Before heating it should take water till first level frequency then
start heating.
Heater will be on max. 8 minutes after this 8 minutes if the temp.

(E05).
Or if the NTC connection is broken then it should give again E05
NTC failure.
At the end of heating, “SAU” visualization should make slow
blink to indicate that the step is over.
Note: If user changes the selector position, machine will do what
is defined for the new selected position.

At the end of pump activation, “SAU” visualization should make
