Danger!
Before replacing the component, comply with
the safety instructions in Section 11.1.
• Comply with the assembly and installation manuals
provided with the spare parts.
Replacing display or electronics
If you are replacing only one of the two components,
the parameter adjustment functions automatically. On
turning on the appliance, the new component takes over
the previously set parameters from the components
that are not replaced.
Replacing display and electronics
When replacing both components, after being turned on,
the appliance goes to fault and displays the error mes-
sage “F70”.
• In the second diagnostic level, under the diagnostic
number “d.93” enter the number of appliance variant
according to Table 11.1 (see section 10.1.2).
