It indicates that the insulation for the wires is melting from overheating wires
stop using it and take it in to an appliance repair shop for an inspection and proper diagnosis
if it is still under warranty take it to an authorized service agent

My dyson dc28 brush stopped turning after a pop and smoked. Smelled like burnt plastic. The attachment hose still has suction and is working fine. What happened?


When an object gets under the machine it can
cause the brushbar to suddenly jam. The belt between the motir
and the brushbar however is forced to keep turning
causing the rubber belt to burn an then break.

Smoking and smells bad

This is generally a sign that the motor has burnt out. With spendy vacuums like Dyson, it's often worthwhile replacing the motor rather than the entire vacuum.

My dyson dc07 has started to smell a bit of burning.

This will be 1 of 2 problems.

1. If its a burnt rubber smell then its the belt that has gone and will need to be replaced.
2. If its a metalic smell then your motor is burnt out.

Replacing the belt is easy enough, the motor is a lot more complicated and should be left for an expert.

On turning on different noise then noticed smell of burning then just stopped working and no power since. DC 07 Dyson.

Unfortunately your motor had burnt up..most times this is due to not cleaning or replacing the filters...the filters get dirty and the motor gets no airflow to cool it....very common on dyson vacs

Turns on, brush rotates, but no suction.

the only thing i know about vacs is if there is no suction its blocked might have sucked up a piece of plastic bag and wraped around the fan hence no air or the screw that holds the fan has come loose take your filters out and turn on you may have sucked up fluid and not known it hence filters are blocked also brushes may seem alright but may be worn under half there fore springs are not at right tentsion if your armiture is black where the brushes run on may not be getting a good contact or if it smells burnt good chance you burnt it out then theres the power switch test with multi tester the check for loose terminals then test the field coils are correct ohms as well
