ASKO t700 dryer thumping sound

Each time out T700 dryer drum rotates, there's a fairly lound thump. It's definitely a drum issue, as I can watch the drum & it thumps exactly the same time each rotation. If we need a new belt, is that something a DYI'er could do? Any other suggestions would be appreciated.

Re: ASKO t700 dryer thumping sound

Usually whin you get one thump (or a quick double thump) you have a dent in the roller surface of the drum itself. Easiest way to check this is to unplug the unit and take the top off by removing the 3 torx screws in the rear, then lifting the top off. Once the top is off look at the very front edge of the drum as you rotate the whole thing by hand. If you see any irregularities on the surface, thats your problem. If you see nothing it could be a bad motor or roller, but its unlikely if its happening in the same place on the rotation evry time. What has usually happened with dents in the surface of the drum is that the unit was set down too hard (or dropped) and the wheels it rests on dented the metal they ride on. If thats the case the only solution is to replace the drum or live with it .Good Luck!

The drum sits on two rollers, one of them might have broken like it happened to me. just replace it.

The drum stopped turning on our Asko t700 dryer even though the dryer motor works fine so it runs and blows air but will not turn. Both of the fuses seem fine and as I say the motor and everything else is...

the belt is broken, here is a thread:

here is a manual:

Hope it helps Tim

I have an ASKO T700 dryer. When I turn it on, it makes a high pitched squeak. If it's on for longer than a minute, I can smell a burning smell. Any suggestions?

you got a roller or belt idler not turning and burning the drum belt. you have to take the dryer apart and find the problem. if you need to lubricate a roller or idler use mineral oil or roller oil, do not use wd-40 or 3 in one.

When operating dryer makes LOUD thumping noise. Is this fixable?

this sounds like rotator wheel(s) are broken. It is some what an easy fix. The drum dyer needs to rotate those wheels. Usually you need two.

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

if you dryer is gas check out this gas no heat tip....

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...

Our Asko dryer (T720) has begun to make a heavy thumping noise, even if empty. (Sounds like a single wet & heavy object is in dryer)

Usually the drum rollers wear on that model making a thumping noise. The asko is a tough machine to work on. You may need a technician to service it.

Asko T700 loose belt, access from front?

I think you must replace the belt and the tensionarm. It MUST be done from the backside of the machine... Remove the backpanel, and the drum, change the tensionarm, and put the drum into the machine again. Put on the new belt, and mount it together again. Be careful for sharp edges! Hope this helps :-)

Seems like you need new drum rollers. If one(or both) is bad, the drum will rub in the plastic.
