This chapter describes a mahcine with the wash program P03CH. The

machine has an electromechanical programmer, hot and cold water

connection, without heating and wash programs for laundrettes, coin-ops

etc.

To facilitate fault-tracing in the machine electronics, the circuit diagram is

divided into funcitonal sequences. The following sequences are described

in this chapter:

• Power supply and start, machines without coin meter ......... 2

• Power supply and start, machines with coin meter .............. 4

• Safety lock............................................................................ 6

• Rapid advance and program selection................................. 8

• Motor control ...................................................................... 10
