After using the dryer, you need to clean the lint filter, and I think everyone does it.
The mistake that we are several to commit is to put back the filter in place, absolutely and we are sure to do the right thing.
Big mistake. And what you did not do could cause a fire!
First the explanation and then the solution! When using liquid softener in the washing machine or a sheet softener in the dryer, a part of the product is found on the lint filter, like a transparent film that can not be seen. And this transparent filter clogs the filter without anyone realizing it because we do not see it precisely!
In the video below, you will see the water remaining on the clogged filter, while normally it should pass through. And if the water does not flow, the air does not circulate either, which can lead to overheating ... and a fire!
The solution: it is necessary to wash the filter with water, soap and a small brush, to dry it and to put it back, every month.
See by yourself how clogged the filter can be!
