AEG washer dryer displays an error: identify the code and troubleshoot safely

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

1. Check 1

   With the appliance stopped, record every character on the display and note whether the Start/Pause light is flashing, the appliance is beeping, or the code returns after a restart.

   Expected result: Only the Start/Pause light is flashing and the display shows the end of a cycle or no fault code.

   Next step: Press Start/Pause once to resume if the door is safely closed; if a definite code is present or the light keeps flashing, continue with the matching code branch.

   Why this matters

   Why: The cycle may be paused or complete rather than failed; AEG notes that a flashing Start/Pause light can follow an accidental pause and that an end-of-cycle door delay is a safety feature.

2. Check 2

   If the code is E10, E11, or C1, check that the water tap is open, inspect the inlet hose for a kink, and clean only the accessible inlet filter using the model manual's procedure.

   Expected result: Water flow is weak, the inlet filter is visibly dirty, or the hose is kinked; alternatively, water supply looks normal but the code remains.

   Next step: Correct the hose or clean the filter, then run a short programme. If the code returns, record it and request service rather than opening the appliance.

   Why this matters

   Why: A restriction can explain a water-intake fault; if the supply and hose are normal but the code persists, the machine may also be detecting a drain or internal supply problem.

3. Check 3

   If the code is E20, E21, or C2, inspect the visible drain hose for a kink and confirm that its installation position agrees with the model manual; with the appliance unplugged and the water cool, clean the drain pump filter if your model has one.

   Expected result: The hose is kinked, the filter contains lint or an object, or water drains normally after the accessible blockage is cleared.

   Next step: Refit the filter firmly, check for leaks, and run a short rinse or drain test. Stop if water escapes or the code returns.

   Why this matters

   Why: A restricted drain path can cause a pumping fault. If the filter and hose are clear but the pump still cannot drain or makes an unusual noise, a pump or concealed blockage needs professional diagnosis.

4. Check 4

   If the code is E40, check that the door is fully closed, remove any garment caught between the seal and glass, and make sure the drum is not overloaded; inspect the mechanical child lock only as described by the model manual.

   Expected result: The door closes with a click and the code clears after a smaller load, or the code remains despite a clear seal and correctly closed door.

   Next step: Retry once after correcting the load. If E40 returns, leave the lock and wiring untouched and arrange an authorised repair.

   Why this matters

   Why: A trapped garment, overload, or engaged child lock can prevent the door from being accepted. Persistence with a clear door points to the door-lock system rather than a loading error.

5. Check 5

   If the code is E30 or C3, or EF0, EFo, or EF3, inspect the inlet-hose connections, the door seal, the dispenser area, and the floor around the appliance for fresh water; do not remove panels.

   Expected result: There is fresh water, a damaged seal or hose, a loose filter, or the machine keeps pumping water; alternatively, no leak is visible and the code returns.

   Next step: Turn off the water supply and unplug the machine if safe to do so; do not use it until the leak is repaired. If no external cause is visible but the code persists, request service.

   Why this matters

   Why: AEG associates E30/C3 with water in or under the appliance and EF0/EFo/EF3 with water-safety conditions that can involve leakage or excess foam. A visible leak is a safety fault, not a normal reset situation.

6. Check 6

   If the display shows EH0, EH1, EH2, or EH3, check the wall socket with another small appliance and verify that the washer dryer is not connected through an extension lead; do not open the plug, socket, or appliance.

   Expected result: The socket also fails, or the washer dryer reports the power code again from a working socket.

   Next step: Stop using the appliance and get electrical or authorised appliance help as appropriate. Never bypass a protective device or continue testing a suspect supply.

   Why this matters

   Why: A failed socket points to the household supply and should be handled by an electrician; a working socket with a recurring code points to an appliance power or control fault.

7. Check 7

   If the display shows E50, E59, C9, or F9, or E90 through E94, switch the appliance off and note the exact code; for an electronic code, one reset after the appliance has been safely unplugged may be attempted, but do not repeat resets to keep it running.

   Expected result: The code disappears once but returns, or it remains immediately after the reset; the appliance also smells hot, trips power, or behaves abnormally.

   Next step: Leave the appliance unplugged, turn off its water tap, and arrange an authorised service visit. Do not test or replace motor, heater, or electronic parts yourself.

   Why this matters

   Why: AEG identifies E50/E59/C9/F9 as motor faults and E90-E94 as electronic configuration or communication faults. A returning code is evidence that the underlying fault remains; heat, burning smell, or a tripped supply raises the urgency.
