6.1. ERROR HANDLING
The timer allows the full control of the washing machine. When an error occurs then automatically the machine
will go over to a safe state. With the diagnostic program you can determine the problem (See „Programming
manual"). This program will test all the functions of the washing machine.
If a failure occurs then the computer will display a diagnostic message. The message is a number that correspond
with a typical problem.
If a failure occurs and the timer gives no message you can consult chapter 6.2.
