my neighbor does her own and has for decades. Her daughter has a machine exactly like my 2662. Got it from the same place as I did. Daughter was having some trouble with hers and since it was under warranty, she took it to them for repair. They only serviced the older machines. Had to be sent to the manufacturer by the owner. Her mother "had at it' and runs smooth. DAughter never cleaned after using it. The only type of problem I ever have with it is due to "user" error.
