AEG Dishwasher Error Displayed: Identify the Code Before You Reset It

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Before clearing the display, record the complete error code, the number of beeps or LED flashes, the programme stage, and whether the dishwasher is filling, draining, washing, heating, or running its pump continuously. Photograph the panel and the rating plate showing the PNC and serial number.

   Expected result: A full code is visible; only a beep or flash pattern is visible; the code is partly obscured; or several codes appear together.

   Next step: If the code is readable, follow the matching branch below. If it is not readable, stop guessing and use the PNC to retrieve the exact AEG manual or support article. If multiple codes return, arrange service rather than treating one code as definitive.

   Stop if: Stop using the dishwasher if water is leaking, the pump runs continuously with an i30 pattern, there is a burning smell, exposed wiring, or the appliance trips the electrical supply.

   Why this matters

   Why: The code or pattern selects the correct AEG troubleshooting family. A partial or mixed display cannot safely identify a component, and a repeated or multiple-code event needs the exact model information for service.

2. Check 2

   For i10, i11, AL5, C1, or F1-style inlet indications, with the appliance safe to inspect, confirm that the water tap is fully open, the household supply flows, and the inlet hose is not kinked, twisted, or damaged. Close the tap before checking the small inlet-hose filter, and use the manual for its removal and cleaning instructions.

   Expected result: The tap is closed or has weak supply; another water-using appliance is reducing flow; the inlet hose is kinked or damaged; the filter has scale or debris; or the inlet path appears clear.

   Next step: If the tap, hose, or filter is the clear restriction, correct only that accessible issue as described by AEG and run a suitable programme once. If water does not flow at the household tap, contact the water supplier.

   Stop if: If the inlet path is clear but the code returns, stop repeated cycles and arrange an approved service visit; do not replace the inlet valve without model-specific confirmation.

   Why this matters

   Why: AEG associates this family with insufficient water entering the dishwasher. A visible restriction is more likely than an internal valve failure, while a damaged hose requires an engineer and a clear path that still produces the code needs service diagnosis.

3. Check 3

   For i20, C2, F2, or AL6-style drainage indications, check the sink spigot, dishwasher filters, sump, and the accessible drain hose. Look for a clogged connection, debris, a kink or twist, damage, or a recently moved dishwasher whose sink-trap blanking plug was never removed.

   Expected result: The sink connection or filter/sump is blocked; the drain hose is kinked or incorrectly routed; the blanking plug remains in the sink trap; or the drain path is clear but the code persists.

   Next step: Correct a visible blockage or installation error only when it can be done safely and according to the manual, then reconnect and run a suitable cycle. If the code returns or standing water remains, keep the appliance off and arrange service.

   Stop if: Do not reach into standing water, dismantle the pump, or continue a cycle when water cannot be controlled.

   Why this matters

   Why: AEG defines this family as a drainage problem. A blockage or installation issue can explain the code without proving a failed drain pump; persistence after the accessible path is clear requires a technician.

4. Check 4

   For an i30 pattern, or three beeps/flashes with constant low pump noise or visible leaking, close the water tap immediately. Check only the installation level, loading that could deflect a spray jet, clean filters/spray arms/sump, and the door gasket; then leave the dishwasher disconnected with the tap closed if the manual and AEG guidance permit an overnight dry-out.

   Expected result: There is visible water, a wet base, a dirty gasket or sump, foam, a blocked spray arm, a large item deflecting water, or no visible cause and the i30 pattern returns.

   Next step: Keep the tap closed and do not run the appliance until the source is addressed. If the code returns after the permitted dry-out and accessible checks, book an authorised repair and provide the code, leak timing, and observations.

   Stop if: Do not tip the dishwasher, remove panels, or keep testing it with the water supply open when i30 or a leak recurs.

   Why this matters

   Why: AEG says i30 may indicate water collecting in the base and an anti-flood response. Loading, foam, or accessible contamination can contribute, but a recurring code means the underlying internal leak has not been established or repaired.

5. Check 5

   For i40/i43/i44 or i50-family indications, use the exact AEG page for the code, disconnect mains power only as directed, and perform only the stated reset and accessible filter/sump cleaning. For i60-family, iF0-family, or an unlisted code, go directly to the AEG manual or model support search instead of borrowing a procedure from another family.

   Expected result: The dishwasher completes a cycle after the supported reset and cleaning; the same code returns; foam or debris was present; or the code is i60/iF0-family or not listed.

   Next step: If the cycle completes normally, monitor it and keep the code record. If the code returns, or the code is unlisted, stop DIY diagnosis and arrange authorised service with the PNC, serial number, and display evidence.

   Stop if: Do not bypass a sensor, heater, pump protection, door interlock, or control, and do not test internal electrical parts unless qualified and the model manual explicitly supports that procedure.

   Why this matters

   Why: AEG links i40-family codes with pressure-sensor or water-level control and i50-family codes with wash motor/pump malfunction. A reset or clean sump can clear a temporary condition, but it cannot prove the sensor, pump, heater, or control board is sound.
