-

Explosive ignition.

The manual includes a table with general errors (13.2 "Troubleshooting table for general errors").

•Displayed errors

Errors are reported on the display, as follows:

-Line one: an error code and a brief description. The code consists of a letter and two digits.

-Lines two, three and four: a long description, alternating with a recommended action. See the figures. The first shows a possible error, the second shows the appropriate checking action.

There are various types of errors, all falling into one of two groups:

-LOCK OUT ERRORS

When the cause has been removed, these errors require a reset with

the button, before the appliance can resume operation.

-BLOCKING ERRORS

These errors disappear automatically once the cause of the error has been removed, after which the appliance resumes operation by itself.

The manual includes a table of error messages that can appear on the (13.3 "Troubleshooting table for displayed errors").
