Bosch Tumble Dryer not fully drying.

jbellj

Hello, 

I have a bosch condenser dryer that only half drys clothes all of a sudden

Cleaned all filter, scraped out as much fluff as I can  and cleaned the moisture sensor.

Still not working.

Any ideas on next steps?

We had this with our tumble dryer and what we hadn't realised is that the belt had snapped so the drum wasn't actually moving when we turned it on! Still made all the right noises (from what I remember) though hence why we hadn't realised. Probably worth a look at this- obviously if you interrupt the cycle and open the door you can see if the drum has been moving around or not....

Twas a simple enough DIY repair once I'd figured it out.

Definitely spinning.

Are the clothes actually warm? Is the heater element working? Lint build up in condenser or round back? Is the reservoir down the bottom emptying and pumping water up to top?

Clothes are warm, removed as much lint as I could reach.

Water is getting to the condenser too. 

Worth taking the back off for a good clean up?

Are you using a timed program or a program that uses the moisture sensor to decide when to stop? Are you noticing that the program is finishing quicker than it did before?

Could be the moisture sensor that's had it. Try running a timed program on full heat with some towels etc and see if they come out dry.

Tried both neither make a difference.

Had another look, found some black cable, thread that might be the belt (or bits of it)

Will remove the cover and look later. 

Anyone know how easy to replace the belt on a bosch wtb84200gb?

As above that's what caught me out, so when you say you are sure that it's turning....

Very much sounds like your belt has snapped then and that's your issue. Just youtube your make and there'll be a video I'm sure. Took me about an hour, doing it slowly/methodically on our hotpoint. Almost wrote it off twice now being honest and each time it was a very simple/cheap fix.

Edit- just reminded myself. The other way I figured it out was moving the drum when off and door open, obviously, and you could feel that there was very little resistance..

Hi,

here's a wee VIDEO, might help.

I'm not sure on that model. Our Bosch drier is a heat pump and it was a pain to get to the belt to replace. You have to strip a lot of the machine down to get access to the belt to remove it. It took me a few hours the first time it went. About 12 month later the jockey wheel failed so I had to go through it all again. Was worth it though as Bosch quoted me £100 for a callout + parts. I think the new wheel cost me about £4 and an hour of my time to fit.

Hmmm maybe the heat pump ones are a bit more complex? I used the espares video and it does make it look a little bit griefy and you do have to take a lot of the machine apart/wiring looms etc. that said, there’s very little to a tumble drier, it’s all easily accessible. And, engineer call out is quite often more expensive than the machines worth, therefore normally nothing to lose, as you allude to…

The only thing I remember is slicing my fingers a bit on the metal edges of the panels so definitely gloves for that part. In the grand scheme of things it wasn’t difficult and that Bosch strip down video is almost identical to what I did.
