AEG dishwasher not completing a cycle: safe checks before service

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

1. Check 1

   Before cancelling the programme, record the exact display code or flashing-light pattern, whether the door is locked or latched, whether water remains in the tub, and where in the cycle the stop occurred.

   Expected result: The dishwasher shows a named code or repeatable light pattern, leaves standing water, or simply remains on an active programme without a code.

   Next step: Keep the record for the exact model manual or service visit and continue only with the matching external branch below.

   Why this matters

   Why: The observation separates a documented drain or control path from a stuck programme; a missing code does not prove a component failure.

2. Check 2

   Check that the door closes fully with an audible latch and that Delay Start or another previous programme is not still active; do not force the door or guess a button combination.

   Expected result: The door does not latch, a delay countdown is active, or the controls remain on the previous programme; alternatively the door latches and no delay is shown.

   Next step: Use the exact model manual to cancel the delay or programme. If the door cannot latch or the programme remains stuck, arrange service rather than bending hardware or bypassing the latch.

   Why this matters

   Why: AEG identifies door closure and prior programme/delay settings as reasons a cycle may not start or a new cycle may not be selectable.

3. Check 3

   If the dishwasher is safely idle and the model's controls match the AEG support guidance, hold the documented RESET/CANCEL control to abort the active programme and allow the appliance to drain; use the exact model manual if the controls differ.

   Expected result: The appliance returns to programme selection and drains, or it remains stuck, does not drain, or immediately shows a fault again.

   Next step: If reset fails or the error returns, stop repeating resets and move to the model-specific service path; never use a reset to conceal a leak or standing-water hazard.

   Why this matters

   Why: A reset can clear a previously active programme, but it does not establish or repair an underlying drain, control, or electronic fault.

4. Check 4

   Disconnect the dishwasher from power, then inspect and clean only the accessible interior filters and sump; if water remains, check the visible drain hose and sink connection for kinks or an obstruction without dismantling the pump.

   Expected result: Filters or the sump are clogged, the drain hose is kinked/blocked, or the accessible drain path is clear but water remains.

   Next step: Refit filters correctly and use the exact model's documented drain test. If water remains or the path is inaccessible, leave the appliance off and request service.

   Why this matters

   Why: AEG associates i20-family drainage symptoms with filter/sump, hose, and sink-spigot conditions. A clear external path does not prove the internal pump or wiring is sound.

5. Check 5

   Stop user troubleshooting if the programme stops on every cycle, a code returns after the documented checks, controls stay unresponsive, water leaks, or the appliance shows a power or electrical concern.

   Expected result: The failure is repeatable or accompanied by a leak, repeated code, burning smell, damaged cord, or unresponsive controls.

   Next step: Keep the dishwasher switched off, close the water supply if there is active leakage and it is safe to do so, and arrange an authorised service visit. Do not open the cabinet or perform live electrical tests.

   Why this matters

   Why: AEG treats recurring error conditions and persistent programme failure as requiring professional diagnosis; the symptom alone cannot identify the failed internal component.
