AEG Dishwasher Not Working: Separate Power, Start, and Cycle Faults

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

1. Check 1

   Look at the control panel and note whether any display, indicator, or response appears when the normal On/Off control is pressed; do not keep pressing if there is smoke, heat, a burning odor, or water near electrical parts.

   Expected result: The panel is completely dark, the panel lights but the programme will not begin, a programme indicator flashes, or the appliance stops after starting.

   Next step: Follow the matching branch below rather than resetting every symptom in the same way. For a safety warning, stop using the dishwasher and arrange qualified service.

   Why this matters

   Why: A dark panel points first to supply or power-control questions. A lit but idle panel is more consistent with programme selection, door detection, Delay Start, a previous programme, DEMO mode, or a model-specific control state. A flashing indicator or mid-cycle stop can indicate a condition or fault that needs the manual.

2. Check 2

   If the panel is dark, confirm that the plug is inserted and the wall switch is on; if the socket is cool, dry, and safe, check it with a small known-working device rather than opening the socket or dishwasher.

   Expected result: The test device also has no power, the socket works but the AEG panel remains dark, or the dishwasher plug/cord/socket is hot, damaged, wet, or loose.

   Next step: If the socket is dead, stop and contact a local electrician. If the dishwasher remains dark with a working socket, request an authorised service visit. Do not use a damaged connection or continue if it is unsafe to touch.

   Why this matters

   Why: A second device that also fails makes the electrical connection, fuse, breaker, or RCD more likely. A working socket with a dark dishwasher points more toward the appliance, while heat, damage, moisture, or looseness is a safety condition rather than a normal no-start.

3. Check 3

   Check the visible breaker or RCD status only from a safe, dry position and note whether it has opened; reset it at most once only when there is no smoke, heat, water, damage, or active fault indication.

   Expected result: The breaker/RCD stays on after a single reset, opens again immediately, or will not remain on; the dishwasher may be unplugged or still connected.

   Next step: For a repeated or non-resetting trip, stop and call an electrician or authorised service professional; do not increase a fuse/breaker rating, bypass the RCD, or test inside the panel. If power returns safely, continue with the lit-panel checks.

   Why this matters

   Why: A protective device that opens again can indicate an appliance or electrical fault and should not be defeated by repeated resets. A reset that restores power does not prove the dishwasher is healthy.

4. Check 4

   If the display is on, select a programme before closing the door, then close the door normally and confirm that it latches; do not slam or force it.

   Expected result: The cycle starts after a programme is selected and the door clicks shut, or the door will not latch, the appliance gives no start response, or the door-status indicator remains.

   Next step: Rearrange only items visibly preventing closure and use the exact manual for approved alignment checks. If the door still will not latch or the programme will not start, stop and request service rather than bending the housing or dismantling the latch.

   Why this matters

   Why: AEG dishwashers are designed to start only after a programme is selected and the door is detected as fully closed. A door that will not latch can reflect loading, alignment, level, or latch trouble rather than a dead control.

5. Check 5

   Check the display and controls for Delay Start, a previous programme, RESET/CANCEL, or a DEMO indication such as `d:on`; use only the reset sequence documented for the exact model.

   Expected result: Delay Start is active, the controls remain on an old programme, the model's reset clears the selection, or the display shows DEMO mode and the start animation ends without filling.

   Next step: Cancel the delay or old programme with the matching manual procedure. If DEMO mode is displayed, follow the exact AEG deactivation instructions for that model. Do not guess a button combination from another dishwasher.

   Why this matters

   Why: A stored delay or previous programme can make a working dishwasher appear unresponsive. AEG says DEMO mode can display functions without actually connecting to water or drain, and reset/button combinations vary by model.

6. Check 6

   If a programme indicator is flashing or the cycle refuses to start, switch the dishwasher off and check only the user-accessible door, filters, spray arms, salt-container cap, racks, and detergent loading against the exact manual.

   Expected result: A filter is dirty or not seated, a spray arm is blocked, the salt cap is loose, an item obstructs the door or spray arm, or these checks are normal but the indicator still flashes.

   Next step: Disconnect the plug before cleaning filters or reaching into the tub, refit parts exactly as shown, and do not run the dishwasher with a missing or loose filter. If the light remains, record it and request an authorised service assessment.

   Why this matters

   Why: AEG lists clean, correctly installed filters, freely moving spray arms, a tight salt cap, correct loading, and correct detergent as pre-start checks. A persistent flashing indicator after these conditions are correct needs the model guide or service.

7. Check 7

   For a cycle that starts and then stops, record the display, indicator pattern, water-inlet or drain symptoms, and whether the door remains closed; do not repeatedly start cycles to reproduce the failure.

   Expected result: The dishwasher shows an error, does not fill, does not drain, stops and restarts, or returns to programme selection after a reset; there may be standing water or a leak.

   Next step: Note the complete error exactly and consult the matching manual or AEG support. If water is leaking, standing dirty water remains, the appliance trips protection, or the fault repeats, leave it off and arrange qualified service; do not dismantle hoses or pumps.

   Why this matters

   Why: These patterns can involve water intake, drainage, door sensing, pump operation, a protective stop, or an internal electronics fault. The visible symptom does not identify a replaceable part.

8. Check 8

   Prepare the complete model number/PNC, serial number, exact indicator or error, power status, programme selected, door behavior, water symptoms, and checks already performed before contacting AEG.

   Expected result: The problem is repeatable with one programme, occurs immediately on power-up, follows a breaker/RCD trip, or cannot be reproduced after a safe reset.

   Next step: Request an authorised AEG service visit when the safe checks do not restore operation. Do not order a latch, pump, heater, control board, or other part from the symptom alone.

   Why this matters

   Why: Model and timing information allow AEG or a technician to distinguish a supply issue, user-selectable state, installation condition, or internal fault without asking the homeowner to open the appliance.
