More Details
This is a genuine heat exchanger unit for your tumble dryer.
It removes moisture from the air inside your dryer by cooling warm, humid air from your clothes. This turns the moisture into water that’s collected or drained away after.
If you see water pooling inside or around the dryer, the heat exchanger might be clogged or not draining properly, leading to excess water buildup. It's best to change it with this replacement part.
This heat exchanger unit is from Bosch. Also fits Balay, Constructa, Gaggenau, Neff, Pitsos, Profilo, Siemens, and Viva tumble dryers.
Before ordering, please verify that this part is suitable for your model using our compatibility checker.
