The new V3 has just arrived and everyone is asking what is the difference, so we got onto the wonderful people at Lelit and they have provided us with the following document detailing the exact upgrades.
Coffee boiler temperature
Steam boiler temperature
Default temperature scale
Programmable pre-infusion times
Programmable low flow times
The brew temperature off-set
Hot water and steam taps with LELIT logo embossed and visible from above. They are longer than the former ones, therefore the wands will not touch the body of the machine, preventing any possible scratch. This element was already present in LELIT Bianca V2.
IMS filters made of AISI 304 stainless steel: 1 dose (9-11 g), 2 doses (16-18 g), 2 doses PLUS (18-21 g), blind. This element was already present in LELIT Bianca V2.
Water tank with LELIT logo embossed. This element was already present in LELIT Bianca V2.
We have updated the software operating the machine. This has allowed us to introduce the new Low flow function, the stand-by mode and the warm-up optimization.
LCC – LELIT Control Center
LCC is the brain of the LELIT machines. In Bianca – PL162T V3, new functions have been included. Now, the LCC lets you manage a bigger number of settings in your machine:
The temperature of the coffee dispensed.
The temperature of the steam dispensed.
Steam boiler enabling/disabling.
Selection of the temperature unit measure.
Programmable pre-infusion times.
Programmable low flow times.
Sleepy mode enabling/disabling.
Partial and total doses counter.
Chronometer of the coffee dispensing.
After 30 minutes of inactivity, the machine will go automatically in stand-by mode.
The ON/OFF light blinks.
Low flow START
Low flow start, which refers to the time slot from 0 till what the user sets.
Low flow FINAL
Low flow final, which refers to the time slot from what the user sets till the end of coffee brewing.
Brew temp off set
This value either increasesor decre- ases the coffee boiler temperature during coffee brewing, changing the temperature of the water coming out of the grouphead.
LOW FLOW OVERVIEW
We would like to underline the most significant improvement of the machine: the LOW FLOW. In Bianca V3 we automatised the paddle movements which has two main advantages for LELIT users:
The machine can be easily operated also by less expert users, as they do not have to pay particular attention to the coffee brewing.
For the more expert users, this upgrade means that the pressure and flow profile can be precisely repeated multiple times. This does not mean that the paddle becomes useless, but it can be used in addition to the setting of Low flow.
LELIT Bianca V3 can perform four scenarios:
Full flow or standard brewing Low flow
Full flow with preinfusion Low flow with preinfusion
In Bianca V3 we have 4 different mode of use:
Always ON: when the user deactivates stand-by and sleep mode. This means that the machine is always ON.
Sleep mode: after a set time (from 30 to 540 min), the software brings the coffee boiler down to 70°C, while steam boiler goes down to 0°C.
E-Mode: steam boiler is always OFF
Stand-by: this is the novelty of Bianca V3. After 30 min, steam and coffee boiler and LCC are turned OFF. This is the factory setting according to the European norms.
WARM UP OPTIMIZATION
The newly designed NTC system is able to minimize the time for the machine to be ready.
BREWING TEMPERATURE OFFSET
This value is a sort of fourth value of the PID. It was introduced to correct the foreseen thermal error during brewing. When brewing a cup of coffee, the machine dispense water hence cold water is introduced in the hydraulic circuit and the boiler. Cold water messes up with the thermic of the machine. This is when the brew temperature offset is needed. In fact, during brewing, the software changes the set point by increasing or decreasing the temperature of the chosen offset – range values ± 25°C. In this way the user has an additional value he can use to personalise his brewing profile.
Note. Please note that leaving the machine always ON might wear out the components faster.
Water tank cover
Manometer for coffee pressure
LCC (LELIT Control Center)
Multidirectional, anti-burn steam wand
Wide cup warmer
Paddle to adjust the coffee water flow
Hot water knob
Hot water wand
Coffee distribution group
Coffee dispensing lever
Double manometer for pump/steam pressure
Removable water drainage tray
Filters and filterholder cleaning
It’s necessary to clean the filterholder to eliminate the coffee oils that affect the taste of your drinks negatively.
Place a jug under the hot water wand (11), turn the knob anti-clockwise and take out about 1 l of water.
Insert the filterholder and the used filters into the jug but pay attention not to immerse the filterholder handle.
Add 2 bags of detergent powder.
After 15 minutes, empty the jug and rinse the filterholder and the filters with plenty of tap water.
How to Backflush your Bianca
Insert the blind filter into the filterholder and pour 1 bag of detergent powder into the filter. Insert the filterholder in the group head (12) and lift the group lever (13) for 10 seconds.
Stop the function by lowering the lever (13) completely and wait for 10 seconds. Repeat the procedure 10 times.
Remove the filterholder from the group head (12) and rinse it with hot water from the brewing group.
Re-insert the filterholder in the group (12) and repeat the previous operation 5 times for 10 seconds each time, without detergent powder.
Remove the filterholder and take out the blind filter.
Empty the drip tray (15) and rinse the filterholder, the filter and the drip tray with plenty of tap water.
How to clean your Steam wand
Fill a jug with 500 ml of cold water, add the content of 1 bottle of detergent liquid and immerse the steam wand (6) in this solution.
Open the knob (2) by turning it anti-clockwise and dispense steam for 5 seconds.
Stop the function and wait for 5 seconds.
Repeat the operation 10 times.
Repeat the entire procedure using 1 l of fresh water to rinse the steam wand properly.
