No power
Before completing these checks it is important to determine whether or not the thermal cut-out has activated- was the
machine in use when the power stopped?
The appliance has a non-self resetting thermal cut out safety device to prevent overheating. If the appliance cuts out, unplug
it from the mains supply socket and leave it to cool.
Caution: In order to avoid a hazard due to inadvertently resetting the thermal cut-out, the appliance must not be supplied
through an external switching device (e.g. a timer) or connected to a circuit that is regularly switched on and off by the utility
company, or plugged into any socket where the electrical supply is unstable or likely to be turned off.
Note: If the customer advises you the machine was working intermittently - cutting in and out as the appliance is
moved back and forth/up and down - arrange a repair, as this may indicate a power cord problem. Also advise
the customer not to use the machine until a repair has been carried out.
Make sure the customer’s home has
power. Check trip switch and fuse
box.
With the exception of the power fuse needing changing or a problem related to the power supply in the customer’s home, if
the fault is any of the above, arrange a repair.
Note: The Dyson guarantee does not cover accidental damage to the power cord and plug.
Important advice
CAUTION: if the fault is related to any electrical or mechanical issues, please ask the customer
not to use the appliance until a repair has been carried out.
Ask the customer to
unplug the machine.

US only:
The machine has a reset and test button built into the plug. This protective device (ALCI- Appliance Leakage Circuit
Interrupter) should be operated each time the machine is plugged in and used.
To test: press the test button. The reset button will pop out, indicating that the machine is safe to use.
To reset: unplug the machine and press the reset button. Plug in again to use your machine.
If the ALCI trips while in use, the machine should be unplugged. Press the reset button and reinsert the plug into the outlet. If
the ALCI immediately trips for a second time, unplug the machine and arrange a repair.
