SOURCE: Miele White Star SEB 204,

Yes, most likely the belt has stretch. Flat belts do this after a short time and need to be replaced when problems start with the brush roll not wanting to turn. Also check the brush roll, make sure that the ends turn freely, if not, then replace it also.

SOURCE: The powerhead brush died. The vacuum works just

there could be 2 reasons for this problem.

one) the powerhead is dead legit as in there is no power coming to it or the motor is actually dead.

2) something jammed in the brush and popped the reset button. The reset button is a red button located as your looking at the back of the powerhead on the right side. Usually a red square. Push it and it SHOULD start up again.

That being said, if you have done the reset button and it still does not work, that unit I beleive has either a 2 or 5 year warranty (cannot remember dont have the documentation in front of me) and if it is still covered under warranty for you, take it to your closest Vacuum repair shop. Do take the hose and powerhead with the cannister unit.

good luck

SOURCE: Shark SV736R motorized brush won't rotate

The 2 metal pins of the motorized brush are not in contact with the vacuum cleaner. or the Motorized brush is clogged up. You have mentioned that it is cleaned, but still give a thorough inspection. For the metal pins, firmly insert the motorized brush into the air-intake nozzle. This will connect the motorized nozzle to the unit power supply.

SOURCE: my rotating brushes have stopped rotating

Almost certainly you have broken a drive belt. It is not a big deal though just turn it upside down and remove the base plate you should be able to access the belt from there. You should be able to get a belt pretty easy from an online retailer like vacuumspot

My shark rotator brush won't spin. How do I fix it?

Check out this Video

One of the most important parts of the Video - It's a great Video by the way - is the switch being shown at the 3:08 mark in the video. I recommend watching the entire video to see how to disassemble the Power Brush Assembly. Anyway, if that switch shown in the Video fails, it will prevent the beater bar (rotating brush) from working. It could be stuck on or off. Ours was stuck off and would not turn on. The switch did not spring back and click like shown in the video.

This happened on ours and a quick call to Shark Corp got a replacement Motorized Floor Brush Assembly on the way and a prepaid shipping label to send back the defective one.

They need your model number on the silver sticker and the date code on the power cord plug - code is on one of the blades that plugs into the wall. it is stamped into it. We are out the vacuum till the new part gets here, but I have to give them props for great customer service and an easy warranty claim process.e3779990-e534-4036-811a-dd038f1e3c30.jpg
