HOW TO VERIFY THE SIGNAL OF THE
FLOWMETER
To measure the signal it is necessary to
access to the control unit located on the
right side.
Remove the right side panel as shown in
Chapter 3.
With a tester measure the voltage al-
ternating between the ends of the faulty
flowmeter (see figure). Place the tester
caps at the terminals of the doser using
the references in the image.
The signal generated by the fan is a
square wave of about 5V.
If the dispenser is damaged we cannot
read anything.
7.6.1 REMOVAL OF THE FLOWMETER
To remove the flowmeter, proceed as it fol-
lows:
Remove the cup holder surface, the side
panels, the drip tray and the lower front
panel as described in Chapter 3.
Utilizing a Philips screwdriver, unscrew
and remove the head from the flowme-
ter.
