My fancy pants washing machine has stopped working - it is helpfully about three months out of warranty 
Dr Google points me in the direction of the carbon brushes, I have watched a YouTube video and was convinced I could do that shit have it up and running in next to no time. However I didn't appear to be able to order the (cheap as chips) carbon brushes anywhere. So after an interminably long and painful conversation with a very pleasant lady in an Indian call centre (who gave every impression of never having seen a washing machine before) I have managed to locate the Mecca of washing machine parts.
On this call I was blithely told that the reason I was unable to find the brushes was because they don't actually do them as they are built in to the motor. So yes, I would need a whole new motor at a cost of £140. DH has meanwhile insisted A Man comes to inspect the infernal machine so by the time we've paid him, bought the part and then inevitably paid him to fit it we are likely to be over £200 down.
Obviously we will have to do it, but I truly don't think IABU to think this is daylight robbery
