We have a dyson root cyclone and it shuts off after a about 5 minutes of running. Then after about 10 minutes it will run again.

sounds like you have a clog some where or need to replace your filters. your machine is tripping the thermal switch thats why it only runs for 15 min

Hi Emmeline,

I'm sorry to hear you're having difficulties with your DC17. From what you've described, it sounds as if the thermal cutout feature is shutting the machine down to prevent overheating. If you've already tried washing the filter and are still experiencing the issue, I'd encourage you stop using the cleaner and to contact us directly so we can help. You can call us free on 1866MYDYSON, or email [email protected]. We'll look forward to hearing from you.

Kind regards,

Jack

Your battery is losing voltage too quick. It has probably developed a 'memory'. Dyson claims that their handheld has the best suction out of all the handhelds out there. In order to maintain that claim the circuit board will shut off power to the motor when the voltage drops below adequate charge for full suction.
We need someone who can teach us to bypass that part of the circuit so it won't cut power to the motor or you need to get a new battery.
Shorting the battery like an Aircraft battery then re-charging won't fix it.

REMOVE AND CLEAN FILTERS AND YOU MAY FIND IT WILL WORK OK IF STILL CUTS OUT YOU MAY HAVE A FAULTY THERMAL CUT OUT BLOCK INSIDE THE MOTOR HOUSING
THIS HAPENS WHEN DYSON IS USED WITH CLOGGED FILTERS AND HEAT DAMAGE TO THERMAL BLOCK

AVERAGE REPAIR COST £45 - £ 69 FOR NEW REPLACEMENT

have a look at the filters first as it sounds like you blokeage

Dear Michael_Stad,

I am going to sound like a broken record but here is my same answer to another person with the same problem.

I have I had the same problem with my Dyson DC16, where it only runs for a few seconds at a time with each trigger pull. My husband called Dyson (Canada) and without hassle they shipped us a replacement part which I just received this morning. The replacement part sent to us is: DC16 Main Body with Rating Plate. It is also under warranty for 1 year. The great customer service makes up for the flaw in the machine. Also, Dyson is aware of the problem. Hope this helps.

there is a moving part, like a bearing that seizes up when warm. may be the motor bearing, unit will have to be taken apart and inspected

Check battery maybe is old or not correctly charged.
