bosch wta 3100 no heat

[keiron12]

I have the above dryer and recently it has been going through its cycle but not producing any heat and therefore not drying the clothes. I think it may be a prob with the element, any way I can make sure?

Make sure the external vent is not blocked? Try running the machine and check the exhaust air flow? Is the drum rotating?

Hi
Here are main things that really tick off any dryer

1/ overloading
2/ blocked lint filter/vent
3/ stopping cycle before last 10 mins of cool down

If any of these are done then activation of the thermal cut out will almost be inevitable. Reset at the rear by pressing the red membrane.

This model doesn’t have one Greg, you’re thinking of the Crosslee/Bosch WTA2000 type maybe?

Hi
You know what Martin you are correct 😳
It does by memory have a re-settable cut out but is only accessible by removing rear panel.

I have a Bosch WTA 4107 which has also just stopped heating so does anyone know if this model has a reset button & if so where it is?

Many thanks

I could do with seeing my technical info I have at work, tomorrow!

From memory….

The models with a huge round (more donough shape) metal cover on the back, have a reset under that cover, toward to top of the machine.

Power off, of course!

Press the reset button, if it doesn’t click, then it’s not that!

If it goes click, you’ve reset it!

Try the dryer again to see if it resets again. If it does, you got a bigger problems. If it doesn’t reset you tryed to dry something to wet, or didn’t let the dryer cool down at the end of the program. The last ten minutes of the cycle (when the dryer cools down) are essential for reliablity.

Hi
This model has red reset on back.The element on these are different to other bosch vented dryers. Have had a few of these blown. Has a weird fitting aswell and if you have to change heater be methodical when disassembling.

Heater p/no – 492159

Thanks Greg,
I have found one very small red button to the bottom left inside the rear cover but this doesn’t appeared to have tripped so I am guessing that the element must have blown. As the dryer isn’t even a year old yet I am guessing that my best option is to contact Bosch themselves as I suppose they are the only ones that can do warranty repairs? I will let you know the outcome as soon as I know more.

Thanks again

Hi
Yes contact Bosch as you will have a 2 year parts and labour cover with a valid receipt.
