The Pasquini Livia G4 espresso machine replaces the discontinued Pasquini Livia 90 semi-automatic that was produced for over 15 years. The G4 brings a refreshing, new stylistic fortitude to the United States' home enthusiast.
There are improved features over the Livia90. Most importantly, the brain unit is located on the floor of the unit where there is the least amount of detrimental heat that could affect the motherboard. This feature alone will save a lot of replacements of motherboard.
Second, the grouphead is actively heated by a separate heating element as opposed to the passive heating (through metal) of the grouphead on the Livia90. The steam wand is cool to the touch.
Fully-automatic controls (1-cup, 2-cup) and also a semi-automatic dosing button ("P").
Stylistic stainless steel body panels with Pasquini logo.
Heat exchanger allows continuous espresso extractions (until the reservoir sensor cuts off power).
Automatic water-refill of internal boiler allows and continuous steaming (until the reservoir sensor cuts off power).
Water reservoir safety switch will turn the machine "OFF" when the water level is low in the reservoir.
PID temperature control sensor monitors the boiler temperature.
Nickel plated boiler secured to black frame supports unit during transportation.
Resettable safety thermostat under boiler to prevent overheating.
Adjustable overpressure valve for pump pressure.
Removable access panel on the bottom to reset safety thermostat and test/replace heating element.
41 watt vibration pump with brass output produces the 9 bar pump pressure required to extract espresso - remember, only 9 bar is needed for espresso!
Protected on/off switch.
Gauge for pump pressure.
Multi-directional steam and hot water wands offer ease of use with joystick controls.
Steam valve has a locking position in the upwards position.
Steam wand has internal insulation to keep it cool to the touch.
Particle filter on water intake hose protects pump from larger particles.
Thermostat controlled heated grouphead - a separate heating element and thermostat control the temperature of the grouphead for that perfect espresso.
Two cup warmers, one on the top and one on the front.
Accessories: double spout portafilter, single cup filter basket, double cup filter basket, blind filter basket for backflushing, plastic tamper, plastic scoop, grouphead brush, one pack of descaler, two Pasquini logo stickers.
Measurements:14.76" H x 9.84" W x 17.72" D (37.5 cm H x 25 cm W x 45 cm D).
Max cup height clearance: 3.75" (9.53 cm).
Weight: 41.89 pounds (19 kilograms).
Power: 1400 watts, 110 volts, 60 hertz.
Water tank capacity: 0.79 gallons (3 liters).
Boiler capacity: 0.4 gallons (1.5 liters).
Please use softened water - this means no magnesium and no calcium in the water. This is different than filter water which typically only removes sediment, bad taste and bad odor. Some filters do have limescale inhibitors which is better than a filter without.
Distilled water or reverse osmosis water can cause overfilling/leakage or not allow the machine to heat/operate normally.
Upon initial startup, it may take 90 seconds for the machine to fill in the internal boiler. While filling, please check to see that water level in reservoir is dropping. If it takes longer than 120 seconds, please stop the machine and call the service center as the pump may have an air pocket which needs to be cleared when the machine is cold.
Many customers tend to read the pump pressure gauge when the machine is sitting idle. The only time the pump pressure gauge has relevance is when extracting. If it is under 8 bar, the coffee grind may be too coarse or there is not enough coffee in the basket. If the pump pressure gauge goes over 9 bar, then the coffee grind may be too fine.
The PID shows the programmed desired temperature of the boiler water. Manufacturers have to make one of two decisions on the PID display when extracting espresso.
Show only the programmed temperature all the time, or
show the actual temperature reading.
Most manufacturers choose 'b' so the customer knows the actual water temp during the extraction. This does lead customers to believe that the temperature should be spot on always. In fact, it is the contrary. As cold water enters the system when the pump is engaged, the temperature will be reduced faster than the heating element can recover the programmed temperature. This is normal as much as with a heat exchanger machine with a boiler pressure gauge whereby the needle will go down a little while extracting. The range will change over time based on temperature of incoming water, ambient temperature, and a few other variables.
This machine does have a heater in the grouphead so the water is reheated there before it extracts the ground coffee.
