How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
The brush is jammed
Should the red warning light appear as shown (see above picture) the brush jammed warning alarm has activated as the brush bar is not spinning freely.
Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
If the brush bar jams during use, the AirRAM will stop and the LEDs will appear red. You will need to remove and clean the brush bar (see page 11). The AirRAM will not re-start until the red lights go out.
If the indicator light is flashing red, the thermostat is overheating. To reset the thermostat, turn off and unplug the vacuum. Empty the dust cup and filter and assure there are no blockages in the hose. Allow the vacuum to cool for at least 45 minutes before turning it back on.
Blockages or dirty filters may cause this to happen, the safety cut off will activate and switch off the electrical supply. If the cleaner has cut out, simply unplug and check for a blockage or dirty filters.
If your vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.
A strong odor from the shellac that coats the copper coil windings is an indicator that the motor is about to or has burnt out. If the motor is still running, even if it turns on and off by itself as it is heating and cooling, you can still run the motor until it gives up for good.
For best results the filters can be washed in warm water but check they are thoroughly dry before putting them back into place, this may take up to 24 hours. Hoover recommend that you fit new filters once per year to keep your vacuum cleaner in tip top working order.
Rinse the filter
Any fine dust remaining in the filter can usually be removed with a gentle rinse under a cold tap – hold the filter under the running water until the water runs clear. You shouldn`t need to use any detergent – just water.
A red light comes on to indicate fast charging of the battery. After fast charge is done, the light turns green and the remaining 3 hour charge becomes a trickle charge, optimizing battery performance.
That`s the Security Indicator Light , and it`s blinking, it`s telling you that the car`s security sytem is armed. When the car is locked and off, the Security Indicator Light will blink steadily. It will trigger shortly after the engine has been turned off and the key has been removed from the ignition.

The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
A thermal cut off is a heat-sensitive device that automatically disconnects the power to a vacuum`s motor when the operating temperature exceeds a safe value.
NOTE: When the charging indicator light is flashing red during use, it means the battery is running low and requires charging.

Dirt finder I have a Hoover U6439-900. After the cleaner was used a few times, the dirt finder light cycles between green and red on the regular setting and will not go to green. On the sensitive setting, the red light stays on most of the time. I have tried to run the cleaner to remove any dirt but have not solved the problem.
ANSWER : 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.

Hoover – Red Light Dirt Sensor
ANSWER : 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,

Hoover wind tunnel the red light dirt finder stays on
ANSWER : There’s a microphone inside the tube the dirt runs up. It listens for dirt coming up the tube. They just go bad and there’s no making it better. You can either replace that entire assembly or ignore it. Fairly easy to replace. I’ll include the part so you know what you’re looking at.
Good luck! The Vac Dr.
