Replaced brushes in this miele yesterday. Ran on 600 spin to bed in new brushes. Then ran on express wash and left. Cust rang later to say it completed express wash ok but when a new wash was selected it faulted with Mechanical fault E60. Only other thing I noticed was original brushes were very unevenly worn as in one was completely gone and sooted up on end, other was about 70{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}. Any advice on this one please or a service manual if available.Thank you.Paul.
