We continuously had a similar problem with signals forever coming on after just a few dryer loads. The problem was corrected when we took the back off of the dryer and cleaned the recirculating fan and removed a rubber glove that somehow came through the system and blocked the air flow at the heating element. Low air flow is the same as plugged filter and apparently the computer in our German-made Bosch dryer simply says that. We cleaned the area well, removed all traces of the glove and restored the dryer to operation. We have not had the filter problem since. We routinely clean the heater area at the back of the dryer to maintain our sanity. And we now dry our clothes. Bosch never responded to my query.

I posted in late December on the lint alarm and what I discovered was a bit alarming. (no pun intended) Lint had been accumulating on and around the heating coils used to dry our clothes. Some of the lint was burnt and the remainder, amounting to a small handful, was caught up in other area's around the lint sensor. After carefully cleaning the heating coils (with a tooth brush) and removing the rest of the lint and successfully putting everything back together, we have not had a lint alarm issue since. (Touch wood). No need to replace the lint sensor or any other parts. It was not that hard to take apart the back and remove the heating coils to clean, but it requires the unit to be unplugged, careful attention to what came off and where it goes back on. After what I found, I will be cleaning the heater coils out once a year. Which then raises the question. Should a person have to do this? The obvious answer is no! But from time to time we buy things that are not what we would expect and do what we need to do to make it work. From what I can tell, lint is getting past the lint filter and ending up where it shouldn't be. Hope this helps any of you that are having the same issue.

I had the same problem and figured if the lint sensor is clogged, covered or otherwise gummed up with lint, dirt, hair, etc then this will continue to happen regardless of wether the lint trap is clean.

So I took my compressor and blew out the slot where the trap slides into...stuff flew everywhere (so watch your eyes or wear goggles). I then vaccumed it up and did it again... and again and again each time loads of stuff came out. Once nothing blew out I loaded the dryer and have not had the problem since...

This makes sense right? so if you can try this solution.

Make sure the exhaust vent duct is clean all the way to the outlet.
