Machine cut out during use. Most
Dyson vacuums have a built in safety system that
stops the machine if it begins to overheat. This usually happens because the machine or tools are blocked. If your machine cuts out, unplug it and leave it for at least an hour to cool down.
Dyson vacuums purchased in other markets may not include a
fuse within the plug. However, most
Dyson vacuums are protected by a thermostat engineered to shut the machine off for protection if it starts to overheat. ... The
vacuum shouldreset automatically after it's
had at least 1-2 hours to cool down.
