How to Identify and Fix Common Vacuum Problems ?

If the vacuum cleaner stops suddenly, the filters should be checked to make sure that they are not blocked or that they require changing. This applies to both bagged and bagless models. Also check if the nozzle or hose are blocked.
If the unit runs for a few minutes then shuts off, the motor needs to be replaced. Central vacuum motors generally last for 800-1100 working hours. If your motor has run less than 800 hours or activates by jolting the canister, it may be possible to extend the life of the motor by replacing the carbon motor brushes.
Q: My Electrolux Central Vacuum has low suction? A: This is probably a clog within your central vacuum pipe. You should contact a local Electrolux central vacuum repair technician to get the clog out without any damage.
To use the system, you simply plug a portable hose into one of the wall- or floor-mounted inlets, which is connected to the motor via a network of PVC pipes snaking through the walls and floors. That signals the vacuum to turn on.
This can be caused by a clogged water inlet valve, the main water supply valve being partially closed, or low water supply pressure from the home.
If your vacuum was working fine and then suddenly shut off, it may have overheated. Most vacuums are equipped with a thermal protector safety switch that won`t allow the motor to run when it becomes overheated. You will need to wait for 30 minutes to 2 hours, depending on your machine, to try again.
If the filter bag or canister is too full, it cannot pick up any additional particles and will simply jam or the motor will overheat and shut down. So, when you suspect your unit is about 75 per cent full, empty it! Don`t wait until it`s packed to the brim, clean it out and prevent the breakdown.
Clog located in the vacuum hose
Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.
Ducted vacuum cleaners filter exhaust into a location outside of the living area of the home, such as the garage. By filtering exhaust outside of the living area, ducted vacuums reduce allergens, dust, and dirt inside the home, creating a cleaner air environment for all the occupants.
The suction motor creates vacuum pressure and suction by rotating a motor fan. The impeller rotates at an incredibly high speed of about 30,000 to 35,000 RPM. A suction motor`s power is measured by multiplying the rate of air flow and the vacuum pressure, which induces air flow from the brush through the hose.
Some of the most common faults that will make your washer stop mid cycle include thermostat failure, problems filling up with water for the rinse cycle, or even pump problems that prevent your washer from draining. One thing that you can check yourself is the lid switch.
The machine will automatically shut down when it senses the load is out of balance to prevent mechanical damage. Turn the washer off and re-balance the load by moving the clothes to an equal distribution. When you close the lid, spinning should resume.
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.
If you find that your machine is turning off intermittently, the filter in your vacuum is most likely full and covering the ventilation system. Remove the filter, then empty and wash it. Allow the filter to dry for at least 24 hours, or until it is completely dry.
One of the first things to do when your Dyson vacuum cleaner keeps starting and stopping is to empty the bin. It may be full, or the machine may simply perceive it as too full to continue working. Dyson vacuum cleaners require constant airflow through them to work, and a full bin can stop this from happening.
A vacuum cleaner can run continuously for 30 – 60 min each time. The vacuum cleaner has no suction power. For example, a hair cannot be sucked up.
If you don`t vacuum your carpet, the dirt will break down carpet fibers and create a breeding ground for dust mites and bacteria. In addition, your home will begin to smell musty from the dirt, mites, and other organisms settling into the fibers.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
Burning smell can indicate motor damage
If you suspect that the motor is damaged, you should not continue to use the vacuum cleaner! The cause of motor damage is usually wear and tear or damage caused by prolonged improper use (e.g. overheating). In most cases, it is not worth repairing.
The most common problem with a vacuum cleaner is also the easiest to remedy: clogs in the hose or attachments. Also the electrical cord, motor, switch, fan, brushes, and motor bearings can all need repair or replacement. The drive belt may need replacing; and the attachments, hoses, and filters may need unclogging.
The two main indicators to determine vacuum power performance are water lift and airflow. The water lift is measured in mmH2O, mbar or kPa. It represents the suction force and is the reference parameter for vacuuming liquids and heavy materials. The airflow is measured in m3/h or in l/s.
The suction power is measured in Watt (W) and is typically between 250 W and 450 W for machines with 1 motor. The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle).
Any negative pressure significantly below standard atmospheric pressure (760 Torr/mmHg, 29.9 inHg or 14.7 PSI) is considered a vacuum.
Vacuum means the absence of all matter including air. As there is no air in the vacuum, air pressure will be zero.
