Is there a small LED light illuminated where the low voltage wires connect to the main unit? There may be a small rubber boot covering the connection and the light. Just slide it back, and there should be a green LED light if the unit has power. If the LED is not on, there is no power to the unit (tripped breaker, plug came loose from electrical outlet, etc.) If LED is illuminated, short across the pins where the low voltage wires connect to the main unit. (These will be small 18-22 gauge wires, not the larger electrical cable!) You can do this with a coin. (Don't worry, it's just 24 volts and you won't even feel it) The unit should come on. If it doesn't, and you have light from the LED, then it's probably the relay on the board inside the unit, or the motor. Good Luck!

There is two possible causes. One you could be plugging in the end of the hose wrong. Make sure the hose end is securely in and in the right position. Second it could be a malfunctioning switch in your handle. Here is a site with a variety of different hose handle switches.

The power switch may need to be replaced. Call the Dyson helpline - they will give you the location of an authorized Dyson dealer in your area who will be able to replace the switch.

Start with this. Unplug the vac to shut off, then disconnect the low voltage wiring at the vac.Plug the vac back in. If the vac still runs you have an internal short on the relay or wiring inside the vac.
If the vac stops then the vac and final wiring is OK and the problem is in the wiring in the house.
Have you removed any inlets for painting or had any renos done or pictures hung. If so undo what you did last. If inlets were disturbed remove them and look for low voltage vac wires touching metal backing plates in the wall or touching the inlet mounting screws.
If you have done a reno or hung pictures you may have pierece the wire for the vac creating a low voltage short which will keep the vac running until removed. I have seen this happen with freshly installed 1/4 round molding along a baseboard

If there is a switch on your hose, it may be broken.
Your system powers on from the inlets via two low voltage wires that run from the inlets to the switch/relay at the power unit. Each inlet has 2 spring loaded pins attached to the low voltage wires. In the photo below you should see these pins at the bottom of the opening, just above the door hinge. The receptacle at the top of the inlet in this photo supplies 110 volts to power your power nozzle. Not all inlets have this option, but if yours does, exercise extreme caution. Your hose must have a completely metal end or if it is a plastic end, it must have a metal band in order to short the 2 low voltage wires together to trigger the switch.
You can manually short the two low voltage pins together by using a metal pipe or needle nose pliers, just touch both pins at the same time. CAUTION: stay away from the 110 volt receptacle if present.
If your system powers on with this manual method then it would seem that the problem is in your hose.
If your system does not power on; your low voltage wires may be disconnected from the power unit or disconnected somewhere else . It's also possible that you have a bad circuit/controller board in the power unit.
