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 some models (usually late) the wheels will simply pull off.
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.
First job is to remove the hose.
Unclip the lid.
Remove dust bin.
Remove washable filter
Unlatch the lower filter cover.
This is the lower filer with the cover removed
Remove the lower filter, if it is badly burnt or blocked please disgard and replace
Remove the rubber bumper.
This elbow where the hose joins needs to be pulled off.
It requires some effort but just pull it straight up, using leverage with a screwdrive may damage the plastic and so is not recommended.
This is what it looks like removed
The button below the elbow can now be removed, use a screwdriver and be carefull not to snap the lugs
Carefully remove the button
The button on the other side also needs removing carefully prise it off.
And here it is removed
Now remove the lid carefully with screwdriver by gently prising the lugs either side outwards
Remove the lid
This is the stage where the wheels on certain models will pull off.
However the model in this guide wheels didnt pull off and the 4 screws need to be accessed that are hidden by the wheels
Bend the wheel away so the screws can be seen there are 2x T15 torx screws on each side
Sometimes jamming a pair of pliers into the gap is helpfull.
With the 4 screws removed the last screw in the hole arrowed needs removing.
Lift the top off
Remove the motor body
(The cable on this model is missing in this photo)
The motor is inside the case .
The fourlugs need unclipping all the way round and this will remove the lid.
The lid has been removed and the rubber motor mount can now be seen
Pull the motor mount off and the motor can be accessed
This motor has overheated and burned the armature
If you didnt pull your wheels off earlier ignore these 3 steps
If you have a plastic insert on the wheels knock it through with a screwdriver from the inside
Pull the plastic insert out
The wheels will pull off the chassis really easily now.
The wheels do not have to be removed but it is a lot easier if they are.
Back to the motor. Put the top rubber mount from the old motor onto the new motor
Now push this rubber grommet through the motor case, this will make refitting the motor a lot easier.
Connect the wires.
These two pins arrowed
Locate into these two holes arrowed
Push the motor into the housing gently make sure the holes and pins are alligned and dont forget to pull the grommet back and make sure it is in its correct position
Snap the lid back
Sit the motor casing into the lower chassis.
The upper chassis needs to hook over the round part and gently lower into position
Check all the way round that the two halves are sat snug with no gaps
When happy refit the 5 torx screws
Now push the wheels back on
Push the plastic pegs back (if applicable)
Push the buttons back
They shoud snap back
Push the elbow back onto its mounting
Refit the lid
Refit lower filter.
When refitting the filter lid make sure the lid latches are sat in the correct position
It will snap back in place
Refit washable filter
Refit rubber bumper
Refit bin and hose and test
Please remember to PAT test your appliance after repair and if in any doubt get a professional to do it.
