    I have an AEG 16830 washer dryer. I have owned it from new without any issues. The dryer has now started cutting out after about 10minutes of operation. If I set the dryer to a 103 minute cycle (iron dry) the heater warms up, the drum starts rotating, the dryer fan starts. The heater then cools down after a couple of minutes and doesn’t warm up again and then the dryer stops after about 10minutes and the timer jumps from 93 minutes to zero.

    This happened a few times earlier in the year but then seemed to rectify itself until last week. I’ve researched the problem on this site and others and followed the advice. I have dismantled the machine so I can clean the condenser, ventilator assembly and check the probes and regulators.

    Both temperature probes (hose dispenser and dryer duct) have an impedance of about 5kohms which I believe means they are OK. I also checked this at the PCB connector end to check the probe wires are OK.

    The dryer heating element is working with about 60ohms impedance on each element, 230v when the dryer first starts and it warms up, although it cools again after a couple of minutes and never seems to warm up again.

    While checking the temperature probe under the condenser one wire came off, I read elsewhere on this forum that lose connection on this probe is a common fault for the dryer not working, so I replaced the connectors as described in the post. However this did not rectify the problem.

    I checked the error code, first resetting the code to E41 (starting a program with the door open), then tried a long drying cycle this stopped after about 10minutes, the error code after the dryer stopped prematurely was E73 indicating the dryer duct temperature probe. But I have previously tested this to be OK with 5K impedance.

    I have tested the connector and wires for the dryer duct temperature probe and they are OK.

    So I’m now at a loss as to what the problem could be and run out of things to try from previous posts on this forum.

    Is it possible that the dryer duct temperature probe is still at fault even though it has a room temperature impedance of 5k ohms? How does the machine know this probe is at fault – what is it testing for?

    Could the problem be with the PCB and is there any way to test for this?

    Any advice on what I should do next?

    Thanks

    Not known at least to me.
    Have you tested the dryer elements for earth leakage as this can cause loads of strange problems and is a very very common failure point that does not necessarily throw up any fault code but does throw up sometimes a miss leading one. Do not go thinking that the dryer element/s if trickling to earth will bang out a trip, they rarely do. Also not the rarer fault of the heater works but then fails, not because of an earth fault but it just fails cools down might work again for awhile then breaks down. Like I said not that common that one but came a cropper once or twice with that one.

    as far as I can see the NTC should be between 5765 ohms and 6050 ohms at 20 degrees C
    you say you tested at room temp but we have not had 20 degree days recently so I would expect resistance to be higher than 5k
