Resins - Softener, Regeneration And Washing Phase; Drying Phase - Only For Gw4060, Gw4190 Series - Smeg GW2145 User Manual

4.6.1

RESINS - SOFTENER, REGENERATION AND WASHING PHASE

The softener incorporated in the device removes calcium compounds from the intake water to reduce its hardness.
The softener comprises a container of ion exchanger resins, which must be regenerated regularly.
The appliance decides when a resin regeneration and washing cycle is needed depending on the hardness set and the
quantity of water treated.
Resin regeneration and washing cycles are performed at the start of a washing cycle, to avoid the risk that standing
brine (salt and water) might cause corrosion.
4.6.2 DRYING PHASE – Only for GW4060, GW4190 series
The drying phase is included in the washing and thermal disinfection cycle, except in programs
"1 Prewash", "Auto-Disinfection" and "16 Service".
When a program which includes the drying phase is selected, the LED of the function illuminates.
ADJUSTING THE DRYING SETTINGS
The specific buttons for this function allow the effectiveness of the drying process to be regulated by increasing or
decreasing the total time of this phase. 3 dashes light up on the display if the default drying settings are active, while 2
dashes or 1 dash indicate gradually shorter times.
STANDARD STRUCTURE OF THE DRYING PHASE, 3 STEPS
Drying
total time:
t_d = t_1 + t_2 + t_3
Characteristics:

Duration, with 0 dashes
NOTES
The "target time" stated in the table refers to the time specified in the annexed "PROGRAM TABLE" document.
In a standard program, e.g. with drying having t_target=25min, the total time of the phase is calculated as follows:
t_d = t_1 + t_2 + t_3 = 10 + 25 + 4 = 39minutes.
If the final temperature is below 40°C during the last phase of the washing cycle, step 1 is completely omitted, since
there is no need to expel steam: t_1=0.
Target temperature: the temperature value in the program table, which refers to the temperature reached by the
monitoring probe TA in the drying duct. The temperature in the well during drying is about 30°C below the target
value. For example, for a drying program with T_target=110°C,
SEPARATE DRYING PHASE
Users can also select a SEPARATE DRYING CYCLE by pressing the "Drying Decrease" button for 2 seconds: the
message "PdrY" appears on the display.
The drying time can still be adjusted as described above.

Step 1
[t_1]
The fan speed is reduced
(1/4 - 1/2 of full speed) to
aid the controlled venting
of steam from the well.
t_1 = 10 minutes
t_1 = 10 minutes
t_1 = 10 minutes
t_1 = 4 minutes
T_well ≈ T_target - 30°C = 110°C – 30°C = 80°C.
GW2145 - GW1160 - GW4060 - GW4190
Step 2
[t_2]
Time and temperature
equal to target values set
by the program. Fan at full
speed.
t_2 = target_time
t_2 = 0.5 x target_time
t_2 = 0
t_2 = 0
Step 3
[t_3]
Cooling phase for load and
heating elements.
t_3 = 4 minutes
t_3 = 4 minutes
t_3 = 4 minutes
t_3 = 4 minutes
