This service manual is intended as a supplement to the W600 series Service Manual.
Example of WM55A/ 66A Panel
General
Mechanically the machine is based on the WM55 (W640/W650) and WM66 (W660) respectively, except
for the panel and control unit. For more information see the service manual for the W600 series.
The difference in operation between the WM55/WM66 and WM55A/WM66A is that the new machines
are provided with a new menu logic, new preset programs, new program types and different options. The
machines also include a shop program for indication on a display intended for dealers.
