Quick answer
AEG's dryer guidance treats EHO/EH0 as a possible power-supply problem, including low, high, or unstable voltage. Because the task has no complete model or region, first photograph the display and nameplate and confirm whether the final character is the letter O or zero. If the socket is dry and there is no heat, smoke, scorching, sparking, or damaged plug, a simple external socket check with another small appliance is allowed; never use an extension cable. AEG permits one 30-second unplug/reset, but if EH0 returns, the display is unclear, or the supply is abnormal, stop using the dryer and arrange an Authorized Service Center or qualified electrician rather than opening the dryer or testing live voltage.

Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Stop the dryer and photograph the complete display before resetting it. Record whether it reads EH0, EHO, EH:0, or another combination, including any flashing lights or beeps, then copy the complete model/product number from the rating plate and note the country or market.
Expected result: The final character is clearly a zero or letter O, the code has a different punctuation or suffix, or the full model/market is still missing.
Next step: Match the exact display and full model to the AEG support page/manual. If either cannot be confirmed, leave the dryer off and give the photograph and nameplate details to AEG service.
Why this matters
Why: AEG's opened article groups EHO and EH0 with a power-supply problem, but a different code or an unmatched model may follow different instructions. “AEG dryer” is not enough to select a model-specific manual or component.
-
Check 2
From a dry standing position, look and smell for a hot or scorched plug/socket, smoke, sparking, melted plastic, a damaged cord, or a breaker/RCD that trips again. Do not remove covers, probe the outlet, or keep trying the dryer if any warning sign is present.
Expected result: There is no visible or smelled hazard and the socket is dry, or there is heat, smoke, scorching, sparking, visible damage, or repeated protective-device tripping.
Next step: For any hazard sign, stop using the dryer, isolate power only if it can be done without approaching heat or damage, and contact a qualified electrician or Authorized Service Center. Do not reset and run another cycle to see what happens.
Why this matters
Why: A visible electrical hazard cannot be safely separated into a house-supply issue versus an appliance fault by a code alone. AEG warns against extension-cable use because it can create short-circuit or fire risk and directs wiring problems to an electrician.
-
Check 3
Only when the socket is dry and shows no damage, check it externally with a simple known-good low-load appliance such as a lamp. Do not use an extension lead, power strip, improvised adapter, or another high-load heating appliance for this check.
Expected result: The other appliance also does not work, or it works normally while the AEG dryer still displays EH0.
Next step: If the socket is dead or intermittent, stop and have a qualified electrician check the household supply. If the socket works, continue only to the single AEG-permitted reset and then service if the code returns.
Why this matters
Why: If the same socket is dead, the external supply or wiring becomes the first service boundary. If it works but EH0 remains, AEG's guidance still allows an unstable supply or an appliance-side fault; this check does not prove the dryer control board is bad.
-
Check 4
If there is no hazard, the plug is safely reachable, and the socket supply is stable, remove the dryer plug for 30 seconds and reconnect it once, exactly as AEG describes. Do not bypass the safety switch, open the cabinet, work on energized wiring, or repeat the reset loop.
Expected result: EH0 clears and stays away, or it returns immediately/after selecting a program.
Next step: If EH0 returns, leave the dryer unused and arrange Authorized Service Center support. Provide the model, market, exact display, socket-check result, and reset result; do not order or replace an internal part from EH0 alone.
Why this matters
Why: A one-time clear is compatible with a temporary supply interruption, but it does not prove the dryer or household wiring is sound. AEG says to contact an Authorized Service Center when the suggestions do not solve the problem.
-
Check 5
Do not use dryer-type assumptions for a missing-model machine: identify whether the unit is condenser, heat pump, or vented only from its nameplate/manual. If moisture, condensation, or a vent warning is also present, record that separately without moving the appliance or disconnecting a vent hose.
Expected result: The type is confirmed as condenser/heat pump, confirmed as vented, or cannot be identified; moisture or a vent restriction is present or absent.
Next step: Use type-specific maintenance instructions only after EH0 and any electrical concern are resolved. If the type or manual cannot be matched, stop at external observations and ask AEG service to identify the correct procedure.
Why this matters
Why: AEG says some checks apply only to particular dryer types and directs the user to the supplied manual. Room conditions, filters, condensers, or venting can affect operation, but they do not establish the electrical meaning of EH0.
Use your observations
Decision map
Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
The socket is dead or intermittent when checked safely with a small appliance.
Do this next
Leave the dryer unplugged and have the supply checked by a qualified electrician. Do not use an extension lead or move the dryer to another circuit as a workaround without resolving the supply concern.
Why this path and its safety boundary
Why it matters: The first supported branch is the household socket or wiring, not an inferred dryer part. AEG specifically directs wiring faults to a local electrician.
-
PATH 02Next step
What you see
The socket works, there is no external hazard, and EH0 returns after the single 30-second reset.
Do this next
Stop using the dryer and contact an AEG Authorized Service Center with the full model/product number, market, exact display, and timing. Do not open the cabinet or run repeated cycles.
Why this path and its safety boundary
Why it matters: AEG's guidance leaves an unstable supply or an appliance-side fault possible; the public information does not identify a model-independent heater, motor, sensor, or control-board part.
-
PATH 03Next step
What you see
EH0 clears once and does not return, with no heat, smoke, scorching, or breaker/RCD symptom.
Do this next
Use the dryer only under the exact model manual and stop immediately if EH0 or any electrical warning returns. Record recurrence rather than repeatedly resetting it.
Why this path and its safety boundary
Why it matters: A transient power interruption is possible, but the reset is not a safety certification or proof of a stable appliance supply.
-
PATH 04Next step
What you see
The display cannot be distinguished as EH0/EHO, the model is incomplete, or the dryer type/market cannot be matched.
Do this next
Keep the dryer off if the code persists and ask AEG or an Authorized Service Center to identify the correct manual and safe next step from the rating plate.
Why this path and its safety boundary
Why it matters: The identity evidence is insufficient for model-specific code interpretation. Vented, condenser, and heat-pump instructions are not interchangeable by default.
Helpful context
Understand the symptom
Why the missing model matters
EH0 is used across AEG dryer documentation, but the opened AEG support article expressly applies to condenser and heat-pump dryers. It does not establish that every AEG dryer, every market, or a vented model has identical reset timing or controls. Treat this as a safe first-response guide until the complete model/product number and country are matched to the AEG manual. Do not infer a failed board, motor, heater, or socket from EH0 alone.
When checks do not resolve it
Need a professional?
Stop using the dryer and seek professional help for smoke, burning smell, scorching, sparking, melted plastic, a damaged plug or cord, a hot socket, repeated breaker/RCD trips, a dead or intermittent outlet, a returning EH0/EHO, or an unclear code/model. Never use an extension cable, open the cabinet, bypass protection, or perform a live electrical test.
Common questions
FAQ
Is EH0 always the same fault on every AEG dryer?
No. AEG's opened support article groups EHO/EH0 with possible low, high, or unstable supply and applies to condenser and heat-pump dryers. The full model, product number, market, and dryer type still need to be matched before using model-specific instructions.
Can I reset an AEG dryer showing EH0?
If there is no electrical hazard and the plug is safely reachable, AEG describes removing the plug for 30 seconds and reconnecting it once. If the warning returns, stop using the dryer and arrange service rather than repeating the reset.
Can an extension lead solve EH0?
No. AEG explicitly warns not to use an extension cable with the appliance because it can create a short-circuit or fire hazard. Have an abnormal outlet or wiring checked professionally.
