Rotational direction of the mixer motor
Checking the rotational direction of the mixer motor
After being switched on, the appliance implements a
self-test. During this, the mixer is opened and closed
again.
Observe the rotational direction of the mixer motor dur-
ing its self-test.
Then manually set the mixer to "OPEN".
Note
The flow temperature must now rise. If the temperature
drops, either the motor is turning in the wrong direction
or the mixer insert is incorrectly fitted.
