- Troubleshooting on Bosch, Neff, Siemens sometimes your tumble dryer will have an intermittent fault
I will show you How to Diagnose the fault, it may start and run for a few minutes and then cut out, there may be no light on the control panel, the tumble dryer will not start, nothing works, the dryer kept stopping soon after switched on, tumble dryer keeps stopping after a few minutes etc, etc. this can normally be a fault with the tumble dryer printed circuit board known as the PCB. if you have power getting to the PCB from the mains lead and electrical filter or known as a suppressor then you may have a damaged board it is quite common for the link switch to blow as if they get hot (normally caused by voltage drop) in this video I will show you how to repair and fix your tumble dryer.

Thanks for a great video. I am a electronic engineer so decided to repair the board on my very similar Siemens machine (model WT44370NL/04) The switching chip in this machine had also failed (it had exploded!). I removed the chip by first cutting each pin and removing them individually. The circuit board tracks are thin so it's necessary to be gentle when removing the pins. then the holes need to be cleared of solder using a solder sucker. In order to make any future replacement of the chip easy I fitted a 8 pin dil socket into which the replacement chip was inserted. (make sure to fit the chip the right way round). This switch mode power supply chip is fed from the main rotary control switch via a discrete 47 ohm wire wound resistor which had also failed (colour coded yellow viiolet black). It's necessary to replace with one of sufficient power capacity (the old one looks to be about 2 or 3W). I have traced out some of the switching power supply circuit but the application note document for the TNY266 chip can be found on the web and is not so different from the circuit used in the machine.
Switch mode power supplies are very common. The a.c. mains is rectified into a high voltage d.c. source. The switching device chops the high loltage d.c supply to produce a high frequency a.c waveform which can be efficiently passed through a small transformer to produce the required low voltage supplies and also provide safety isolation. Feedback control is provided via optocouplers (this machine uses 2) into the enable (EN) pin of the TNY266 chip. donation sent.
Great video, followed the well shown methods for dismantling the dryer, sent board away as advised, great service by repair company. Reinstalled board as shown. Saved either paying out £280 for replacement board or buying a new tumble dryer. Thank you.
Thanks useful info and handy board repair service.

Since we work very hard in our warehouse making free video guides for you all on appliances, we always appreciate a beer, offering a choice of single or round beer. www.how-to-repair.com/help/buy-paul-a-beer/
I did this job last year in Oktober, the dryer runs now perfekt. I always enjoy your videos, learning English and repairing. Best wishes from Germany
Great to hear! I'm glad you enjoyed the video please remember to subscribe as that's what keeps us going. Tschüss
I think I am in love with this man
Thanks for the help Paul. You saved me at least $650! Enjoy your beer!
Another brilliantly demonstrated dvd. Many thanks for your time and expertise. 👏👍👏👍👏👍🏴
Brilliant stuff, really well explained and filmed - thank you. I've tested that power is getting to the PCB and have now packed it off for repair - fingers crossed they can sort it and I'll have it back and running again in a few days!
update - I got a notification about 2 hours after my parcel was delivered to the repair guys, to say my parcel was on its way to me. They must have whipped it out, replaced the chip right away and sent it back. Apart from a slight mix up in getting the wiring exactly as it should be, it's now running just fine again. Thanks so much!
Hi There I’m an electronics engineer and have just repaired a circuit board shown in your video. The fault was almost the same as you were having. Would not start tumbling but would briefly try to start but would not run and the start light would just start flashing again.
The fault was a small 10uf 400V electrolytic capacitor on the circuit board. It’s in that switch mode section of the board you were showing.
You just need a soldering iron and a replacement electrolytic.
Thanks for the tip with the control selector with the small cutouts in it.
I would love you to leave your opinion on our poll about manufactures building in obsolescence to appliances. ruclips.net/user/postUgkxygHomnUySd_bYjaJBdEHPO6T4dYo9Ahm

@@How-to-repairMy Miele professional tumble dryer won't power up today could that be the same thing
Thanks for the information on the PCB repair service. I might have to use their service to fix a programme selection knob on a bosch WTL5400 drier that randomly chooses another programme by itself, interrupting and stopping any programme already running.
Thanks
Thanks!
Thanks for the donation mate. I will use it to upgrade my technology to be able to record better quality videos. Cheer!
Thank you, i repaird my dryer with your help.
Really glad you got it up and going again glad we could help you @erwinvantvelt423 this is for you ruclips.net/user/shortse432SAb2g08 please remember to subscribe as that's what keeps this channel going. Thanks 👍
Hi , love your videos , ive found a few solutions to dryer problems , now here is my question , if the mains filter suppressor is dead/blown, will that cause the dryer to have zero power at the circuit board ? its a Grundig GTN27110 Condenser Tumble Dryer Thanks in advance
Great content as usual I’m also looking forward to the drive belt change as well..
Coming soon! not sure it will be on this one as already started other video but its on the list mate. only so many hours in a day
I totally understand 👍
I worked quite a few hours extra to make you this, but it looks like it's going to be a worthwhile video i hope it helps you. Bosch made belt replacement ruclips.net/video/jweshDZymS0/видео.html should be uploaded in an hour
Thanks a lot for the video. I have just had this problem and looks like this could be the issue.
I own you a beer 🍻

Hey, thanka for the video.
Can you tell me, does Siemens tumble dryers has a restart program?
Nice repair, thanks for the video
Thanks for watching! it should safe some waste in the world
Great videos..what do you think on a bosch 300 series error e02 ...cleaned out heater was blocked and co denser was cleaned .. no air flow blockage
Excellent vid. but I can’t find the link for the board repair company, help please..
Thank you. Very helpful. I couldn't find anyone can fix the circuit board in my country. Does anyone know the value of the burnt out resist. Looks I have to fix by myself. thx in front.
I guess this information would apply to a Miele model T 9747 WP tumble dryer. It has stopped in the middle of a cycle and won't restart checked every thig including changing a leaking capacitor on side of compressor element
some will
nice video. i followed your video to take a look at my siemens iq700 dryer. it seems nothing is wrong with the board. but i did smell a burning smell where the power cables come in to a power relay or something. but been looking on the net for that part and cant find anything.
This sounds like you're describing the suppressor or electrical filter. If you use our website with your full model number I should be able to help attach the link below. Have a great Christmas and a happy New Year. Can't guarantee we will get the part before Christmas or New Year. Hi @crazyfluteplayer6216 I will need the full model number of the identification plate please use our contact us page and make sure you fill out the request of what part you are after and will get back to you within 24 hours normally www.how-to-repair.com/help/contact-us/

Great video! Thank you to share your knowledge with us.
My Siemens IQ 500 start cutting off the main power. First after 10 min work, and now straight away after pressing the Start button. Didn't spot any burn smell or overheated cables. How to recognise this part( on the video) is faulty? It should be kind of melted, or?
Thank's a lot for your job!
Edit. Put my comment on the wrong place.
Should be like a separate comment. Sorry.
I cannot find the link to the company which repairs PCBs...
I have the same problem: Bosch Classixx 5 Washing machine shuts off after about 5 minutes.
Hello , i want a help please, I have a BOSCH dryer model WTY888W0GR/16 and the problem is that it takes 4-5 hours to dry the clothes, it showed an E25 error once, i dont know what is the error E25. I cleaned the condenser very carefully, then it dried faster and after 1-2 months it does the same again, it is slow to dry. I noticed that the heat pump does not work continuously but stops for 20-25 minutes and starts again and continues with this routine. after 5 hours it starts and dries them normally within 30-40 minutes and stop, after the stop apper in screen ''please clean the filter'', I have cleaned the filter at the beginning. I see that the wattmeter that it consumes 450-480watt when working head pump. Do you know the problem please? Thank you in advance.
My Exxel Bosch tumble dryer works but it goes dead every 5 minutes and starts again on it's ow and off again.
I checked the oveheat stat but seems ok.
Will be the same issue with the PCB?

Hi, I watched your video which was very informative and removed the PCB from my Bosch \Classixx 7 condenser drier. However, I am having trouble contacting the repair company to which you refer. Could you give me the contact details. I tried, thinking I was calling a company called qer Ltd but my call was answered by a national company that only do call-outs rather than letting me send in the PCB for repair. Having taken off the board it would be a shame not to complete the repair myself. I live in the hope that you can come through. Cheers, John
