Red light comes on after vacuum is running

Try running a phial of Kalstop through the boiler to descale the boiler unit. Calicification in the boiler and on the controlling solenoid can cause the unit not to produce steam. My boiler unit was so corroded that I had to get the boiler container completly replaced.

Hi There,

So when this light is displaying, it's says "Bag Full or Clog" on the indicator. If you have changed the bag, and it's still showing this light, it means that you either have a clog in the vacuum, or your filters are dirty, which is reducing the suction and making the machine think that your bag is full. If your machine is actually cutting off, this indicates that your machine is definitely clogged, or something is stuck inside which is causing the motor to not get air flow, and cauing the machine to over heat. When it shuts off like this, it's a protection system that prevents any damage from happening to the motor when it can't breathe and starts to overheat.

My guess is that there is probably a clog in the machine somewhere, or the filters are dirty. Here's what you may do to diagnosis the machine, and try to isolate the clog to find out where it is in the vacuum.

Step 1. Remove the hose and wand assembly from the vacuum cleaner completely. You may do this by pressing the two tabs on the end of the hose that plugs into the vacuum cleaner:



With the hose and the wand removed from the vacuum, it should look like this:


Step 2. Now turn the vacuum cleaner on and check to see if the red light comes on while the hose and the wand have been removed. If the light comes on, then this indicates that your filter is dirty (or the PCB electric board is bad if the filter is clean) and needs to be replaced.

Step 2. Re-attach the hose and wand back on the vacuum, but just the end of the hose that goes into the vacuum cleaner, leave the wand out of the vacuum cleaner so it looks like this:



Turn the machine on now as if you were using the attachment hose to clean corners or above the floor and see if the red light comes on here. Also listen to the noise the motor makes and see if the noise changes when you put the hose back on the vacuum cleaner. If the red light appears, or if the motor makes a higher pitched noise now, then this indicates that you have a clog in your hose or wand. You may verify this by remove the hose again from the vacuum, and also removing the wand from the hose by pressing the hose release button on the wand and pulling the hose out of the wand. Look down both of the parts and see if you can see thru both sides. If you're not able to see light through the hose, or the wand, this indicates this is where the clog is. You may take a metal clothes hanger, and try removing the clog this way.

Step 3. If the red light did not display with the wand not inserted into the vacuum, put the wand back into the vacuum cleaner as if you were vacuuming the floors:



Turn the machine on, and see if the red light comes on in this position. If the light does come on, then this indicates that you have a clog in the bottom of the vacuum cleaner. To check and see the clog in the bottom of the machine, I find it easiest to remove the upper bag housing from the vacuum cleaner completely so you're just looking at the bottom power nozzle of the vacuum cleaner. There's a button at the bottom of the machine that is either a grey, or yellow color depending on what color your vacuum is. Simply press this button in, and lift upwards on the handle or the bag housing at the same time:



Step 4. After the bag housing has been removed, turn the lower part of the vacuum upside down so the brushes are facing upwards. There's a little orange flap on the bottom of the machine that is actually a clog port. Almost every time there is a clog in a Sebo, this is where I typically find the clog. Open up this orange colored trap door, and look to see if you can see any obstruction or clog underneath of here:



Step 5. You may rotate the neck of the power nozzle part towards you so that you may look inside to see if you see any obstructions inside:


Step 5. You may also remove the brushes from the vacuum and look behind the brushes at the suction port, or the area where the suction goes through the vacuum to see if you see anything obstructing the suction here.

These are really the only places that the Sebo can get clogged. If you checked all of these areas, and the red light is still displaying, this means that your PC Board that controls this indicator has gone bad, and needs to be replaced. If this is the case, please just reply to this repair using the comment field, and I'll be more then happy to help you through the replacement of replacing the PCB Board.

I hope this answer was helpful to you, and you were able to find the clog and fix the problem.

Thank you so much,

I had the same problem. Red light would come on after charging was complete. On investigation I found that there is a small gray wire that runs from the rear batteries to a large solder spot on the control board. Upon re-soldering this wire I got an additional 3 V of power and the red light does not come on anymore after it is charged. I can vacuum the whole house and then some and still not run the batteries down.

If you have one of your red lights flashing or on all the time that will indicate where you need to look for your repair. Beater bar light will indicate a brush roll replacement and the bag light indicates a need to empty the bag or look for a clog somewhere in the air flow area of the hose or wand. These machines are designed to shut down if you keep trying to run them with a red light coming on.

I have a Silver Moon S558, when I turn it on the power light comes on and a few secords later the red warning light comes on. What is causing the vacuum not to work? One day I was vacuuming, turned it off and a few minutes later went to turn it on and nothing, but these lights turning on. Is there a fix?

If the bag full light keeps coming on, you can first try adjusting the dial on top of the vacuum cleaner. If that does not work, then you need to change the control valve. This is an internal component of the canister and is directly below the dial. You will need to follow the instructions on a previous post to open the Electrolux plastic canister vacuum, and remove the bage cage. Once you remove the bage cage you can change the control valve, and this will solve your problem with the bag full indicator.

the plug light should be on, so you know its getting power. it might just be a broken switch, or worst case a bad motor. a good vacuum repair should should be able to check it out at little to no charge before you agree to any repair.

I did the same thing,I charged for over 12 hrs and it run for only few seconds then the red lights comes on.I was on the process of replacing with a new battery till I got in to this and I guess I'll leave it alone rather than wasting money for a new battery.

Does it do this with the hose off? If it only does it when the hose is hooked up to it, then you have a clog in the hose.
