Dyson DC05 Motor Change

Remember to have the appliance unplugged before attempting this repair.

This is the most involved repair to this machine and should only really be attempted by people who feel confident enough to do it. Please refer to the disclaimer at the very bottom of the page before you start.


Tools needed:

Flat blade screwdrivers (assorted);

T15 Torx screwdriver;

Possibly long nose pliers.


If you need a Torx screwdriver or a new motor, you can get one from here: >>Dyson Cylinder Spares<<.


Possible Symptoms of a Damaged Motor

The things to look out for are:

A strong smell of burning;

The motor may sound laboured;

The motor may make a low, popping, bubbling noise;

Smoke from motor case area;

High pitched noise may indicate motor bearings are worn.

Please Read First

This repair was on a machine that had been repaired by someone else who had removed the cable rewind and replaced the cable without it.

I really wanted to do a guide on how to replace the cable reel on a DC05 but I will have to wait until I get another to repair.

When you come to the part where the wheels need removing, with some models (usually late model DC05 machines), the wheels will simply pull off.

On the earlier models - like the one I have used for this guide - it is a little more tricky.

This guide will also show you how to gain access to the switch, but these rarely need to be replaced.

Please also use caution with the cable reel as it can jump out of its housing and this will cause problems.

Remove the lower filter, if it is badly burnt or blocked please discard and replace. It is always better to replace HEPA filters if they are very black. DO NOT attempt to wash a HEPA filter - it won't work and may damage your new motor.

How to repair a Dyson DC05


This is the stage where the wheels on certain models will pull off.

However, the model in this guide was one where the wheels didn't pull off. In this case, the four screws need to be accessed. They are hidden by the wheels.

Bend the wheel away so the screws can be seen. There are 2x T15 Torx screws on each side.
