Looks like the motor brushes on my Bosch washing machine may be on the way out so have been looking round for a new set. What concerns me is the huge difference in price between the manufacturers replacements and cheaper equivalents, approx £37 vs £7. After a recent false economy purchase of some fridge hinges, I am quite prepared to fork out for the proper part. However, I am intrigued by this big price difference. Has anyone had a similar experience?
