Dyson V11 Outsize is pulsing on Eco and Mid mode, but works fine on boost mode - Ideas? | Dyson Community

My Dyson V11 Outsize has started pulsing on eco and medium mode then stops, but works ok when I switch it to boost mode. I checked for all possible blockages, also changed filter to brand new, but still problem exists. I have 3 different heads and it does it with any of the heads.

I read that the fix for this is a main body. It is apparently an electronic failure that has happened with other units in the past and Dyson is aware of this issue. I also read that Dyson has given a new main body for free in the past and it solved the problem, even though the vac was 7 months out of warranty.

Has anyone else had this issue, or aware how I can get Dyson to attend to this issue ?

Thanks

The pulsating issue does occur due to blockages or it can be due dust being stuck in the cyclone.

My cordless vacuum cleaner is making a pulsing noise or switching off after a few seconds of use, what does this mean? | Dyson Community

Thanks for your input everyone. I have been in contact with customer service. They asked for a short video of the problem and have verified the fault is in the main body. They are sending a replacement main body.
