I havent got any pics of the inside's of the machine unfortunatly but I can describe it to you the best I can from what Ive seen of it

Its roughly the same as a normal machine but the outer tub looks much bigger than normal which makes it look strange LOL, the PCB is mounted on the right side of the machine, I think! but its hard to tell as the components and most of the cabinet have a fair bit of sound insulation padding around them which I was suprised to see!
Yeah the wrong motor theory I have is that they've put a motor in it think that it is strong enough to turn the bigger drum, which it is and it didnt have any problems at the beggining but after some use it shows that they wear out too quick because of the strain it is put under, the service engineer who had a look at mine has put new motors on 6 of my model of machine so far which proves my theory to a point I think
The Candy machine in the vid is how mine has gone, only it dosnt struggle quite as much, however its a lot louder with the weird ticking sound the motor makes now! LOL
I forgot to mention that in my last most that the engineer mentioned the new motor will still be a brush motor, but an AC or DC motor, cant remember which one it is, but the version which dosnt make so much noise, so it should be quieter, I was hoping that they could install an Induction motor onto it but apprently that requires a power transformer as they dont run on 240 volts and that cant be installed on my model. So hopefully the new motor and door seal will be the end of my troubles!
As im writing this it is on now, on a Non fast 30c wash with sensitive care added. Whilst I still have this motor I've had to use the sensitive care button as it reduces the agitation in the wash because, on a normal cottons cycle after its done its load sensing stage of the wash, which lasts about 10mins or so depending on load size, it starts heating and does roughly 14second tumbles and pauses just enough time for the drum to stop swinging and this for the motor in it now is too much and cannot cope with doing that for the entire cotton wash, therefore it overheats LOL!
P.S, I'll try and get a pic of the current motor in it once its been taken out by the engineer
Hope this helps!
