Remember to have the appliance unplugged before attempting this repair
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.
Tools needed and other information
A T15 torx screwdriver is needed for the screws
Large flat blade screwdriver for the retainers on the soleplate.
This repair was carried out on a silver and grey machine these have a single belt.
Repairs to dual belt machines are similar to this guide but brush bar removal etc is quite different.
Unclip bin from body
Remove bin from body
Unscrew three soleplate retainers
Remove soleplate
Pull belt of motor shaft.
Pull brushbar out
The small hose here needs to be pulled off
It comes of quite easily
Now unclip the soleplate away from the foot of the vacuum
Both sides. It does sometimes require a bit of effort
Unclip this inspection tube
Now unclip these green plastic retainers, a screwdriver helps
Both sides
Just ease them off
Now put the vacuum in this position
Bend these lugs away from the body on both side
A steady hand is needed
And it comes off completely
This is what you should have now
Eight T15 torx screws to remove. Heres the first circled
Two on this side circled
Three at the bottom
The other two are behind the filter. Unclip the cover
Pull out this filter
The top two need unscrewing
Close up
With the screws out the motor outer case will pull apart
Remove from the body of the vacuum
Pull this piece of trim off
Four lugs on the motor case hold the lid in place
Unclip the lugs gently and remove the lid
The motor now needs pushing out of the case, this can require some effort and is best pushed with two thumbs (camera was in other hand)
The motor is now out of its case
This is the old motor and the top motor mount.
Note the wires and disconnet the motor
This is the new motor
I have taken the old motor mount and put it on the new motor
Now remove the lower motor mount from the old motor
And fit it to the new motor
Attach the wires and push the new motor back into the case.
There are 2 pins that push into the top mount (arrowed)
Put the lid back on
Refit this piece of trim
Sit it back into the body
Refit the top motor case and screw it together
Refit the base of the vacuum
Now refit the retainers on both sides
Refit the small hose
Clip the soleplate back
Push belt and brushbar back into position
Refit the belt
Check brushroll moves free
Refit soleplate and screw retainers
Refit the inspection tube
Replace the lid and filter
Refit the dust bin and test
