Ascaso Steel Uno Professional PID Version 4 Espresso Machine


  • Ascaso Steel Uno Professional PID Version 4 Espresso Machine



    Coffee aficionados are in for a treat with the Ascaso Steel Uno Professional Espresso Machine. It is now built with a PID display that provides functionality to fine tune the boiler temperature. This enables the calibration of the water temperature based on the type of coffee. Some blends entail a mid-level temperature of 195°C, while others strike the point of 204°F. Espresso drinkers are set to find the elusive taste to complement their discerning palates.

    Ascaso has merged the ground and pod system since the machine’s April 2015 production. It features a newly designed grouphead made with completely solid brass, and no longer necessitates conversion kits. Internally, no changes were made from the third edition.

    Version 4 Changes:

     As of April 2015 production, Ascaso is combining the ground/pod system into one. This means no more conversion kits. A new grouphead design, now made with 100% solid brass. There are no internal changes from Version 3.

    This extraordinary home-model espresso machine has incorporated many improvements over its predecessor:
    • a) There is increased cup height between portafilter spout and drip tray to 3.35 inches
    • b) The lateral removable water reservoir allows easy access for refill and cleaning without moving moving machine away from overhead cabinets. It also allows you view the water level.
    • c) The featured cool touch and multi-directional steam wand allows brief handling for moving an internally piping, hot wand.
    • d) The rubber protector over wand allows holding the wand for longer periods of time (we do not know of any cool touch wand will allow you to hold the wand for more than 5 seconds continuously)
    • e) The steam wand is made of stainless steel, unlike chrome over brass found on other machines
    • f) The 325cL brass boiler is plated with nickel and incorporated with a professional grade 3-way solenoid valve
    • g) The professional-grade 58mm portafilter handle was designed and manufactured with a 10 degree tilt for ergonomic handling
    • h) The non-slip grip on portafilter handle offers a feel of professionalism in the home
    • i) A solid aluminum tamper is included with the accessory kit
    • j) Highly polished filter baskets with micro-fine smooth holes offer superior extractions over standard baskets.
    The main reason to get this machine is the taste of the espresso in the cup! The PID controller and thermal sensor on the boiler makes it happen at such an affordable price!
    • Warranty: 2-year parts and labor provided by My Espresso Shop
    • PID temperature programming allows user to change boiler temperature through the use of the digital display/control panel on the front panel of the machine. The display reads out the current temperature of the coffee boiler.
    • Brushed stainless steel finished body over a black enamel painted steel frame.
    • Water reservoir removable from the right SIDE of the machine
    • Nickel-plated brass boiler capacity: ~325cc.
    • Brass boiler is located directly over the brass grouphead for superior temperature stability compared to boilers that are offset from the grouphead.
    • Ergonomic-styled brass filter handle with plastic grip.
    • Slide out drip tray made of plastic for easy cleaning (please note drip tray cover is part of machine). Front portion of pull out drip tray is in brushed stainless steel.
    • Four selection switches: power on/off, espresso extracting, hot water, and coffee/steam mode.
    • Vent in top rear of machine allow heat near water reservoir to escape.
    • Blue lights (left to right) indicate power, heating (on when heating in coffee or steam mode), pump for hot water on, and steam mode (on when machine is in steam mode).
    • Three-way solenoid valve allows the immediate removal of the filter handle when the espresso extraction is completed. The three way valve also allows the user to backflush the grouphead.
    • Multi-directional steam wand allows the desired angle of the steam wand into the steaming pitcher (recommended size 20 oz or less) on counter or placement over drip tray.
    • Passive cup warmer on top with side guard rails.

      1. The instructional manuals for Ascaso are printed for worldwide distribution and covers almost every model produced worldwide. With this in mind, there may be features, accessories, or colors available in Ascaso equipment in other countries, but not available in our models produced for the United States.
      2. To program the boiler temperature, the user needs to press the left little button on the temperature display and then immediately press the right button to show the program temperature. The left button can be pressed for each degree to decrease, and the right button can be pressed once for each degree to be increased.
      3. The right button on the temperature display can be pressed and held to shut off the PID controller
      4. The PID controller will stay on even when the main power switch is shut off
      5. When turned off, the PID controller will remain to display OFF until the machine is unplugged
      6. If the unit arrives with a temperature display in Celsius, it can be changed. Before plugging the electrical cord to the electrical outlet, both buttons on the temperature display need to be depressed and held while and other person plugs the electrical cord into the electrical outlet. Once F.03 is displayed, the two buttons can be released. Depress and release the right button once. It will display Celsius. Immediately depress the right button and F will display. Leave alone for 20 seconds, unplug the electrical cord from the electrical outlet, and then plug it back in after waiting 10 seconds. The display will not be in Fahrenheit.
      7. This is different from Version 2 in that the PID is now internally connected to the boiler. In previous versions it was connected to the outside of the boiler.
