If this just happened, tho I see by your posting it was over an hour ago... sometimes the thermal reset there has tripped off and needs for it to cool down. The other thing is there is a reset button on the unit itself that should be pushed in for it to reset.

if all of that is ok, try the manual switch on the side of the unit. It should work and if the unit is less than 5 years old it should be under warranty as well. So no cost for a fix.

Good luck.

Bag shows full when it's empty. No clog in the hose, but when I start to vacuum, the bag-full indicates FULL, even though it's a new bag.


See if there are any sponge filters that might be clogged. They're usually between the bag and the air flow going to the motor.

I have the Miele cat & dog S5000 vacuum. I have had it about 1 year and lately the suction doesn't seem as strong and the full bag indicater is always full. I have followed instructions in manual but...


Greetings,

I would say that you have a slight clog in the hose or in the power nozzle somewhere. The full bag indicator is just a guage that will indicate full when it feels like it's lost suction. Example: If you were to take the hose and cover it with your hand, you'll notice that bag full indicator will show full.

To check and see where the clog in the vacuum is, remove the wands and floor attachment so you just have the hose on the vacuum cleaner. With just the hose attached, turn the vacuum cleaner on. Does it still show a full bag? If yes, then remove the hose completely from the vacuum cleaner so it's just the canister part by itself and turn on the vacuum again. If the bag full indicator is now showing an empty bag, this means that you have a clog in your hose.

If the bag full indicator displayed an empty bag when you had the hose on the vacuum, but shows a full bag when you have the wands and floor tool attached, this means that you have a clog in the vacuum either in the wands, or the floor attachment.

For removing clogs from the hose, the quickest way is to just purchase a plumbers snake at your local hardware store, and run the snake through the hose until you find the clog. You may also take a high pressure hose and spray it down the hose until the clog is cleared, but if you use a water hose, MAKE SURE the hose is 100% dry before you use it again.

Also that bag full indicator can be adjusted if you are getting a lot of suction power and it still shows full.

I hope that these suggestions helped you diagnosis your Miele canister to figure out why the indicator showed full. If this helped you please rate my repair helpful.

Feel free to contact me if you need further assitance, I'm always happy to help.

The bag indicator shows full but the bag is empty


In my bag vac, I have found that when the light shows the bag is full when its not that there is something between where it sucks into the vac to where it empties into the bag...maybe cat hair, dog hair....etc. Try removing the bag and running it, this may allow the air to flow alittle faster and force out the jam. You may also try removing the bottom of the vac, usually just a few screws, and checking to see if you can see the jam. What is happening is this jam is slowing down the air flow and the vac thinks the bag is full....also check the filter where the air leaves the bag area...also look where the bag connects, sometimes trash can hang there.....good luck

Bag change indicater staying on and vacuum smells hot when using


I suspect there is a blockage somewhere along the pipes leading to the dust bag.
The bag full or bag change indicator measures how strong a vacuum is present at or near to the point where the bag is connected to the pipes. Under normal conditions an empty bag poses little resistance to the air passing through and therefore causes only a slight vacuum. A full bag poses a lot of resistance and therefore causes a strong vacuum which in turn makes the indicator show time to change.
If, however, there is a blockage somewhere, regardless of the state of the bag, a strong vacuum develops which causes the indicator to show as if the bag is full.
The hot smell is proably a result of the motor having to work hard trying to overcome the blockage.
Try to look into all the pipes - you may need to do a bit of dismantling and/or strech out flexible pipes to do so - to see if there's anything stuck. Also try some (careful and gentle !) poking through the pipes with something like an un-ravelled wire coat hanger, but take great care when poking through the flexible pipes as these can be ripped and then you'll have a differnt problem !

13 yr Electrlux.Cuts off if hose plugs in.Says Bag Full-bag empty


This sounds like the valve assembly (full bag control) is faulty or one ov the tubes is clogged. You will have to take it to the shop.

13 yr Electrlux.Cuts off if hose plugs in.Says Bag Full-bag empty


sounds like you have the plastic bodied canister. the controll valve inside is bad. I usually just disconnect those to avoid future problems. you may want to take the vacuum to a repair shop though becuase they are a pain to get apart and get back in one piece.

Electrolux Epic 6500SR Full Bag sensor working, Does not Reset properly


The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.

Full bag system works properly, but doesn't reset easily


Either there is something wrong with your switch. Which it doesnt sound like it. Take it to your dealer or call another one it sounds like the control valve needs to be replaced. I am a dealer 1-866-966-9350.

Empty bag shows as Full


You have a clog, either in the hose, the dirt inlet by the brush roll or the filters are clogged.
