5.3. ROD AND SAT TESTING CYCLE:
1.
START OF A LONG TESTING CYCLE
2.
Drain V + 0 sec.
3.
Reading of turbidity sensor and pressure switch in empty state.
3.1. If it read a max turbidity value (clean, connected), it turns on the
Rinse Aid
led up to the end of
the cycle.
3.2. If it read a min turbidity value (unclean, disconnected), it turns off the
Rinse Aid
led up to the end
of the cycle.
-
If Rinse Aid led remains off, the turbidity sensor does not work or it is disconnected. Probable
defects: faulty or disconnected turbidity sensor, dirty optical tube, faulty/disconnected Rinse Aid
led.
4.
Salt led switches on simultaneously to Rinse Aid led (up to the end of the cycle)
-
If the Salt led remains off, it does not work
Probable defect: disconnected Salt led, faulty connection.
5.
TURBINE
-filling of
2 litres
, in static phase + (searching of alternated wash position, washing up + down).
-
if the Timer does not receive any signal from the turbine, but water is filling the tank, once reached
F static (1,2litri), it activates the wash motor and fills up to reach the F dynamic pressure switch,
for a max time of 153 sec. from the activation of the solenoid valve.
Probable defect: faulty or disconnected turbine.
6.
Pause of 10 seconds, checking of HIGH PRESSURE sensor, (it must be off, stand-by position).
-
If H.P. sensor is on, the dw is in filter cleaning alarm.
Probable defect: faulty or disconnected H.P.
7.
WASH MOTOR activation.
8.
TURBINE-filling of
2 litres
, in dynamic phase (total 4 lt), (wash motor on).
9.
I Checking pressure switch state (V - P), (wash motor on)
9.1. If it is in F (full), filling phase is finished, the dw only washes
9.2. If it is in E (empty), it fills and wash up to reach F pressure switch or a max quantity equal to 8 lt,
-
If at 8 lt the pressure switch has not still reached F state, the dw is in filter cleaning alarm.
Probable defect: faulty pressure switch, cables disconnected/inverted.
10.
WASH MOTOR on, 1 minute of preparation to filling.
-
In case it fills a quantity higher than 8 litres, the dw is in filter cleaning
Probable defect: faulty pressure switch, cables disconnected/inverted.
11.
Activation of WASH MOTOR, HEATER, ELECTRO-DISPENSER, (washing up/down) 20".
12.
Checking of HIGH PRESSURE sensor 5sec. (it must be on).
-
If high pressure sensor is off, the dw is in filter cleaning alarm.
Probable defect: faulty HP sensor - DECANTER spout clogged.
13.
WASH + HEATING 1 minute
14.
If the dw has selected Half Load, see point 15.
-
If the dw has selected the alternated wash, see point 16
15. Section about the control of dw with Half Load (no alternated wash)
15.1 Deactivation of wash pump
