ParticipantI acquired this machine as raw, turns out the heater unit was busted, managed to obtain new heater unit for £70 plus VAT with the view to sell it on. Now it is working sweet, much better than my cheap indesit IS60V which was given to me by a neighbour and costed me £10 to put it right. The AEG performed so well that I am considering keeping it and flog the Indesit.
Anyway, this AEG dryer seems to “leaks” air via the door. I thought condensing dryer are supposed to be sealed, so can anyone confirm that it is normal or it needs new door seal?
Also there are some posts about diverting the drain pipe from the drawer to the drain. Can anyone provide me a link to a manual for this machine to see if it is possible? I am guessing that you need to program the machine to do that unlike some dryers you just pull the pipe out and plonk it into the drain outlet?

I found the manual, thanks Dave.
By the way, it blew the new heating element, for some reason it over heated and blew it out. Unsure if this is due to faulty heating element or thermostats in the dryer. Unless someone can come up with a likely source of problem? Otherwise I will decide to cut my losses and scrap it. Got my fingers burnt so to speak 🙁

if its blown an element it has to be airflow
what has blown on the element is it coils or overheat stats ?

I did some checks on the tumble dryer, it was producing no heat after successfully drying two loads then on the third load it stopped halfway through.
There are no airflow blockage as you can still use it without heat and there are lots of air flowing about.
The heater unit itself, the stat appears to be closed circuit which indicates working, only two of the wires (brown and blue) are closed circuit but the remainder 3 wires does not appear to make any contact as they are all open circuit and yes it was disconnected from the dryer when I tested it.
So it looks like blown heating element, it’s either faulty batch or something gotten too hot, even with all the stats working, it should have cut in. There were no burning smell well apart from slightly hot smell that burns the hairs of your nostrils when the dryer stopped mid cycle on the third load. It was a child’s bedding (duvet cover, sheet and pillow cases). I thought perhaps it was too light and restricted the airflow but discounted it.
The worse thing that the heating unit was a special order and therefore non returnable. What my chances are to ask for refund via Connect?
any ideas? 😕

looking at the element pictures it shows 2 thermal fuses at the top of the element assembly. although they say they are not replaceable they look like microtemps and you mat be able to change
as for connect i have got faulty part from connect that other people have sent backhave had a look at prices best i have found is aeg themselves

£87.44 delivered and if you rang lux trade you would prob get 20{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} off that
as far as fault is concerned i would look at the relays on the pcb. if they stuck on then element would come on without fan and blow microtemps. see if element is powered without unit running
hope it helps

Thanks Dave,
The part came from Connect as special order for the price of £70 plus VAT. Will have a closer look on the micro temp.
I will take a look on the pcb board when I get the chance. Some threads seems to suggest that PCB board are often the main culprit for small things to go wrong. I find it odd that you mentioned the heater relay would stay on even after the fan had stopped running. Is it common for this to happen? And what do you mean the fan stop running? Was the heater meant to stop heating when the drum goes into reverse (I would have thought so)? Where would I find the relays (behind the facia or on the base)?

just had a white knight with same problem. machine stopped but heater was on as soon as door was closed. relays are mechanical and fail a lot. just ordered relays for a miele td that is not turning element on also just had a miele washer with reverse relay failure
trace element wires back to board may be connector P
info should be in manual or it is in mine

Did a thorough checks, both micro temp busted on heating element.
Traced wires to circuit board, none of the relays are closed circuits, all of them open apart from two connections which leads to the interior light from the relay (middle relay out of 5) and via those one of two small blue boxes by the description of 6n8 M 250v~Y2.
Other than that all the connections are ok. Had a hard time tracing those brown wire…
Discovered the front stat is open circuit and no changes in resistances during hot cup test.
Possible conclusion – front stat seized up and made the heater over heats and blew out micro temps.
Expensive to put right as thermostat costs £13 plus new heater £84 considering the “new” heater lasted for two loads. Scrap yard it is!
