7) Check that the drain trap does not show water leaks
and is firmly secured to both the machine and the
drain.
8) Check if the pumps correctly suck washing liquids.
To do this, check that the liquid rises along the tube
connected to them.
6.1.1 Loading the chemicals
When changing the tanks chemicals, it is required to
perform the manual filling of the hydraulic circuit. This
phase is important because it prevents any air bubbles
present in the pipes from causing an interruption of the
cycle following an incorrect reading of the flow meters.
To fill the pipes after changing or refilling the chemicals,
proceed as follows:
1) Open the door using the “DOOR” button on the
touch screen (4 Fig. 13), if the door is already open,
leave it opened;
2) Remove the rack if inserted, in order to have full
visibility of the washing chamber;
3) Press and hold the button corresponding to the
dosing pump you wish to activate to manually load
the hydraulic system: key P1 (1 Fig. 13) on the touch
screen for pump DOS1; key P2 (2 Fig. 13) on the
touch screen for pump DOS2; key P3 (3 Fig. 13) on
the touch screen for pump DOS3; key P+ (4 Fig. 13)
on the touch screen for pump DOS4.
4) Wait a few seconds to see in the lower right part,
the area where the chemical inlet holes are present,
a constant flow free from air bubbles.
5) Release the button and repeat the sequence from
3 to 4 for the other dosing pumps that need to
recharge the hydraulic circuit.

CAUTION! This phase must be performed
at the first installation of the machine, in
this case, let the liquid flow for a few more
seconds to ensure the correct and full
loading of the hydraulic system.
