Embedded Dirt Finder green light won't come back on - stays red

I've taken the bottom panel off and looked for blockages, following instructions in the manual, cleaned the brush roll, emptied the dirt cup and can't find anything. The vacuum still has suction and picks up dirt, but something starts to smell after a few minutes of vacuuming. I moved the sensitivity switch from Hi to Reg, and no change. The green light used to come on. I know my carpets didn't suddenly become filthy over night, honest. What can I try next? I

The dirt sensor is a motion detector. After it gets dirty it will either stay red or stay green. You can have the vacuum serviced at your local vac shop and possibly get this fixed. Sometimes they are as good as new and sometimes they are not repairable. It will not effect anything else though.

Try cleaning out all the pathways you can get to. Trapped particles can mess up this indicator. Particularly check the extra mesh filter that is under the bag (there's a plastic grid that snaps over it to hold it into place). Clean that out and make sure the bag is securely in place.

The sensor may be bad, or it may be coated over with dirt. Re,ove the hose at the back of the vacuum, the head of the sensor is down inside that opening, reach in there and clean it off and see it that corrects the problem, if not replace the sensor.

SOURCE: Problem with embedded dirt finder

Take the hose off at the back of the vac, should just turn then pull oull, look down inside the tube that the hose was connected to, there is a sensor there and if it is coated over with dirt, then it can't work, Clean it off and the try it, if it still stays on, then you have a bad sensor, and if this is less then a year old, you have a one year warranty on this. Take it to a warranty shop and take proof of purchase with you.

Hoover Windtunnel Anniversary Self Propelled U6485-900 Embedded dirt finder not working.

The sensor is dirty. The next time you change the bag, leave it off and the cover as well. Plug the sweeper in and turn it on for a few seconds. The lights should blink then run steady. This is the best way to blow out dust. It should be done outside.

Hoover windtunnel dirt finder light stays red. We've cleaned the elbow the roller the hose and have a clean bag. The vacuum is new only had it for 3 months.

I'm not sure about a 3 month old vac, I'd probably go the warranty route. However, for the older vacs thy start getting false positives. The sensor is simply a microphone hooked to a computer chip detecting sounds of dirt entering the bag.
To rig it to start working, you'll need to remove the tool accessory tray and elbow that enters the back of the vac, and attached to the bag. This will reveal the microphone at the elbow, and wire that runs into the bottom area of the vac. When on, a large amount of air comes from the bottom screw and area where the wires enter. My fix was to clean up the microphone contact points a little bit with a screwdriver, and then leave the vac running while putting in dampering in the hole at the bottom, and around the back of the elbow. Cotton balls and electrical tape at the bottom hole, and napkins around the outside of the elbow (wedged between the back of the vac assembly and elbow did the trick). The schematic for the vac is here: http<colon>//www<dot>vacsrus<dot>com/CartGenie/pg_U6485900<dot>asp
Look for micrphone.

Dirt finder sensor stopped working

I had the same problem with a hoover windtunnel 6200 - u5477-900. I removed the flexible hose from top of the plastic tube running vertically along the right side of the back of the vacuum. When I used a flashlight to look into the plastic tube, I could see a clog at the bottom, where the flexible hose curved frontwards towards the brushes. I then removed the 2 screws holding the vertical plastic tube to the vacuum. When I disconnected the plastic tube from the flexible hose at the bottom, I found a clog of dirt and dog hair. After removing the clog and reassembling, the clean / dirty light now moves back and forth from red to green.

Embedded dirt finder light stuck

The Hoover uses a small microphone that is positioned in the plastic housing that the end of the hose fits into, just behind the bag compartment. What happens is that when dirt comes up the hose and hits the 90 degree corner, just before it enters the bag, the microphone picks up the sound and transmits that info to the electonics that controls the lights. Sometimes the microphone will stick and the red light will stay lit. If you take a screwdriver and give the microphone area a sharp tap with the handle of the screwdriver, this will often jar the microphone and it will begin working again. If not, it may need to be replaced. NOTE: this function does not affect the cleaning efficiency of the vacuum. Your vacuum will still work normally whether the dirt sensor is working or not. It is a totally unrelated function to the vacuum itself.
