E20 HACCP Only - B11 Core
Temperature Probe Single
Point Fault
Error E20 is not shown in display.
Instead a probe sign with “?” is
shown as popup window. In case
the customer cooks in time mode
during fi rst step and during second
step switches to probe mode but has
no probe in place, the error E20 will
be shown in the error code list and
HACCP list.
