1. Introduction
In your hand you are holding ASKO’s Service Manual for the new generation of dishwashers.
The dishwashers in the DW20 range are available in four different basic models with the type designations
DW20.1, DW20.2, DW20.3, DW20.4, DW20.5 and DW20.C. Presented on the following page are the
different panels available for each type, which lets you readily identify the machine type. The different
variants have different designations from market to market. The type designation is most important when
you need to identify a particular type of machine.
You can find this on the machine rating plate positioned on the right-hand side of the inner part of the door.
It must be easy to carry out servicing on dishwashers. It is important for you, as a service technician, to
benefit from the conditions necessary to enable you to work in an effective and satisfactory fashion. We
hope that this Service Manual will be a useful tool in your daily work.
