Ascaso Steel Duo PID Dual Thermoblock Espresso Machine


The Ascaso Steel Duo PID has finds the balance between bringing a professionally dynamic designed espresso machine to a domestic setting.  There is no wait time between coffee & steam as steam is always readily available. With the addition of the PID, control of the temperature of your coffee and hot water is at your fingertips! New design features like the blue LED’s along the toggle switches, the portafilter handle is crafted out of Pyrenean boxwood, and an active cup warmer sets this machine a part from many home models in it’s price range.

PID Display
  • Adjustable temperature in one-degree increments.
  • Stand-by option available.
  • Coffee dose timer.
  • Programmable pre-infusion. (0 to 5 seconds).
  • Alarms (5): Water/coffee ratio, coffee or steam gauge, coffee group or steam. (Display indicates error type).
Control of Coffee Dose

Ascaso includes the ability to choose between single and double shot dosing for coffee, and upgrade from previous versions of the Steel DUO.

Active Cup Warmer

Unlike the other Steel DUO models, the PID version has a 38W plate under the top panel actively warms cups, versus warming the cups with passive heat.

Wooden Portafilter Handle

Ascaso has crafted the portafilter handle out of Pyrenean boxwood–adding artful, chemical-free durability that you can feel!

Stainless Steel Body

Manufactured in stainless steel for maximum sturdiness, coated with a black or white enamel.

Thermoblock Technology

The thermoblock is designed of aluminum for fast warm up times and thickness for good temperature stability. Aluminum also avoids ‘pitting’ in cases where purified water is used. The inside pipe for which water comes in contact for heating is made of stainless steel. Another bonus? The thermoblock in this case is less prone to limescale build up from magnesium and calcium – limescale is a major factor in causing problems on espresso machines.

3-way solenoid valve

Allows you the ability to remove the portafilter immediately after brewing, turning your grinds into a puck, rather than a watery mess!

Quality brewing group

Made of chrome plated brass, the grouphead on the Ascaso Steel DUO evenly distributes heat and reduces hotspots for more temperature consistent espresso. It has also been designed to evenly distribute water across the coffee grounds for a better extraction.

Adjustable Over Pressure Valve

The ability to adjust the over pressure valve allows you to perfect your coffee to the flavor profile that is distinctly yours. The possibilities are endless!

1.3 L Water Reservoir

A microprocessor pulsates the pump so water in the reservoir continuously fills the thermoblock for continuous steam – until the reservoir runs near empty.

Illuminated Brew Area

Making coffee early in the morning, or who knows, late at night has never been easier! Ascaso has designed the Steel DUO with an illuminated work area so you can guarantee your coffee is making its way to your cup–no matter how dark it is.

Versatility between different brewing methods

No conversion kits needed here! As of April 2014, Ascaso has combined the ground / pod system into one. Simply switch out the filter basket to brew with freshly ground coffee or E.S.E pods. Ascaso provides FOUR different baskets.

Accessories included
  • Dual-spout portafilter.
  • Single and double pressurized filter baskets, Double non-pressurized basket, E.S.E Pod basket.
  • Aluminum tamper–an upgrade to the plastic tamper most manufacturers include.
  • Plastic scoop for pre-ground coffee.

Espresso Machine Warning:

  • ELECTRICAL WARNING: To avoid electrical damage to this espresso machine which is not considered a manufacturer's defect, please acquire and install a single-outlet surge suppressor rated at 1080 joules or higher. the lack of the recommended surge suppressor, the espresso machine can be damaged at the power switch, the electronics, the heating element, the pressurstat or the wiring inside.
  • WATER WARNING: To increase the useful life of and not damage your espresso machine, please use softened water. Softened water is water without calcium and without magnesium, but still has other minerals for espresso extraction. Do not use distilled water, purified water, nor reverse osmosis water as these types of water create oxidation with the metals and cause the same damaging effects as limescale.
  • DESCALING WARNING: We do not recommend descaling unless there is an issue with the espresso machine. The reason is that too much descaling can eat away at the metals and gaskets inside an espresso machine.

      A The top of the machine is higher at the front, it slopes to the rear. Assuming you could remove the cup rail (I don't know about that) at the front it is precisely 14", and at the rear, 13". Again, these measurements are from counter to top of the unit, absent of the cup rail. With the rail, as shipped, 13 5/8" at the rear and 14 3/4" at the front, again factor in it is sloped. These are exacting measurements,so if anything, make sure you have at least this much room. Love the machine.

      To set the pressure, the blind basket needs to be inserted into the portafilter, and then the portafilter inserted tightly into the grouphead.

      Power on the machine. Press the coffee switch, and the pressure should increase on the brew pressure gauge.

      There is a screw on the underside to the left of the grouphead. Turn this screw to increase or decrease the over pressure release valve. Do this within 30 seconds of operating the pump.

      The over pressure valve only manages the maximum pump pressure by releasing the excess pump pressure.

      Yes, the OPV opens and sends water back to the reservoir or drip tray depending on the version you have.

      Please check the steam tip to make sure it is not clogged. Otherwise, considering its age, it should be checked by a professional - possible local to you or 1st-line.

      Sorry, at the time of this writing, we currently do not sell Cafelat gaskets. Hence, we are unable to provide an accurate recommendation other than to purchase the OEM gaskets we sell per the diagrams in the support section tab at the top of our web site.
