The newly unveiled Izzo Alex Duetto IV Espresso Machine is the much anticipated follow up to the Duetto 3.0 and 3.0SS. It may feature the same aesthetic appeal, but it boasts a plethora of internal upgrades.

Version 4 found a way to eliminate previous concerns that water might get into the motor through the pump by inverting the motor position. It features a new PID that integrates a shot timer, which allows control on the length of the shot to achieve great tasting results. With the small cutout at the bottom side panel, the pump can be adjusted from the outside, without having to disassemble the machine. At the bottom of the machine are drain plugs for both boilers and easy access points to the heating elements. The chrome-plated gicler valve and mushroom have been equally upgraded to stainless steel to avoid corrosion.

Ugrades from the Alex Duetto 3.0:

  • The pump has been made even quieter and the clearance has been increased (to 3.5 inches) to allow taller cups.
  • Inversion of the motor position - The motor has been installed over the pump. (eliminates the concern that the pump could leak and water get into the motor)
  • New PID with shot timer - Timer now integrated into PID. (allows you to control the length of the shot and to get the best results)
  • Pump adjustment from outside - Thanks to a small cutout in the bottom side panel, it is possible to adjust the pump without dissembling the machine.
  • Drain plug in both Boilers - In order to facilitate the drainage of boilers, both boilers have a drain plug in bottom of the machine.
  • Heating Element Access - Easy access points in the bottom of the machine, to change the heating elements without dissembling the machine.
  • Gicler Valve and Mushroom in stainless steel.(no longer have concerns about corrosion or flaking from chrome plated gicler and mushroom)
