When a malfunction is detected in the components of the machine which prevents further processing,
a fatal error is issued. Every fatal error message begins with an error code of the form “EXXX” where
the XXX is a one to three digit number. For example:
“E18 Pump Failure!”
The fatal errors can be classed into 10 families as listed in Table 14-3. If the error persists after
performing the actions listed in the Operator Response column, call the authorized technical support
service.
