

For more on water-related issues, see our article on AEG drain problems (though focused on washing machines, the principles are similar).

i20 – Drainage Problem

Meaning: The dishwasher is not draining water. The machine detects that water remains in the sump after the drain cycle.

Possible causes:

  • Drain hose is kinked or blocked.
  • Kitchen sink drain is clogged (if connected to the same pipe).
  • Drain pump is faulty or blocked by debris.
  • Blockage in the filter system.

How to fix:

  1. Check the drain hose for kinks and ensure it is not inserted too far into the standpipe (no more than 15 cm).
  2. Clean the dishwasher filters (bottom of the tub). Remove any food particles or debris.
  3. Check the drain pump for obstructions. You may need to remove the lower spray arm and cover to access the pump. Use a flashlight to look for foreign objects (e.g., broken glass, bones). Remove carefully.
  4. If the pump is jammed or not running, it may need replacement. A new drain pump costs around €40–€80.

i30 – Anti-Flood System Activated

Meaning: The anti-flood device has detected water in the base tray. This is a safety feature to prevent water leaks.

Possible causes:

  • Small leak from a hose or seal.
  • Overfilling due to a faulty water inlet valve.
  • Condensation or spillage during loading.

How to fix:

  1. Turn off the dishwasher and unplug it.
  2. Check for visible leaks under the appliance. If you find water, dry the base tray thoroughly.
  3. Inspect all hose connections and tighten if loose.
  4. If the code reappears, there may be a persistent leak. Call a technician. Repair costs vary depending on the source of the leak.

i50 – Turbidity Sensor Failure

Meaning: The turbidity sensor (which measures water clarity) is faulty or disconnected.

Possible causes:

  • Sensor is dirty or covered with grease.
  • Electrical connection issue.
  • Sensor failure.

How to fix:

  1. Clean the sensor (located near the filter area) with a soft cloth and mild detergent.
  2. Check the wiring harness for loose or damaged wiring.
  3. If cleaning does not work, the sensor may need replacement. Part cost: €25–€50.

i60 – Heating Element Fault

Meaning: The dishwasher is not heating the water. The cycle may run but dishes remain cold.

Possible causes:

  • Faulty heating element.
  • Thermostat or NTC sensor failure.
  • Wiring issue.

How to fix:

  1. Measure the resistance of the heating element (located at the bottom of the tub) with a multimeter. A typical reading is 20–30 ohms. If infinite, the element is open and needs replacement.
  2. Check the NTC sensor (thermistor) for correct resistance at room temperature (around 10–20 kΩ).
  3. Replace faulty parts. Heating element cost: €35–€70.

i70 – Water Level Sensor Fault

Meaning: The pressure switch (water level sensor) is not functioning correctly.

Possible causes:

  • Blocked air chamber (tube from the sump to the pressure switch).
  • Faulty pressure switch.
  • Wiring issue.

How to fix:

  1. Check the air chamber tube for blockages. Clean with a pipe cleaner or compressed air.
  2. Test the pressure switch with a multimeter. It should change state when air is applied.
  3. Replace if defective. Part cost: €20–€40.

i80 – Circulation Pump Failure

Meaning: The circulation pump (wash pump) is not operating.

Possible causes:

  • Pump motor burned out.
  • Impeller blocked.
  • Electrical fault.

How to fix:

  1. Listen for a humming sound. If you hear a hum but no movement, the impeller may be stuck. Remove the pump and clean it.
  2. Check the pump motor windings with a multimeter. If open, replace the pump.
  3. Circulation pump cost: €50–€100.

Less Common Error Codes

i00 – No Error

This may appear briefly during startup. Not a fault.

i90 – Electronic Control Board Fault

Meaning: The main control board has detected a fault.

Possible causes: Power surge, component failure, or software glitch.

How to fix: Try resetting the appliance by unplugging for 10 minutes. If the code returns, the control board may need replacement. Cost: €100–€200 plus labor.

iA1 – Communication Error

Meaning: Communication between the control board and the user interface is disrupted.

Possible causes: Loose or damaged wiring, faulty display board.

How to fix: Check connections between boards. Replace the display board if needed.

General Troubleshooting Tips

Before calling a technician, try these steps:

  • Reset the dishwasher: Unplug it for 10–15 minutes, then plug back in. This clears temporary glitches.
  • Check the water supply and drain hoses for obvious issues.
  • Clean the filters and spray arms. A clogged filter can cause many errors.
  • Consult the manual for model-specific codes. Manuals are available on the AEG Spain website.

If the error persists, it’s best to contact a professional. In Spain, authorized AEG service centers offer fixed-rate repairs. For example, Servicio Técnico Oficial AEG in Madrid charges €79 for a diagnostic visit (including first hour of labor).

Preventive Maintenance

Regular maintenance can prevent many errors. Here are some tips:

  • Clean the filters after every few cycles.
  • Use dishwasher cleaner (e.g., Finish Machine Cleaner, €5–€7 at Carrefour or El Corte Inglés) monthly to remove grease and scale.
  • Check the inlet hose for kinks and ensure the tap is fully open.
  • Run a hot water cycle (60°C or higher) occasionally to sanitize.
  • Inspect the door seal for cracks or debris.

When to Call a Professional

Some repairs require specialized tools and knowledge. If you are not comfortable working with electrical components or plumbing, call a certified technician. In Spain, you can find local AEG repair services through the official AEG website or platforms like Habitissimo. Typical costs: diagnosis €60–€90, labor €40–€70 per hour, plus parts.
