The diagnostics defined are listed below:
1. Door open: If DIP1=0 (Not top loading), Ip=0 (door open) and programme running (start or in middle): This
is indicated by a one-impulse train.
2. Filling error: If PT=1 (Tank not full) for 10 minutes, and V=1 (filling): This is indicated by a two-impulse train.
3. Drainage error: If PT=0 (Tank full) for 3 minutes, and BD=1 (draining): This is indicated by a three-impulse
train.
4. Boiler heating error. If PT=0 (Tank full) and TC=1 (boiler temperature not reached) for 35 minutes. This is
indicated by a four-impulse train. The error is reset when the machine is switched off.
5. Tank heating error: If Dip4=0: If TT=0 (tank temperature not reached) for 90 minutes and MBL=V=0 (Wash
pump motor stopped and without entering water): This is indicated by a five-impulse train. The error is
reset when the machine is switched off.
9.5. OPERATION OF THE CONCEPT PLUS
The wash cycle of the machine includes a wash, drainage and a final rinse.
The tank thermostat maintains the wash water temperature and a motor pump sends this water with detergent to
the washing arms. The jets of water reach the dishes from different directions in order to guarantee a uniform
wash.
Between the wash cycle and the rinse cycle there is a pause of a few seconds to allow the detergent to drain off the
dishes into the wash tub. If the machine has a drainage pump, part of the water is drained from the tank and
replaced by clean rinsing water.
Lastly, the dishes are rinsed with mains water heated to between 80 ºC - 85 ºC / 176 ºF - 185
⁰
F to remove the
detergent from the dishes and at the same time regenerate the water in the wash tank, making it less dirty.
If the machine does NOT have a Cycle SELECTOR switch , just press the button corresponding to the required cycle
P1 , P2 , P3 , insert the basket with the dishes in the machine and close the door. The Led L1 , L2 or L3 corresponding
to the selected cycle flashes while the cycle is running. For the CONTINUOUS WASH cycle, press and hold P3 for
more than 3 seconds with the door closed; to stop the continuous wash cycle, press and hold P3 again for more
than 3 seconds with the door closed.
The cycle selected will remain selected until the selection is changed or the appliance is switched off.
