Alex Duetto 3.0 Espresso Machine

No Water From Hot Water Wand

 Make sure the steam boiler power switch has been turned on for at least 15 minutes.

 Check the upper gauge for steam pressure. Pressure should be about 1.2 bar. If the

gauge is at zero then refer to the “Not Heating” section of the troubleshooting manual.

If pressure is good then continue with steps below.

 Check the hot water knob for proper operation. Remove the end cap on the end of the

hot water knob. Check to make sure that the c-clip shown in the picture on the previous

page is attached.

Note: If the steam gauge shows normal pressure, but when you open the steam knob the pressure

immediately drops to zero then heats normally afterwards that is called a vapor lock. This is caused

by a sticking vacuum breaker valve. A replacement vacuum breaker valve can be purchased from

our website at the link below. http://www.chriscoffee.com/products/home/isomacparts/vbreakervalve

Not Heating

 Verify the machine is plugged into the outlet and the outlet has power.

 Make sure the main power switch and steam boiler power switch are both on.

 Make sure the water is turned on to the machine. If the water was off, then turn the

water back on. Turn the power switch off, unplug the machine and then wait 5 seconds

and then plug the machine back in and turn the power switch back on.

 Check the F.02 setting in the PID controller. It should be set to either 7 for 15 amp mode

or 5 for 20 amp mode.

 Check the resettable hi-limit on each boiler. The coffee boiler reset is located on the top

of the boiler. The steam boiler reset is on the bottom of the boiler which can be

accessed by removing the access panel on the bottom of the machine.

With the machine unplugged,

firmly press the red reset

button shown in the attached

pictures.
