Lint filter sensor cuts off machine within 5-10 minutes.

The issue you are experiencing with your Bosch Maxx7 sensitive dryer could indeed be related to a faulty heat sensor or a clogged vent. Here are a few troubleshooting steps you can try:

1. Check the vent: Ensure that the dryer vent hose is not clogged or blocked. A blocked vent can prevent hot air from circulating in the dryer and trigger the overheat sensor to shut down the machine.
2. Clean the lint filter: Remove the lint filter and clean it thoroughly. A clogged lint filter can also cause the dryer to overheat and shut down.
3. Check the heating element: If the heating element is faulty, the dryer may not heat properly or may overheat and trigger the sensor to shut down the machine.
4. Reset the machine: Turn off the power to the dryer for a few minutes and then turn it back on. This may reset the machine and resolve the issue.

If none of these troubleshooting steps resolve the issue, it may be best to contact a qualified technician to inspect and repair the machine.

Unsure if your model has a front housing to be checked.

I would recommend you have someone take the dryer completely apart and clean the lint out. In the last 3 months, I have cleaned out 2 or 3 shoeboxes of lint from each of 5 machines.
This has nothing to do with the filter screen you are supposed to clean after every use.
It has to do with the lint that escapes the ductwork inside the machine itself.
You may be amazed how much you will find.
You will also need to check the ductwork from the back of your machine to the outside air. That pipe can also get clogged and cause the same results.
Be blessed.

Instructions

Dryer Does Not Turn On
1

Ensure that the dryer's power supply cord is firmly plugged into an electrical outlet.
2

Inspect the structure's fuse box for a tripped fuse. Each fuse is assigned a single "On/Off" switch. If any fuse switch is in the "Off" position, flip that switch to the "On" position. If the problem persists, contact a professional electrician.

3

Press the "Start/Stop" button on the left side of the dryer's control panel.
4

Close the dryer door firmly so that the door clicks into place. The dryer will not operate if the door is not shut.
Lint Filter
5

Clean the lint filter. Twist the program selector knob on the control panel to the "Off" position, then open the dryer door. Pull the lint filter out of the dryer. The lint filter is located at the front of the dryer's tumbler, and is inserted vertically into the dryer. Gently stroke your hand over the filter to clear the lint, then reinsert the filter and close the door.
6

Turn the dryer off and allow at least 30 minutes for the dryer to cool, as excessive heat can cause a drying program malfunction.
7

Increase the ventilation of the room the dryer is located in, such as by opening a door or window. Excessive heat will cause the dryer to automatically turn off until it cools as a safety measure. Increasing the ventilation will help keep the dryer cool.
Clothing Not Fully Dry
8

Clean the moisture sensor. Open the dryer door to access the moisture sensor. The black-colored sensor consists of two bars, and is located at the front of the dryer's tumbler, to the left of the lint filter. The sensor should be cleaned with a clean cloth and white vinegar once per month.
9

Clean the lint filter. Twist the program selector knob on the control panel to the "Off" position, then open the dryer door. Pull out the lint filter. The lint filter is located at the front of the dryer's tumbler, and is inserted vertically into the dryer. Gently stroke your hand over the filter to clear the lint, then insert the filter back into the dryer and close the door.
10

Spin the laundry at a higher spin speed in the washing machine before placing the laundry into the dryer to reduce the moisture content.
11

Turn the dryer off and allow at least 30 minutes to pass for the dryer to cool, as excessive heat can cause a drying program malfunction.

It might just be time do do a little cleanup. No matter how good you are at cleaning the filter, lint is still gonna build in the dryer.


took the back dust cover off

While you are at it take the whole dang thang apart

speaking of a noise maker:




Go through it and do a good cleaning. No parts needed for that. then retry.

Code AF means the air flow is blocked.
Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance.
Your dryer has some internal ductwork. If it gets clogged, your dryer can't dry properly. In most dryers, to get to the internal ductwork to clear the clog, you have to substantially disassemble the dryer. A quick way to check for internal clogs is to remove the lint filter and use a flashlight to inspect the inside of the duct. If it looks clogged and you can't clear it using your vacuum.

Sounds like the vent is plugged. Disconnect the vent hose from the vent and test again. If it drys normally your vent is plugged and will need to be cleaned.

Remove the exhaust vent from the rear of the dryer. Run a timed load at 45 minutes. If it dries correctly clean your connecting vent your wall vent and the lint from inside the machine.
