Dryer wont heat and check filter light is on but filter in dryer is clean?

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.

the blinking filter light is just a reminder, not connected to anything. goes out when you start cycle. however, if the dryer overheated then it may have blown the thermistor fuse. check out appliancepartspros.com or repairclinic.com for how to videos and parts.

Sounds like your heating element has went out. So you will either have to replace it $100 to $150 or purchase a new one

The filter screen check light is just a reminder indicator. It will always come on whenever you turn on the power. As for the heat, you didn't state whether it's electric or gas.

We have the same dryer and the check filter light always comes on at power up but goes off when starting. Is yours still not heating? as I see you question is a little old now. let us know.

Empty the bottle and then unplugg the dryer. Plugg the dryer back in and see if the empty light goes off.

Have you checked and cleaned the duct comming out of the dryer? Clean the whole length.

You might need to check the exhaust on the rear of the Dryer, or the blower motor iether one has lint inside, restricting the air flow

I just cleaned those sensors at the bottom of the filter, it worked like a charm. The dryer is now drying perfectly, I did not know you were not supposed to use fabric sheets with this dryer. Now I know, Thank you for the good information.

The check filter light is just a reminder light and cannot be reset.  Nothing to worry about.  Just keep the filter clean before each use.
