SOFTWARE REQUIREMENTS
Heater
Heating relay must be switched with un-supplied
Heater. It means: - Stop Circulation Pump;
Wait (pressure switch certainly open);
-
-
-
-
Open/Close Heater Relay;
Wait (Heater relay certainly
close); Start Circulation Pump.
If Tablet is selected, heating steps must be < 58°C for steps before last rinse.
Water Fill
Action: Water Load is obtained by flow meter signals. When a fixed quantity of
water is loaded, the reaching water level is checked by the activation of circulation
pump. When the pressure is high enough, the pressure switch is activated. Precaution:
At the start program a drain 30” + empty is executed before fill.
When Inlet valve is ON, if there aren’t flow meter impulses, failure routine of “absence
of flow meter impulses routine” works (see on failure chapter).
If pressure sensing switch turn OFF during the wash, after a drain +20”, another water
load is executed (also see”return empty level” failure in failure chapter).
Water fill must work:
Pressure > 0,8l: all OK
0,3 < pressure < 0,8l: OK with time out
Pressure < 0,3l: stop cycle.
Note:
T2: lower spray arm starts.
16

Water drain
Precaution:
if pressure switch level doesn’t switch in Empty level (during circulation pump on),
failure of Water drain works (see failure chapter).
NOTE:drain is performed with lower spray arm.
Detergent dispenser step
T2: for the detergent step 2’ of upper spray arm are performed.
Rinse aid dispenser step
If the door is opened and re-closed during washing program, without a re-start program,
detergent dispenser must return in Rinse aid distribution state.
T2: for the rinse aid step 2’ of upper spray arm is performed.
FEATURE OF TIME PHASE:
At the beginning o the main wash of eco program, If temperature of water < 30C , Time
phase is not activated at the main wash of eco program
At the beginning o the main wash of eco program, If temperature of water > 30C , Time
phase is activated at the main wash of eco program
These two rules cover only eco programs.
Action: Water drain starts with drain pump ON for 33”. After 30”, circulation pump
ON.When empty level is recognised (by pressure switch signal), the circulation pump
stops and the machine continues for the request steps.
REGENERATION CYCLE
When it occurs the regeneration valve works after last rinse and during the drying steps.
When it occurs the regeneration valve works after last rinse and during the drying steps. There
are 6 hardness levels.
Water Hardness level Litres
Level 1 Never
Level 2 116 lt
Level 3 64 lt
Level 4 52 lt
Level 5 46 lt
Level 6 16 lt
The consumed litres are counted by flow meter impulses.
In case of flow meter broken, the litres corresponding at the flow meter time out are used
If user cancels a program during regeneration or after regeneration and before resin wash, at
the beginning of the next program the dishwasher performs the resin wash to remove the
salty water from the resin chamber. The resin wash will be: load 2 lt of water with drain pump
on. During the resin wash the circulation Pump must be off.
Regeneration is not performed at prewash program
If l water hardness level is changed from lower to higher, regeneration cycle is performed at
the end of the first program
If l water hardness level is changed from higher to lower, regeneration cycle is not performed
at the end of the first program. Regeneration is performed after water level reach to value of
level
17

•If Water hardnes level is 5 or 6
- First regeneration step is performed 0,2lt water
•If Water hardnes level is 2 or 3 or 4
- First regeneration step is performed 0,1lt water
•If Water hardnes level is 1
In case of Tablet option ON (only mod. T13 and T21):
- If the level set is less than L4: the regeneration cycle is not performed, but the quantity
of consumed water is counted. When the target value is reached, at the first cycle without the
tablet the regeneration cycle is performed.
- If the level set is equal or more than L5: the regeneration cycle is performed when the
quantity target is reached.
