I've had my T780 for about 6 years. A year or so after I got it, it overheated. That's when I discovered the vileness that is the condenser, and learned to curse the Asko engineers for:

Locating the condenser behind an access door attached with two Torx screws;
Putting the overheat reset button on the back, requiring me to climb my W660 like a monkey and hang over the top of the dryer, praying that it doesn't tip over and kill me.

Since then the overheating problems have gotten worse. Last year I had to clean the condenser weekly or the dryer would overheat, and even then I could only use the "low heat" mode -- not fun on a condensing dryer. Now even with a freshly cleaned condenser the unit overheats if I run it with more than 1/3 of a laundry load (e.g., 1 queen size sheet).

When one of the drum wheels went bad and I had the repair guy out, he had no idea what was wrong. Asko is no help. Any suggestions would be very much appreciated.

Thanks!

clean the lint screen with soap and water so it will flow maximum air. sometimes after cleaning all of the lint out of the dryer and blower i will run it with the door open to burn off the lint cuaght in the heater (only do this if you clean the dryer first you could have a nasty fire). These two things usually provide enough extra airflow to prevent overheating.

Thanks! I'll try cleaning the lint filter with soap and water tonight and see how it goes. I assume you run with the door open by jamming down the latch?

yes you hold down the latch. by running it with the door open you are putting no air across the element and it gets hot enough to burn the lint trapped there. the asko screens are extrememly fine so the slightest bit of buildup will drastically reduce airflow. you may soak it in hot water soapy water for a bit before gently scrubbing with a soft brush

I washed clean the lint filter and its plastic carrier pieces, removed and rinsed the door gasketing, sprayed out the condenser, ran a dryer cycle with the door open, and plucked the lint from the condenser inlet area and the lint trap outlet. Then I did a load of towels in the wash and dried them on regular heat (not low)...

It worked perfectly, like a new dryer!

THANK YOU! You saved me hundreds of dollars. You (and Fixitnow) are tops.

Especially for the ASKO dryer T780 there is a point of general importance to check: is the lint filter OK or not?

In my case the dryer started to overheat as soon as I got it, which of course was very annoying (I bought it used quite recently). Cleaning the condenser didn't help, so I went on to investigate the problem in more detail. After checking the forum posts here, overheating seemed to be a common problem with the Asko T700 series. I then checked out the blower and found out that it was more or less jammed with lint! There was not only a lint-rat there but a whole colony of rats... No wonder the dryer was overheating and stopping all the time...

The reason for the lint build-up inside the machine was that the lint filter screen showed a long but tiny slit in the screen material close to the filter plastic frame in both set of frames (difficult to see at once). This meant that lint from the textiles in the drum would blow straight through the holes in the filter when the machine was running... Maybe the filter had been damaged by the former owner during cleaning or the screen simply was worn out. Anyway, a filter replacement is obviously needed.

So, if you experience overheating problems with the Asko dryer, start by checking the filter unit on the inside of the door and replace the unit if you see signs of clogging or wear. You must also carefully clean the blower as well as the condenser to ensure a free flow of air.

Before I start using the T780 again, I will in my case now have to dismantle the entire machine to get rid of all the baby lint-rats that can be found everywhere, in order to prevent new rat colonies accumulating in the future. For that purpose a repair manual for easier access to the dryer interior would be of immense help. Mighty Samurai; I assume a donation to the beer fund will do the trick, or?

By the way, my Whirlpool washer (AWM 6140) is working alright, but when the drum spins a machine gun-like sound is heared during speed up/down (imbalance?). I suspect the time has come to replace the rollers, or what do you think? Also here, a repair manual would come handy.
