The vacuum was working fine and it suddenly turned off while it was running. The vacuum had a new bag and the filters were not dirty. It will not turn on again. I tried to plug it into different outlets, but it will still not turn on.

Did you use it to vacuum up fine materials like powder? If you cleaned the filters, but they are original to the machine, replace them. Try changing the bag to a fresh one as well. Beyond that, check how freely the brush turns. If it doesn't turn freely that can but excess load on the motor, if its covered in threads, remove those.
Be sure the upper attachment hose is inserted firmly into the lower hose into the nozzle. Check for suction at the end of the hose, and if there is no suction there must be an obstruction in the hose, or the filter inside the bag compartment is plugged. Be sure the brush is turning when the handle is released.
It's possible the thermal reset is defective. It shuts the motor off if it gets hot. Remove the bag door and take the bag off, remove both filters and then turn the vacuum on, just leave it sit there with the motor running. This eliminates the bag or filters causing any airflow resistance. If it still shuts off after a few minutes it's likely the thermal reset is bad. Some vacuums have an external thermal reset button which can be replaced if necessary but on your model it is built into the motor and you must replace the motor. If the motor runs fine put the bag and the filter under the bag back in - (make sure the filter is clean and not restricting airflow) put the bag cover on then turn it on again. If it overheats and shuts off then you may have a clog on there somewhere restricting the airflow. If so check the power nozzle area, the hose coming from the power nozzle, the extension hose and wands for clogs or restrictions.
Same problem. I suppose BOSCH dumped these into the market and have chosen to disown them. Support is pitiful and vacuums have also been taken off their website. Too bad, was a nice quiet product for the 2 months it worked. Solution = new, non-BOSCH vacuum.
I suggest checking the filter. If it's coming from the HEPA filter area, the filter might be out of position or possibly you have the wrong kind of filter. Miele uses 2 different types of HEPA filter so that could be the problem.
Hi there SmartAlec from Nelsonvacuums.com.au here.It sounds like a blockage of some kind. The best way to find it is to set the machine up for normal vacuuming and remove one component at a time until the suction returns. eg turn on and feel suction under floor head - not good? then remove the rod, then the hose. Once at the machine on its own it gets a little triky as i don't know which model you have. However if you have a bagged model remove all the filters and the bag and retest. There will be at least 2 filters, one before the motor and one after (maybe under the vacuum or right at the back). If it is a bagless model even though the filter may look clean it is probably blocked with very fine dust. If suction returns when the filter is removed then you need to buy a new filter. I am a nilfisk vacuum cleaner agent so i can supply a filter for you. If this still doesnt help you are welcome to call me if you live in australia my contact details are on my website www.nelsonvacuums.com.au. Hope this helps !. Happy vacuuming :)
The other possibility is there is a blockage in the foot. these models have dual channel air flow (windtunnel) and become blocked when not cleaned depending on use. under the roller there is a cavity that can be removed for cleaning. a hot motor can be caused by poor air flow.
I had this same problem. All of a sudden it shuts off while vacuuming and then i'd have to wait a while before it would turn back on. Finally it stopped working period. Before going out to buy a new vacuum, I decided to take the thing apart and clean it up really good. That included running a clothes hanger through the tubes to get all the stuck hair out, removing the roller and getting all the hair untangled from it, and rinsing out the air filters (both the sponge and the plastic piece with the paper like filter) with hot water. Then you let the filters dry for a day or two. The plastic/paper filter takes longer to dry so I used a hair dryer. The vacuum itself is not hard to take apart. I think there are only 11 total screws you need to take out. After the filters dried I put them back in the newly cleaned vacuum and it worked like new. I think the main problem was the condition of the filters. They can get pretty filthy over time, which will limit the air flow to the motor. With less air the motor is more likely to overheat and shut off. So keep your filters clean and you shouldn't have any proplems.
