My SEBO Powerhead keeps cutting out while in use momentarily & the Power Brush Control Lights come on.?

Must likely there is a switch that is just dirty,(mounted on #31) that is activated when you the elbow is is down and when it is in the upright position. You will have to take the back end cover off to get to it and blow it out to clean it. Could also be the wires in the elbow, or where it hooks up to the wand and hose.

The full bag light comes on when it is getting full or a blockage in the hose or the dirt inlet by the brush roll. Other then that, there is a circuit board called the computer controller, part #5740ER and is giving you a false reading and causing a shut down.

I've had my Hoover S3755 for about 2 years and loved it, at least until the last couple of months when the "belt slipping off" problem started. I changed the belt and the vacuum would work for a little while then the belt would come off again. I put on a new belt again and within minutes the belt had slipped off. I took it to my local vacuum repair about 4:00 in the afternoon. By 4:45 I got a call from the repairman that he'd fixed my vacuum! What did he do? He put a different belt on it. He put a Rainbow belt on my Hoover that's thicker and doesn't have as much "give" as the Hoover belt. It's also a little bit wider than the Hoover belt. Now when the brush slows or stops at a carpet edge the belt doesn't slide off.

Sorry you've had to wait so long for a reply. Perhaps you no longer need help, but here goes anyway. Must confess I'm not certain about this, but my guess is that the automatic height adjust mechanism (let's call it the HAM for convenience) isn't working properly. The HAM works by sensing the drag of the brush roll against the carpet, and raising or lowering the front of the machine as necessary to maintain constant drag. So first you need to check the HAM, as follows: with the handle in the locked upright position, switch on and wait for a few seconds (there may or may not be any signal from the green UP or DOWN lights). Then, still switched on, lower the handle to the normal operating position and check that the green DOWN light comes on. Wait until the DOWN light goes off and then return the handle to fully upright (switched on all the time). When fully upright the UP light should come on for a few seconds and you may be able to see the handle tilt backwards as the front of the machine rises. If this is all working properly, we need to look elsewhere for a solution. The next thing I would look for is for a broken belt. Just turn the machine over while it's running and look to see that the brush is rotating (keeping fingers and clothing well clear, of course). Sebo belts usually last 15 years or more, but breakages are not unknown.
I realise this may not exactly solve your problem, but it should give you something to work on. If you need more help, post a reply here, saying what you've found so far, and I'll try to be more specific.
Good luck!

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
