Dyson V7 Turning On and Off

If your Dyson is stopping and starting while you're cleaning your home or your Dyson V7 motorhead keeps pulsing, here's how to fix it yourself! 

Why does my Dyson keep cutting out?

A Dyson handheld that keeps cutting out is known as pulsing. A Dyson V7 pulsing problem can be very frustrating! A few reasons why your Dyson is pulsing are potential blockages or problems with the bin or filter. To help you diagnose and fix your Dyson V7 pulsing problem, we have some common causes and fixes below to get your vacuum back up and running. 


Cause 1


When vacuuming throughout your home it's not uncommon that your cleaner will suck up something which may lead to the tool, wand or bin inlet becoming blocked. When this happens you will want to identify and remove the blockages as necessary.

Safety First! Please make sure your appliance is switched off before beginning any maintenance work.

If, while looking for blockages you notice that your cleaning head, wand or bin has seen better days then a replacement will be required.

Cause 2


If the cleaner is pulsing then you may want to try and test your machine with the bin removed.

Removing the bin can help narrow down what could be leading your hoover to turn on and off. If running the vacuum with the bin open leads to the end of the pulsing issue, then you will want to check the bin inlet for blockages and remove any as necessary.

While checking the bin, don't forget to inspect the inlet flap. Using your fingers or a tool you can unblock the flap, and with it in its correct position you can now retest the machine.

If the pulsing has now stopped then you have identified that the fault was with a bin blockage, however if the bin has unfortunately seen better days then you will want to invest in a replacement which can help restore your Dyson.

Cause 3


If your vacuum is still pulsing then you will want to test it with the filter removed.

Remove the filter from the top of the machine and test your hoover, if it continues to turn on and off then the fault could be that the filter is filthy and requires cleaning.

Safety First! Please make sure your appliance is switched off before beginning any maintenance work.

To clean your filter:

  • Wash it with cold water until it runs clear, it is recommended to not use detergents to clean it as this could ultimately damage the filter.
  • Once you have allowed the filter to dry for 24 hours retest your machine.

If the vacuum continues to pulse after the filter has been washed, then the fault could in fact lie with the main body, and a new body would be required in this instance.
