I have three machines all Janome, and never take them in yearly for service. Keep them clean myself, and they work fine. However my 10001 is in the shop now, I have had it 5 years and soemthig happened with the emb module so it needed fixing. Unfortunately the bill will probably be upwards of $159. And as others have said I put oil in the bobbing case (one drop) every once in a while and my dealer also said to put a drop in the bobbin winder on top. .
