Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries
OK are you happy to work on the motor?
OK firstly take the motor off and check the motor brushes and come back to me with what you find ~ Ian
OK would you now rate the service given so far this allows me to shut down the question whilst allowing all future questions to be answered on a free of charge of basis. ~~ Ian
OK if you look at it from the opposite end to the belt pulley, if you go to the other end you will see two plastic L shaped things that are screwed to the motor body with a single wire coming off them, can you see these?
http://parts.indesit.co.uk/shop/spare-parts/washer-dryers/mechanics/genuine-motor-carbon-brushes/p/C00194594 ~~ looks like these
OK pull the wire off one of these bushes and then unscrew the brush assembly and take it off, when you are off come back to me.
typo ~ have it off #
OK if you look at where the carbon comes out of the holder, how long is it from where it exits the brass holder ?
ie how much have you got sticking out?
OK you need to replace them, you should have a minimum of 15mm more like 25mm of carbon showing, if you go to your local repair shop taking the one brush with you, match up a set and using the connected one as a pattern one by one replace them, put the motor back in and you should be good to go. Only thing is first couple of washes make them half load to bed in the brushes. Think you will be OK now just need to change these and you'll be good to go.
Would you now rate my service ~ if you need further info give me a ping ~ Ian
