I have a Bosch Nexxt 500 Series electric dryer. It is super sensitive to lint build up. The lint screen needs to be cleaned 3-6 times every time we dry a load and the signal drives us crazy! Is there a setting on the dryer or anything we can do to make it less sensitive? The lint screen is only 25% or less full of lint when it goes off. The exhaust duct to the outside is about 25 feet and is clean. Please, what can we do? 720-560-2205 or mvwparker@gmail.com
