Alex Duetto IV Plus             

One-year factory parts warranty on defective parts Plus 1 extra year 


The Izzo Alex Duetto IV Plus, features dual boilers with independent temperature adjustment by the PID controller with built in shot timer. With a rotary pump and an E61 brew group, the Izzo Duetto espresso machine can be operated using either the portable water tank or connected plumbed to a water line.


Izzo unwavering focus on quality from the stainless steel frame, gorgeous industrial stainless steel body, down to the bits that you won’t see - like the stainless steel mushroom and giclée. The Alex Duetto not only stands out on the counter of your kitchen, but you’ll be just as impressed as we are daily with the build quality for decades to come.


Plenty of room - nearly six inches of cup clearance even your favorite mug will fit under the group! Not only is the Alex Duetto an impeccably made dual-boiler home espresso machine, but it has an incredibly flexible feature set as well.


Alex Duetto 4 has updated the motor mounts to reduce vibration while activated. The pump and motor are where a majority of your machine’s noise will stem from; in addition to the new motor mounts, an even quieter rotary pump has been installed. There is now also a solid-state relay (SSR) which is more reliable and quieter. The drip tray is equipped with two small magnets that reduce vibrations within the drip tray.


What is Pre-infusion? Pre-Infusion is the act of introducing water to your puck of coffee inside your insert basket at a lower pressure, usually 1-4 bars, prior to full pressure. On an E61 group, automatic pre-infusion using residual pressure, either within your brew boiler, or your water source’s line pressure. The benefit of pre-infusion is that it settles the coffee within your portafilter’s insert basket reducing channeling and improves extraction. 


Switching water sources is made incredibly simple with the single toggle switch located behind the magnetic drip tray. Easily switch water sources from the nearly three-liter reservoir to direct-plumb. The Alex Duetto also has the ability to easily switch between the most common configuration for the home kitchen, 15-amps, or ‘full-power’ mode with 20-amps. Quickly switch between the two with a couple of clicks of your built-in PID controller.

How do I choose between 15 or 20 amp on my home espresso machine? The main difference is how the espresso machine’s power is distributed between each of the boilers. There are many benefits to each power mode, but the main thing to consider between the two is what your home set-up near your new home espresso machine is going to be… 

 Each boiler of the Alex Duetto is independently controlled and operated. If you’re not using the service boiler, this is where your steam and hot water comes from, you can turn that boiler off while leaving your brew boiler on. This switch is located on the right side of the most recent model of the machine near the illuminated power switch.

  • 1 Single and 1 Double Spout Portafilter with insert baskets

The tried and true construction of the Alex Duetto has been brought to their latest model, the Alex Duetto IV Plus. T.E.A Coated insulated copper boilers ensure maximum heat retention, much greater than stainless steel boilers, as well as a considerable reduction in the price! With a copper boiler, you’ll also have less susceptibility to chloride stress corrosions.

Some seemingly minor changes were made that increase longevity. They have inverted the motor position, now the motor is located above the pump. The pump can not leak on the motor . In addition to the inversion of the motor position, the Alex Duetto IV Plus has an easy-to-access pump adjustment screw. This adjustment is accessible on the left side and adjusts your pump pressure with the turn of a screwdriver.

Izzo has reinforced the front panel to reduce flexing which further contributes to this substantial machine’s commercial build quality for your home.


Each boiler on the Alex Duetto IV+ is PID controlled to the degree in either Fahrenheit or Celsius which is easily changed right on the controller itself. Also integrated within the PID is a shot timer. 


With almost all of our home espresso machines, they carry a two-year warranty This two-year warranty provides nearly everything that you’d need to fix flaws that may arise during this time period. After that time, however, you are not left out in the cold! Our service technicians are always available by phone for you.
