5.3. ROD AND SAT TESTING CYCLE:

START OF A LONG TESTING CYCLE

Drain V + 0 sec.

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.

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.

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.

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.

WASH MOTOR activation.

TURBINE-filling of 2 litres, in dynamic phase (total 4 lt), (wash motor on).

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
