|H.||The cleaning cycle is not complete. Rinse the portafilter and filter basket thoroughly to remove any tablet residue before using.|
Cleaning the Steam Wand
Cleaning the steam wand should be done every time it is used to texture milk.
- Immediately after texturing milk, wipe the wand with a damp cloth, ensuring all of the milk/froth at the bottom of the wand is removed.
- The steam wand should also be purged by lifting the STEAM LEVER for a few seconds allowing steam to blow out through the tip and into the drip tray.
- If any of the holes in the top of the steam wand have become blocked, ensure that the STEAM LEVER is in the CLOSED position and clean the holes out using the pin on the end of the included cleaning tool.
- If the steam wand remains blocked, remove the tip with the spanner opening on the cleaning tool and soak the top in hot water for 30 minutes. Screw the top back onto the steam wand using the same spanner opening in the cleaning tool and purge again.
Cleaning the Filter Baskets and Portafilter
The filter basket and portafilter should be cleaned after every use.
- For cleaning after every use, run the filter basket that has been used, as well as the portafilter, directly under hot water for a few seconds. This should remove any residual oils from the extraction.
- If any of the holes in the filter baskets become blocked, dissolve a cleaning tablet in hot water and soak the filter basket and portafilter in the solution for 20 to 30 minutes. Rinse thoroughly.
Cleaning the Shower Screen
The Shower screen and group head should be wiped after every use to remove excess coffee grounds.
- The group head interior and shower screen should be wiped down with a damp cloth after every use to remove any ground coffee particles that may remain after extraction.
- Periodically purge the machine with hot water with the filter basket and portafilter in place but with NO ground coffee added. This will aid in rinsing out any residual coffee oils.
Cleaning the Drip and Storage Tray
The drip tray should be removed, emptied and cleaned after each use as well as whenever the indicator is showing ‘EMPTY ME!’.
- When the EMPTY ME! indicator shows in the drip tray or after any purging, the drip tray will need to be emptied and cleaned.
- Remove the grill from the drip tray and wash both in warm soapy water. The EMPTY ME! indicator can be removed and cleaned separately as well.
- Both the drip tray and the storage tray can be removed and cleaned with a soft damp cloth. Do not use harsh abrasive cleaners, pads or cloths as these can scratch the surfaces.
Cleaning the Outer Housing and Cup Warming Tray
The outer housing and cup warming tray can be cleaned with a soft damp cloth. Polish with a soft dry cloth. Do not use abrasive cleansers, pads or cloths which can scratch the surface.
Using the Allen Key
The Allen Key is used to replace the silicone seal surrounding the shower screen. Over time, this seal will show wear and tear and leaking may occur around the portafilter. This will need to be replaced and there are just a few steps needed to do so.
|1.||Press the POWER button to turn the machine off and unplug the cord from the power outlet.|
|2.||Remove the water tank and drip tray from the machine, taking care if they are full.|
|3.||Clean any residual coffee from the screw in the center of the shower head.|
|4.||Insert the shorter end of the Allen Key into the center of the screw. Turn counter-clockwise to loosen the screw.|
|5.||Once loosened, carefully remove and retain the screw, shower screen and dispersion plate. Wash the shower screen and dispersion plate in warm soapy water then dry thoroughly.|
|6.||Remove the silicone seal with your fingers or a pair of long-nose pliers. Insert the new seal, flat side first, so the ribbed side is facing you.|
|7.||Re-insert the dispersion plate first, then the shower screen, and finally the screw. WIth your fingers, turn the screw clockwise for 2 or 3 revolutions. Insert the Allen Key to tighten the until the screw is flush with the shower screen.|
|8.||Re-insert the drip tray and rear water tank.|

If spurting or leaking of the coffee can be seen around the portafilter while it is locked in place, while brewing a shot, here are some things to consider.
- Not all handles and group-heads are compatible though they may feel tightly sealed. Only the 58mm portafilter handle that came with your specific machine should be used. Using an aftermarket or different version then what was provided with your unit could cause an issue. If the espresso machine being used has been replaced, serviced or additional handles have been purchased, this is most likely the issue. If not, please contact our support representatives via phone or the web and we will help identify if the handles are compatible.
- The seal inside the upper group-head may be wearing or be cracked. This can happen after using the espresso machine for a good amount of time and is easily replaced. Please contact our support representatives via phone or the web and we will be happy to assist with diagnosing the root cause.
When there is an issue with the Dual Boiler™, most of the time an alert will flash on the LCD screen or an LED light will come on. Below is a listing of what those mean and how to rectify them.

- The Roast – The darker the roast, the glossier the surface of the beans will be. This means that the oils have been roasted to the surface and these will need to be used fairly quickly to prevent evaporation of the oils. Letting glossy beans wait in unsealed containers will dry them out and, when brewed, will produce a result that is lacking in the normal, rich créma.
- Freshness of Grind – Pre-ground coffee will also allow more of the oils to evaporate before they can be used. The results of using pre-ground espresso that has a roasted on date that is very much in the past is that the espresso will be lacking the full créma, may be less aromatic, and may come out watery, thin. Keeping pre-ground espresso in an air-tight container and making sure that it is finely ground to provide the most surface area for the water to pull out the remaining oils can help with these issues for pre-ground espresso.
- Coarseness – The grind of the coffee is very important. Twenty coffee beans ground on a very coarse setting will take up more room then twenty beans ground on an incredibly fine setting. If darker, oilier beans are used, the grind will need to be fine to make sure that the highest amount of oils are utilized during extraction. Milder roasts will not need to be as fine in order to get the same quantities of oil and flavor intensity. If the beans are older, the grind, again, will need to be a bit finer in order to make sure the most oils possible are extracted. However, too fine of a grind can cause the water to only drip out during extraction, making the espresso taste a bit burnt. Too coarse and the water will flow out too quickly, leaving the espresso weak.
- Tamping Depth – The tamping of the grounds is the next coffee factor. Depending on the coarseness of the grind being used, more or less coffee may need to be added to the portafilter. A general guide is that, once tamped, the coffee grounds should be about 1/8th of an inch below the top edge of the portafilter. For a visual, that’s about this long _. It should be roughly this low to allow the coffee to be close enough to where the water comes out so that a good pressure seal can be created easily but far enough away that the grounds are not pressing up into the shower head that the water is coming out of, effectively blocking them. The tamp of the grounds should force the grounds down that 1/8th of an inch below the top edge of the portafilter. If the coffee is pressed too far down, the water will just flow through it quickly. If it is too close to the shower head, it will barely drip out.
- Tamping Pressure – Tamping pressure is also a factor in the extraction. Packing down the grounds as hard as possible will not allow enough room for the water to flow through. Not packing down the grounds tight enough will produce weak results as the water will flow through too quickly. The general idea is to put around 30 lbs of pressure on the grounds when tamping. Getting the entire section of ground coffee compressed with just a tamp is impossible, however, 30 lbs of pressure will compact the upper portion enough to force the water to around 9 bars of pressure to get the fluid through the grounds. While the upper portion provides the initial resistance to make good créma, it’s the slightly looser grounds at the bottom that keep the flavor pressure up. Once water hits the grounds, they expand and while the upper portion is the initial resistance, once the bottom portion expands with moisture, it, too, provides similar resistance and pressure. 30 lbs will compact the upper section of grounds to make the rich aromatic créma generally sought.
- Non-Fat Milk – When frothing milk, the lower the fat content, the ‘bigger’ the foam. The results will be a lot of foam with larger bubbles in it. Non-fat milk is best at this. Due to a lack of fats, the liquid is able to create and maintain larger fluffier froth/bubbles. If the goal is ‘microfoam’, the smaller-bubbles, more silky textured foam then fat is needed. If the froth is not the consistency that is desired, using a higher fat content milk is suggested.
- Low-Fat Milk – The higher the fat content of the milk, the higher the temperature will need to be in order to create the foam. Low-Fat or 2% Milk is s mixture of the silky fat enhanced milk and the bubblier non-fat milk. It will take longer to get the quality and volume that is intended with a higher fat content but the results will be closer to the silky texture
- Whole Milk – Whole Milk is about 4% fat content and will take a higher temperature and longer heating/frothing time in order to reach the resulting silky foam. The volume of the milk will increase as the steam is added but it will take a bit of time before that silky textured foam results.
Lack of Steam
- If the steam wand is not producing steam or not enough steam, it’s important to make sure that the heating light is not lit while turning on the steam.
- Make sure that the steam wand tip is not clogged. Using the needle end of the cleaning tool, slide the needle into the hole at the tip of the steam wand, breaking through any clog that may be there. Once done, if the heating light is not on, turn on the steam and allow it to run for 10 seconds.
- To prevent the steam wand from being clogged, after each use, turn the steam on and allow it to run for 10 seconds, steaming into the drip tray to clear any milk that may be inside the tip from the last frothing done.
- It is important to note that when the steam is initially started each time, a small amount of water will drip out. The water that remains in the steam wand after steaming will cool and condense back from steam into water and this will be forced out before the steam comes out.
- When descaling the espresso machine, make sure to run some of the solution through the steam wand. Since steam and water do come out of the wand, it, too, will have mineral deposits and the descaling will help in preventing clogs.
- The Portafilter and Filter – When the espresso is brewed, the temperature of the liquid coming out of the machine, before it hits the coffee, is around 200°F (generally between 195°F and 205°F). While some heat loss is expected and even desired to get the espresso to a comfortable drinking temperature, too much can alter the flavor of the coffee. If the espresso is cooled too much during brewing, the flavor can be sharper or a bit bitter. To help in preventing this, we recommend that the portafilter, with the metal filter inserted, be locked into the brew head with no coffee in it and a single shot be run through it. This will heat up the metal to a temperature much closer to the water brewing temperature and prevent that sour flavor. Once the water is through, remove the portafilter, dry it thoroughly, and add in the coffee to begin the shot.
- The Cup – Once the water leaves the portafilter, it is falling down and into the cup. If the cup is cold it can greatly reduce the temperature of the espresso prior to drinking. Between 160°F and 180°F is considered a comfortable drinking temperature. However, the hot espresso entering a cup that is significantly lower in temperature then the water brewing temperature of around 200°F can cause the liquid to drop below that comfortable level. This can cause the espresso to taste off and not be at all appetizing. We recommend that when the portafilter is being pre-heated with a single shot with no coffee, the water falls into the cup to be used for the drink. Let the water stay in the cup, heating it, until immediately before extracting the shot.
- Other Temperatures – If the cup has been warmed as well as the portafilter and filter, please note that it is also vitally important to descale the espresso machine. Mineral deposits can build up along the thermo-block heater and prevent the full transfer of heat to the water. We recommend that, with regular once a day use, the espresso machine be descaled every 2 to 3 months. If hard water is being used or the espresso machine is being used more often, the time can be lessened to every 1 to 2 months between descalings.
Using the right water is essential to achieving the best flavor from coffee and making sure the machine operates without interruption. We do not recommend using highly filtered or demineralized water such as reverse osmosis, ultra filtered, demineralized or zero-filtered waters. The machine is not designed to operate with these kinds of filtered water as there is too little or no mineral content which is required for the sensors within the machine to operate. These types of waters can also alter the taste of the coffee from what one would normally expect.
If these types are waters must be used, we recommend adding in a small bottle (6oz) of spring or tap water when filling the water tank to provide the minimal content of minerals required for the machine to operate without hassle.
