6.3 Error conditions
Figure 6.6 shows an example of an error condition. If the appliance enters this
condition, the display will show the following information:
• line one: error code comprising a letter and two digits, followed by the error
description;
• lines two through four: alternately, a brief explanation of the error, and a brief
action to resolve the error.
cNote
The displayed action to resolve the error may only be performed by a
service- and maintenance engineer.
There are various types of errors:
• LOCK OUT ERRORS
When the cause is no longer present, these errors require a reset with the
R button, before the appliance can resume running.
• BLOCKING ERRORS
These errors disappear automatically once the cause of the error has been
removed, after which the appliance resumes by itself.
The display does not show what type of error has been detected. For a detailed
overview of error conditions, please refer to chapter ’10 Troubleshooting’.
If, as end-user, you find the appliance in an error condition, you may attempt to
re-start the appliance by pressing the R button once.
However, should the error return or become persistent, you should contact your
service and maintenance engineer.
