My DCO7 keeps cutting out, all filters are clean, it was my mother ln laws she gave it to me, I thought I could solve the problem, there is no suction from the hose, I am now frustrated. Regards steven smith

The electric motor inside your Dyson has a built in over-current trip to protect itself (and you if it seriously overheated and caught fire). This normally automatically resets itself, however if the motor has just about had it, next time it is switched on it just trips again.

The primary cause of motors overheating is that the filters are not cleaned or replaced frequently enough. Dont be fooled by Dyson's "lifetime filters". They need to be regularly cleaned and replaced when necessary.

Replacement motors are available on eBay for about £25, however replacing one requires good DIY skills and tools.

Have a look at www.dysonmedic.com and see if you feel you can tackle it yourself. If not, take it to a repair shop or call the Dyson helpline.
