8.4.1
Restricted operation
In case of a malfunction of the automatic hood system, the machine switches to re-
stricted operation. The dishwashing machine can still be used for rinsing, but the
hood must be opened and closed manually as far as it will go. The programme can
only be started via the wash key.
During restricted operation, message 161 is permanently displayed. The cause of
the fault (messages 19, 20, 157, 158 and 160) lies in contradictory or non-existent
signals concerning the upper and lower hood position.
Troubleshooting
Normally, it is sufficient to perform a complete hood drive (open/closed/open) at
moderate speed for calibration. If successful, a message 162 to be acknowledged
may appear, and if the software is newer, a message 163 not to be acknowledged.
The machine then resumes normal operation.
It is also possible to disconnect the machine completely from the power supply (no
emptying is necessary). After initialisation, all functions are available again.
