Problem with embedded dirt finder

I just got this vacuum today and found that no matter how many times I went over the same spot, the embedded dirt sensor stayed red.  Can you tell me if there could be something else wrong besides a dirty carpet???

    Ditto yep; just got it for Christmas. It worked OK for a couple of days, but now will not go green under any circumstances.

    Disappointed

    Have had the vacuum less than a year and is starting to do the same thing. No matter how much I vacuum the light stays red.

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.

Embedded light sensor stays red all the time


The back cover is called the a micro/dust assembly. See #21 here:
http://www.ereplacementparts.com/hoover-u6630900-windtunnel-selfpropelled-bagless-vacuum-parts-c-37315_37337_37584.html


The little sensor should be in the round recess in the top of that assembly. When you are putting the cover back on you have to use a pair of needle nose pliers to push the sensor into the round recess until it is snug. It is hard to do because the wires to the sensor are very short and you have to be careful not to break the wires on the sensor. The sensor is a little microphone that senses the noise of the dirt going through the EDF. The first time I did mine I didn't push it in hard enough and came out of the EDF recess and fell inside the vacuum body.

Hoover - Red Light Dirt Sensor


check to make sure the settings didn't get inadvertently switched to the hi position, move the switch back and forth from high to reg a few times, then leave it on reg.

remove and hand wash the primary filter and secondary filter, dry throughly and replace them in the vacuum.

if none of this works, you will need to have the vacuum serviced, or if it is still working, just don't pay attention to the dirt-finder. the dirt sensor on your vacuum is located in the suction tube and is generally not accessible enough to clean without taking the vacuum apart.

hope this helps,

Kenmore Progressive issue


I started by replacing the bag. No change.

I opened the bag compartment and noticed that the dirt sensor went to clean, but only when the compartment was open.

I cleaned out the foam filer at the bottom of the bag compartment. No change.

I took off the air outflow filter and cleaned it (Should have replaced it, but don't have a spare right now.). No change.

Unscrewed the hos from the back of the vacuum. The dirt sensor again went to clean.

I had isolated the problem to the hose. I hooked the hose back up and the dirt sensor went to dirty again.
The problem was that the hose was dirty on the inside. To clean the hose, I stretched it out little by little and banged it a little to loosed the dirt with the vacuum running. After the hose was cleaned, the dirt sensor had no problems.

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.

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.

Dirt finder


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.

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


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.
