Vacuum Cleaner Turning On and Off

Have you just started to vacuum your home, only to be left with a cleaner constantly turning on and off? Vacuuming is a chore nobody wants to do, but when one does attempt it the last thing they want is a defective machine. Following this article below we may be able to help you identify the source of your issue. Once diagnosed you may be able to restore your vacuum cleaner and have it cleaning your floors again.

Cause 1


The power cable - without it, the cleaner would not be able to run (unless it is of course wireless). There are only a few offending variables which could cause a fault to the cable and we have detailed them here:
  • If the cable has been pulled.
  • When the cable becomes trapped.
When either of the above happens the cleaner may cut out during use or it can start and stop when the cable moves. This is most likely that the copper wire which resides inside the insulating rubber has become fractured - when this transpires a replacement will be required.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

To be certain, the easiest way of confirming damage to the vacuum cleaner power cord can be done using a multimeter. See our guide on how to use a multimeter here.

  • Open the vacuum and using the multimeter check for a low resistance reading.
  • You need to check the plug connector to where the cable connects inside the machine.
If you have continuity; then carefully flex the wire at the suspected damaged area to check if the connection is broken. If the cable proves to be faulty or has visible damage exhibiting the internal wires then a replacement will be required which can be found here

Cause 2


If your motor is overheating during vacuuming you’ll find that the cleaner will cut out and no longer perform as it should. The motor plays a crucial role in operating the vacuum cleaner; it is important that the motor is kept well maintained for optimum performance. Vacuum motors are cooled down by air passing through them - one of the many reasons to why the motor can overheat is if the filters, pipes or dustbags are blocked.

Blockages can happen from a buildup of dirt and dust, which significantly reduces the cooling process. Here's how you can check your motor for possible defects.

Safety First! Prior to beginning any repair, please disconnect your appliance from the mains.

  • Check and replace any clogged filters and bag.
  • Examine the pipes for any blockages.

If the motor ends up overheating quickly and there is no restriction to the airflow, the problem may be due to the motor being damaged.

If a new motor is required then take a look through our online catalogue for the replacement vacuum cleaner motor you need.

Cause 3

Blocked Filters

If your vacuum motor appears to cut out when it’s warm for a few minutes before restarting, it may be due to the motor overheating. This may be caused by blocked filters. They can become clogged over time from a buildup of dust molecules, preventing less or no cool air to flow into the motor.

Filters are designed to trap dust and pollen particles from the air flowing through the vacuum. Follow our simple tips below to unclog your filters and get your vacuum cleaner performing as it should.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

Remove any excess dust from the filter by simply tapping the filter.

  • If the filter is washable, run it under the tap for a thorough clean.

To prevent the motor from overheating, consider replacing the filters regularly as this will preserve the longevity of your vacuum cleaner. If you’re in need of a new filter, check out our online catalogue for the perfect replacement.
