32. WASH CYCLE
The machine cycle includes a wash, drainage and a final rinse, with an optional dryer.
The tank thermostat maintains the wash water temperature at between 55 - 65 ºC and motor pumps circulate this
water with detergent towards the wash arms. The jets of water reach the dishes from different directions in order
to guarantee a uniform wash.
The wash system starts when the wash actuator located in the rear internal part of the machine detects a basket,
and stops automatically when there are no baskets to be washed.
There is a drainage zone between the wash zone and the rinse zone which allows the detergent to drain off the
dishes towards the wash tub.
In the rinse zone, the baskets are rinsed with mains water heated to between 80 ºC - 85 ºC, mixed with rinse aid to
remove the detergent from the dishes, which at the same time regenerates the wash tank water, thus reducing the
level of dirt in the tank.
The rinse system starts when the rinse actuator located in the rear internal part of the machine detects a basket,
and stops automatically when there are no baskets to be washed.
An optional drying module is available for heating and expelling air at a temperature of 55 - 65 ºC so that the dishes
comes out completely dry. The dryer is automatically deactivated several minutes after the last basket has come
out.
If the water input temperature is lower than the specified temperature, the times
required to return to the operating temperatures will increase and productions rates
will be lower.
32.1. INTERRUMPING THE WASH PROCESS
The wash and rinse processes are deactivated after the baskets have passed through the machine and the feed
belt automatically stops after 10 minutes without detecting incoming baskets.
If, at any time, it is necessary to interrupt the wash process, the best way is to Press the START/STOP . The feed
belt stops and the wash and rinse processes are interrupted. If the button is pressed again within a short period of
time the machine will start to operate again. If not, only the feed belt starts again.
Other ways to stop the machine, but which are not recommended unless absolutely necessary, include the
following:
•
Selecting position 0 using the SELECT . This will switch off the machine. The wash process is not restarted.
Any basket that is in the appliance when the machine is stopped should be reinserted as the wash has
been interrupted and not completed correctly.
•
When the door is opened, ( CAUTION !) the feed belt stops and the wash and rinse processes are
interrupted, but hot water may splash and cause burns.
•
Press the emergency button ES to switch off the machine which will stop operating completely. ONLY USE
IN THE EVENT OF EMERGENCY.
32.2. DRAINAGE AND SWITCHING OFF THE MACHINE
At the end of the working day or when it is necessary to change the wash water because it is too dirty, the wash tank
should be drained.
To drain the machine, just remove the overflow. The machine should be switched off first.
To switch off the machine, select position 0 using the switch SELECT .
At the end of the work day, the machine should be emptied and the water disconnected using the water shut-off valve,
together with the electricity, using the magneto-thermal switch/setting the mains switch IG to OFF , and the machine
