Alex Duetto 3.0 Espresso Machine Introduction First of all, thank you for your business! You are going to love your new Alex Duetto 3.0 espresso machine.
Alex Duetto 3.0 Espresso Machine First Time Set Up – Reservoir Mode – Continued Pull the drip tray out to expose the 2 switches shown in the picture below. Make sure the lever on the right is in the RESERVOIR position and the Alarm switch is also ON. Before plugging the machine in, verify the steam and hot water knobs are closed and the brew lever should be pointing straight down. Plug the machine into a 3 prong 120V grounded outlet.
Alex Duetto 3.0 Espresso Machine First Time Set Up – Plumbed In Mode Before hooking the machine up to a water line test your water for hardness using the provided test strips. If your water is above 3 grains of hardness then a softening system should be installed to prolong the life of the machine. Even if your water is soft it is still recommended to have either a sediment or carbon filter installed to protect your machine from any sediment or debris that can be found in the water.
Alex Duetto 3.0 Espresso Machine First Time Set Up - Plumbed In Mode – Continued Turn the main power switch to the on position. The pump will come on to start filling the boilers. Whenever the boiler fills the PID display will turn off to protect the heating element. After the pump has turned off then raise the brew lever until you have water coming out of the group head and then lower the lever.
Alex Duetto 3.0 Espresso Machine Normal Operation Reservoir The reservoir is located in the back of the machine under the cup warming tray. The reservoir should be filled with cold softened water only. The reservoir can be cleaned with mild dish detergent and should NOT be used in a dishwasher. The water reservoir is equipped with a magnetic float to detect the water level.
Alex Duetto 3.0 Espresso Machine Normal Operation - Continued Pressure Gauges The top gauge is your boiler steam pressure. When the heating light turns off the boiler is up to pressure and should be around 1.2 – 1.5 bar. If the steam boiler power switch is turned off then the steam gauge will not show any pressure. The lower gauge is your pump pressure. When the pump is not engaged the gauge will show the line pressure from your water supply.
Alex Duetto 3.0 Espresso Machine Normal Operation – Continued Switches On the right side on the base of the machine there are 2 power switches. The larger lighted switch in the back is the main power switch and will illuminate when the machine is turned on. The smaller black switch in front of the power switch can be used to turn the steam boiler on and off independently from the coffee boiler to conserve energy. Behind the drip tray there are 2 switches.
Alex Duetto 3.0 Espresso Machine PID Controller The PID controller‟s display will cycle back and forth to show the current temperature of each boiler. The position of the decimal point indicates which boiler the temperature is being shown for. The picture to the right shows which boiler is represented by which decimal point. Setting Temperature With the machine turned on press and hold both arrow keys until the display reads T1 then release the keys. T1 is the coffee boiler temperature.
Alex Duetto 3.0 Espresso Machine Advanced Settings And Modes Warning: These instructions allow the user to change the machine from 15 amp to 20 amp mode. This should only be done if a 20 amp circuit is available. Operating the machine in 20 amp mode on a 15 amp circuit poses a serious fire hazard and should never be done. The manufacturer and/or its distributors assume no liability for failure to follow this warning.
Alex Duetto 3.0 Espresso Machine Brewing Espresso First let me begin by explaining the three main variables of preparing great espresso. 1. Quantity of ground coffee 2. Tamping 3. The grind Quantity of ground coffee - Loosely fill the basket slightly mounding over the top. Then lightly run your finger arched across the basket from left to right, right to left, front to back, and then lay your finger flat on the basket and go from back to front to remove any excess coffee.
Alex Duetto 3.0 Espresso Machine Steaming Milk – Basics First, let‟s talk about some of the things you need to learn in order to become „barista-like‟ in your techniques. Milk – Whole milk works best to steam, both in technique and in flavor! Lower fat milks contain mostly water which will not foam well and will be almost tasteless when steamed. After all your hard work you will be left with a less than desirable tasting beverage.
Alex Duetto 3.0 Espresso Machine Steaming Milk - Technique As you face your espresso machine, point the steam arm over your drip tray and open up the steam knob in order to purge out any unwanted water that may have collected inside the wand due to condensation – you do not want that added to your delicious beverage! Next, position the steam arm so it is facing directly toward you and slightly angle it 45 degrees from the base.
Alex Duetto 3.0 Espresso Machine Helpful Tips and Information When turning the steam knob off, always keep the tip under the surface of the milk for approximately 3 seconds. If you pull it out too soon, you will destroy the nice velvety micro-foam. After removing the steam wand from the milk, position it over the drip tray and then open the steam valve for 1-2 seconds to clean out any trapped milk inside the tip and then wipe it down with a damp cloth.
Alex Duetto 3.0 Espresso Machine Regular Maintenance Backflushing is a vital maintenance procedure you must follow to help keep your machine running flawlessly for years to come. There are two types of backflushing; one with plain water, and the other with espresso machine cleaner. Plain water backflushing should be done at least once a week, however if you are so inclined, feel free to backflush with plain water as often as you like. It won't harm the machine and keeps the shower screen clean.
Alex Duetto 3.0 Espresso Machine Removing The Outer Shell Warning: Unplug the machine from the outlet before removing the outer shell. Failure to do so may cause injury and/or electrical shock. The manufacturer and its distributors assume no liability for failure to follow this warning. To remove the outer shell, remove the top cup warming tray. Under the cup warming tray there are 4 phillips screws to remove and then the top panel will lift off.
Alex Duetto 3.0 Espresso Machine Group Gasket And Shower Screen Replacement The group gasket is a black rubber gasket that makes the seal between the portafilter and the group head. We recommend replacing the gasket on a yearly basis. The Duetto uses an E61 8.5mm gasket. They can be purchased from our website at the link below. http://www.chriscoffee.
Alex Duetto 3.0 Espresso Machine Gasket and Screen Removal - Continued Method 2 If the gasket and screen will not come out using the previous method then you will need a scratch awl or ice pick to remove them. Using the scratch awl or ice pick, deeply pierce the gasket and then pry it down. If the gasket is old and dried out then it will be more difficult to remove and will come out in pieces. Repeat until all remnants of the old gasket are removed.
Alex Duetto 3.0 Espresso Machine Gasket And Screen Installation - Continued Step 2 Remove the insert basket from one of your portafilters and then insert the screen and gasket into the portafilter as shown to the right. Step 3 With the gasket and screen in the portafilter, press the portafilter into the group head as shown. Apply equal upward pressure on the portafilter so the gasket goes in evenly.
Alex Duetto 3.0 Espresso Machine Descaling Descaling is the process of running a descaling agent such as citric acid through the machine to remove the accumulation of mineral deposits. If you are using softened water then it should not be necessary to descale the machine. Often times descaling can cause more problems than it solves. It can react to the minerals and foam over ruining electrical components.
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.
Alex Duetto 3.0 Espresso Machine PID Display Is Turned Off Make sure the main power switch is turned on and the outlet has power. Make sure the water reservoir is filled with cold softened water. If plumbed in make sure that the water supply is turned on to the machine. Turn the machine off for 3 seconds and then turn back on to reset. Steam Is Continually Discharged Into The Drip Tray During heat up a small amount of steam will be discharged into the drip tray.
Alex Duetto 3.0 Espresso Machine Espresso Coming Out Too Slow Or Not At All Activate the brew lever and check the pump pressure. Recommended setting is 9 bar. Adjust pump pressure if necessary. If pump pressure is good then try adjusting grind coarser. Be sure the insert basket is not over filled with coffee and you are tamping with no more than 30lbs of pressure. Espresso Coming Out Too Fast Activate the brew lever and check the pump pressure. Recommended setting is 9 bar.
