Stops working after about 5 minutes. leave for 20 and it starts again for a while.

Hi,

Did the vacuum just stop dead while you were using it? The vacuum contains a thermal-fuse which will cut the power off if it gets too hot. Unplug it and leave to cool for 10-20 minutes and then try it again.

If the vacuum has already been allowed to cool and there is no power, there are many possible faults including the power switch, motor and thermal fuse. In order to determine where the fault is, you will need an ohm-meter / multi-meter.

If you've allowed the vacuum to cool and it's still dead, please post back for further assistance and let me know whether you have any electrical test equipment.

If you can't smell burning then it's probably a broken power switch or the vacuum got too hot and the thermal overload protection has tripped. Try leaving it off for 15-30 minutes and try it again. The thermal overload will reset itself during this time and it should work again.

In the meantime, make sure you have power to the vacuum, check for any blockages and check that the rollers in the cleaning head will turn by hand. Also, give your filters a clean. Any of these could cause the vacuum to overheat.

If you've already done this and/or power doesn't return after 15-30 minutes, I would start by checking the switch.

A couple of questions . . .

1. Does the power switch feel "normal" - basically does it have a positive feel when you switch on and off?
2. How long had you been using the vacuum before it stopped working?

i had a similar thing happen and just got off the phone with dyson. there is a resettable switch on the handle. they told me to start the vacuum in the upright position, put it in the non upright position, then push and hold in the beater bar switch which is located next to the on/off button for 10 seconds and the beater bar should start to function once again

its overheating check to see if its cloged any where look behind brush roller

It may have a problem of overheating. If you havn't cleaned out the thing that holds all the dirt and dust, you may want to consider doing that. There might be a thermostat in it that shuts down whenever it thinks it's to hot.

sounds like the motor is overheating .check and see if the brush roller is turning when its on.if its hard to turn or won't turn at all take it back where you bought it and insist on a new one.my thoughts on new items is if you buy something new then it shouldn't have to be fixed.insist on it.please leave feedback...pete

The problem is definetly the motor. make sure the filter is not covered in the hair, if not you need a new motor. i fixed plenty of them.

you forgot to say if it is a 3 phase machine
if it is 3 phase then a phase in the unit is overheating and that will stop the machine then blow the breaker as all phases have to draw equal current
if it is a single phase then the start/ run capacitor or centrifugal start run points are not breaking at speed and so the start windings are overheating and causing the breaker to trip
Take it to an electrical motor rewind shop and have it properly tested with test equipment

This is from the Dyson web page:
Get expert help Thermal cut out Most Dyson vacuums have a built in safety system that stops the machine if it begins to overheat. This usually happens because the filter needs washing or your machine is blocked. If your machine turns off on its own, unplug it and leave it for at least an hour to cool down. Remember to check the filter and look for blockages before re-starting.
Any non- domestic use may adversely affect the filter performance such as vacuuming up plaster dust.


Sounds like your vacuum is overheating. Check the above.
