Frequently Asked Questions - Linea Mini La Marzocco

How to adjust the group water temperature?

Turn the mechanical potentiometer located on the front panel (see Figure 5 in the manual) to adjust the temperature. Wait a few seconds after turning to stabilize the temperature. To lower it faster, run water through the group.

What to do if the machine does not turn on?

Check that the main switch is in the I position. Make sure the machine is properly plugged into a working outlet. If the problem persists, contact customer service.

How to clean the steam wand?

Immediately after use, wipe the wand with a damp cloth and release a small burst of steam. If milk residues persist, dip the tip in hot water and then wipe. Do not leave deposits that would alter the taste.

Why is the espresso not coming out?

Check the water level in the tank (blue light on) and that the tank is correctly inserted. The grind may be too fine or the shower screen clogged. Remove and clean the shower screen. If nothing works, contact customer service.

How to adjust the water pump pressure?

Remove the top and bottom drip trays to access the adjustment screw. Loosen the lock nut, then turn the screw clockwise to increase pressure or counterclockwise to decrease. Pressure should be adjusted during extraction with coffee in the portafilter (recommended value: 9 bar).

What do the indicator lights mean?

Red light flashing (1s on/1s off): heating in progress. Red solid: temperature reached and connected to Wi-Fi. Red flashing (3s off/1s on): standby. Blue flashing: water tank low or absent. Blue solid: water present.

How to connect the machine to Wi-Fi?

For the first connection, use the La Marzocco app available on Play Store and App Store. Follow the instructions in the app. Afterwards, the machine will connect automatically. To disconnect, remove the tank, wait for the blue light to flash, then operate the paddle lever 5 times in 10 seconds.

Why is the coffee too cold?

Make sure the red light is solid (machine at temperature). Increase temperature via the mechanical potentiometer. Preheat the portafilter and cups. Check that the cup is warm. If the problem persists, contact customer service.

How to maintain water quality?

Use filtered water with hardness between 70 and 100 ppm, pH 6.5-8.5 and chlorides < 30 mg/l. Test the water with the provided analysis kit. If necessary, install a suitable filtration system, using the La Marzocco online water calculator.

What to do if steam does not come out?

Check that the steam wand is not clogged. Check the steam boiler pressure on the left manometer (should be between 1.3 and 2 bar). Check that the main switch is on I and the machine is plugged in. If everything is correct, contact customer service.

In order to enable you to check if your water supply is within the suggested ranges, La Marzocco machines will be equipped with a quick water test kit (see image below) including 6 test-strips and instruction cards. The parameters

that you can measure are Total Hardness, Total Iron, Free Chlorine, Total Chlorine, pH & Total Alkalinity, Chlorides. Ideally, you should perform a test on the water BEFORE the water treatment system and again AFTER the water system in order to verify if this is actually matching our

suggested ranges.

Once the test has been performed, learn which treatment system is most appropriate for your particular water supply by filling out the online water calculator on our website: LA MARZOCCO WATER CALCULATOR (http://www.lamarzocco.com/water_calculator/).

2) Connect espresso machine to power supply.

Connect the espresso machine to a power supply that is rated in accordance with the serial plate on the espresso machine.

3) Filling the boilers with water.

Complete the following steps to properly fill the boiler tanks:

Steam boiler: Turn the main switch to position "1", the steam boiler will then automatically fill to a predetermined level. When the correct water level in the steam boiler is reached, the machine will automatically stop filling.

Line drawing of a kitchen appliance with a door and base (no text or symbols)

NOTE: It may be necessary to re-fill the water reservoir during this process.

Integrated brew group: The water flows inside the Integrated brew group directly when the water pump is activated. When the linea mini is turned on the electronics will activate the water pump to fill both boilers.

4) Verify filling of boilers.

The installation is now complete and the espresso machine should be heating to the operating temperatures.

Brewing after first installation

Once the first installation procedures are finished, before proceeding with brewing coffee, hot water and steam, please follow these steps:

- Engage the portafilter by inserting it into the group head and rotate the handle from left to right. Once the portafilter is inserted properly, you can move the paddle on the left side to start the flow of water through the portafilter. Brew water through the group for at least two minutes.

• Being careful to avoid burns, turn on steam wand for at least one minute.
• Turn on the hot water valve for the time necessary to allow at least 1 liter of water to be brewed.

5) Waiting for the espresso machine to heat to operating temperature.

During this time, the pointer of the Integrated brew group pressure gauge may reach as high as 12 bar. This may happen anytime that the heating element is in the "on" condition. If the pressure exceeds 12 bar then it will be necessary to adjust the expansion valve in such a manner that the pressure never exceeds 12 bar. In normal operating conditions, the Integrated brew group pressure gauge can read anywhere from 0-12 bar. When brewing, the pressure should be set to approximately 9 bar.

The machine is ready to brew water when the power indicator light (red) is ON. When the machine is warming up the power indicator light (red) is flashing.

NOTE: As the steam boiler reaches operating temperature you may hear air and steam escaping from the boiler. This is a normal sound. As the water boils, air in the boiler is replaced by steam and exits through the vacuum breaker. As the boiler get closer to operating temperature the vacuum breaker closes and the steam is no longer able to escape. This process allows the air in the steam boiler to escape and to be replaced by water vapor.

7) Adjusting the expansion valve.

The expansion valve is a component that limits the maximum pressure in the Integrated brew group. Heating the integrated brew group causes the water within to expand. Since the integrated brew group is completely saturated, the expanding water causes an increase in pressure within the boiler. Without a safety device the increase in pressure could cause a rupture in the boiler. The pressure in the integrated brew group should never exceed 12 bar. The valve is

hot, so, using adequate protection, rotate the expansion valve clockwise to increase pressure. To decrease pressure, rotate the expansion valve counter clockwise (see the following diagram).

Increase pressure Decrease pressure

Figure 2 - Expansion Valve Adjustment

8) Adjusting water pump pressure.

The water pump is factory set at 9 bar pressure. If it becomes necessary to change the pressure please use the following procedure:

1. Remove the top tray and the lower tray.

2. Locate the water pump adjustment screw and loosen the lock nut.

3. Adjust the water pump pressure to the desired measurement.

4. Rotate clockwise to increase pressure and counter-clockwise to reduce pressure.

NOTE: The water pump pressure should be adjusted when the machine is operating and coffee is present in the portafilter.

5. Operation

WARNING

The integrated brew group and steam boiler contain water at elevated temperature. Water temperature over 125°F / 52°C can cause severe burns instantly or death from scalding (integrated brew group 200°F/93.3°C - steam boiler 260°F / 127°C).

WARNING

The machine must not be dipped in, nor splashed with, water in order to clean it. For cleaning operations, please follow the instructions listed below very carefully.

WARNING

This machine is designed only for preparing coffee and hot drinks.

WARNING

To avoid the risk of injury, do not open the brew chamber during the brew process.

1. Installing the portafilter.

Install the portafilter by inserting it into the integrated brew group and rotate the handle from left to right. Once the portafilter is inserted properly, you can move the paddle handle from right to left to start the flow of water through the portafilter. It is important that the portafilter is at operating temperature prior to filling with coffee.

Filter basket Spring Portafilter O-Ring gasket Double snap-on spout Figure 4 - Portafilter

Figure 4 - Portafilter

Allow hot water to pass through the empty portafilter for a few seconds before the brewing process to pre-heat the portafilter.

NOTE: It is important to leave the portafilter locked in the espresso machine when not in use. The portafilter must remain heated for the brewing process to function correctly.

1. Brewing coffee. It is now possible to remove the portafilter to make a coffee beverage. Place some ground coffee in the portafilter basket using the single or double basket. Press down on the ground coffee with the supplied tamper and install the portafilter on the linea mini. Move the paddle handle from right to left to begin brewing (see Fig.1 page 8).

You can adjust the coffee brewing water temperature rotating the ring of the mechanic potentiometer (see Fig.5 page 14)

It is recommended to wait for a few seconds until the desired temperature is achieved.

If you want to decrease the temperature, it is recommended to dispense water from the group for a few seconds to speed up the process.

图5 - Mechanical Potentiometer

NOTE: Some users believe it is important to allow water to pass through the integrated brew group prior to installing the portafilter to flush any remaining coffee oils and particles from the integrated brew group. Some also flush just after brewing for the same reason. Please experiment to make the best possible procedure for your coffee. There are many techniques for brewing espresso. You can find instructions for many techniques on websites, blogs and forums.

3. Dispensing steam.

In order to allow for any condensed water in the wand to be released ALWAYS allow some steam to be discharged by turning on the valve before inserting the steam wand into the pitcher of liquid to be heated. Dip the steam wand into the liquid to be heated. Rotate the steam knob to activate the steaming process.

The steam valve has a variable flow control. The steam will transfer heat to the liquid raising its temperature. Be careful not to allow liquid to overflow in order to avoid severe burns.

Steaming milk for cappuccinos and other beverages is very easy but making it just right requires some skill. Please experiment with various techniques to find the best method for your milk. You can find many discussions about the steaming of milk on the internet.

NOTE: It is important to have a sufficient volume of liquid in the steaming pitcher. Therefore if you intend to steam small amounts of milk it is necessary to use a small pitcher. If you intend to steam larger quantities of milk then it is necessary to use a larger steaming pitcher.

Using too little milk in a steaming pitcher can allow the milk to be "blown out" of the pitcher. A good rule to follow is to fill the steaming pitcher only half full of liquid.

NOTE: In order to prevent the heated liquid from being sucked back into the steam boiler it is recommended that you purge the steam system after heating any liquid. Purge the system by opening the steam valve for a few seconds to allow steam to escape to the atmosphere from the end of the steam wand.

4. Dispensing hot water.

You may dispense hot water by using the hot water nozzle. To dispense hot water rotate the left knob (see Fig.6 page 14).

This knob commands the hot water delivery.

Hot water knob Figure 6 - Hot Water Knob

5. Connect/disconnect the coffee machine to/from the WiFi network.

Use the app for the first connection to your WiFi network.

Subsequently, when the coffee machine is turned on, it will automatically connect to the WiFi network.

For disconnecting the coffee machine from the WiFi network, remove the water tank, make sure that the blue LED flashes, operate 5 consecutive times the paddle lever within a time of 10 seconds. Now the machine is disconnected.

To restore the connection of the machine, just turn it on again using the switch.

6. Key Features

WARNING If the above-mentioned instructions are not adhered to the manufacturer cannot be held responsible for damage to persons or things.

1. Hot water dispensing.

Hot water may be dispensed from the Hot Water Wand on the left side side of the machine. This is accomplished by rotating the left knob (see Fig.6 page 14).

2. General notes for coffee preparation.

The portafilters must remain heated since they are at the lowest position of the group itself, and they are partially isolated from the group due to the rubber gasket between them. This can be accomplished by leaving the portafilters installed in the machine when not in use. The portafilter may also be actively heated by rotating group activation paddle to flush hot water through the portafilter then turning off the water flow.

3. Coffee grind.

The size of the coffee granules is extremely important in preparing a good cup of coffee, along with the type of coffee blend used. The ideal grind can be determined by making various coffees using the amount of ground coffee that you would normally use for each cup (we recommend at least 6g). The best grind is that which allows coffee to flow out from the portafilter spouts neither too slowly, drop by drop, nor too quickly. A general rule is that a double dose should dispense approximately 60ml/2 fluid oz. of espresso in approximately 25 seconds. This time may be adjusted by varying the coarseness of the grind.

N.B.

If the machine has not been used for more than 8 hours or, in any case, after long periods of being idle, in order to use the machine to its full potential it is necessary to perform some cleaning cycles before brewing beverages as follows:

- Group: with the portafilter engaged in the group brew water through it for at least two minutes.

• Being careful to avoid burns, turn on the steam wand for at least one minute.
• Turn on the hot water valve for the time necessary to allow 1 liter of water to be brewed.
• If using the machine with water reservoir, change the water in the reservoir daily.

If the machine is not going to be used for long periods of time, it is advisable to follow these safety indications:

• Disconnect the machine from the water mains or interrupt the water connection via a mains tap.
• Disconnect the machine from the electrical mains.

7. Preventative Maintenance and Cleaning

WARNING

Jets of water should not be used to clean the machine, nor should it be placed where water jets are used.

WARNING

Do not remove the filter holder while relative group is brewing hot liquids. The integrated brew group contains water at elevated temperature. Water temperature over 125°F / 52°C can cause severe burns instantly or death from scalding.

WARNING

The machine must not be dipped in, nor splashed with water in order to clean it. For cleaning operations, please follow the instructions very carefully.

WARNING

The expansion valve can discharge water as hot as 200°F / 93°C. Adequate protection for handling this component is needed before attempting to adjust.

WARNING

This machine is designed only for preparing coffee and hot drinks.

Cleaning (Daily)

1. Cleaning the diffuser screen and diffuser screw.

During the discharge operation (subsequent to coffee brewing), small amounts of coffee grounds may slowly build-up on and obstruct, even partially, the diffuser screen. Turn off the machine and remove the diffuser screen by unscrewing the diffuser screw. Soak in detergent powder liquid following the instructions of detergent manufacturer. Rinse thoroughly with clean water puro caff. Install and run hot water through the group head several times with the screen installed.

2. Cleaning the brewing system.

Insert the blind filter into to the portafilter and put the correct amount of espresso cleaning product (following the product's instructions) into the filter, engage the portafilter into the Integrated Brew Group.

Figure 7 - Integrated Brew Group

• Move the group activation paddle for said group, as if you were making a regular cup of coffee. Stop the water after about 15-20 seconds.
• Start and stop the group several times until you notice clear water being released instead of soapy water when you remove the portafilter. Do not remove the portafilter when group is dispensing water.
• Rinse the group using a normal filter in the portafilter, by running hot water through it several times.

3. Cleaning the body.

Wipe the stainless steel surfaces with a soft, non abrasive cloth in the direction of the glazing marks, if any. Do not use any alcohol or solvents whatsoever on painted, imprinted, or plastic parts in order not to damage them. Clean the side panels using a soft cloth. Clean only with a damp soft cloth or possibly soaked in warm water and mild soap.

4. Cleaning the steam nozzles.

Steam nozzles must be cleaned immediately after use with a damp cloth and by producing a short burst of steam so as to prevent the formation of deposits inside the nozzles themselves, which may alter the flavor of other drinks to be heated. If milk residue is present on the steam wand, soak the tip in a container of hot water, then it will be possible to wipe the tip clean. Repeat process if residue remains.

5. Cleaning the hot water nozzles.

Hot water nozzles must be cleaned periodically with a damp cloth soaked in water and/or mild soap.

NOTE: This cleaning schedule is based upon a moderate to average use (5-20) cups per day. If machine use is less than moderate then this schedule may be adjusted accordingly.

1. Clean the water reservoir and the drain box: The water reservoir needs to be cleaned periodically to ensure that no algae forms on the inside surfaces. To clean, first remove the water reservoir from the machine. Disconnect the clear plastic water intake hose. Hand wash each part with water containing mild soap.

7. Steam boiler draining.

Yearly, we recommend to fully drain the steam boiler by means of the specific drain cock located on the side of the boiler or under the boiler.

2 Remove/Open the fill cover and fill the reservoir with filtered water. Slide the reservoir back into position and replace the drain box. Make sure the drain box is inserted fully. The water reservoir must make contact with the level indicators on the rear side.

NOTE: The linea mini is configured to work with the water reservoir.

1 Unpack espresso machine and set on a level surface. Ensure all accessories are included with shipment. Check for any visible damage to espresso machine.

WARNING

The coffee machine must be placed in a horizontal position on a counter higher than 90 cm from the ground.

Drain box Water reservoir Fill cover

IMPORTANT NOTE: The drain box must be installed correctly for the machine to function properly. The drain box has two magnets that mate with two alignment grooves on the base of the linea mini. When installing the drain box, ensure that the alignment magnets are inserted into the alignment grooves. It may be necessary to push slightly on the front of the drain box to achieve proper alignment. When the machine is ON and the water tank is full, the water reservoir indicator light (blue) is ON; if the water tank is empty the water reservoir indicator light (blue) is flashing. Alignment magnets and grooves Alignment grooves Connect the power cord to a power supply capable of supplying: 230VAC and 8,3 Amps (for the 220-240V version) or 115VAC and 14 Amps (for the 115 V version).

WARNING

The manufacturer declines any responsibility for any event leading to liability suits whenever grounding has not been completed according to current local, national, and international regulations and electrical codes, or if other electrical parts have been connected improperly.

Turn on power by pressing the main power switch. The main power switch may be found on the left rear of the machine.

Next it will be necessary to check the expansion valve. As the integrated brew group heats to operating temperature the pressure in the integrated brew group will rise. There is an expansion valve behind the drain tray that allows some water to escape during this process to limit the maximum pressure in the integrated brew group to 12 bar. Please monitor the integrated brew group pressure gauge during the initial heating process. You should notice the gauge approach 12 bar and stop. If the pressure gauge does not reach 12 bar or if the pressure gauge rises above 12 bar, then it will be necessary to adjust the expansion valve. Please follow the next step to properly adjust the expansion valve.

Increase pressure Decrease pressure CleanZoCCD

Please follow this procedure if it is necessary to adjust the expansion valve. First remove the drain box to access the expansion valve. The expansion valve protrudes through the sheet metal, has the shape of a hexagon, is brass in color and 18 mm (tool). The valve will be hot, so, using adequate protection, in order to adjust the expansion valve rotate the valve clockwise to raise the pressure and counterclockwise to reduce the pressure. It may be necessary to use a spanner to rotate the expansion valve in 1/4 turn or less increments until the desired pressure is achieved. Replace the drain box after each adjustment to ensure the machine is operating correctly.

WARNING

The expansion valve can discharge water as hot as 200°F / 93°C. Adequate protection for handling this component is needed before attempting to adjust.

You may also monitor the steam boiler heating progress by watching the steam boiler pressure gauge. The steam boiler is set at approximately 2.0 Bar of pressure at the factory.

Once the pressure gauge reaches this point the heating will stop.

When brewing, the integrated brew group pressure should be between 8-10 bar. The steam boiler pressure should be set at 2 bar but can operate at any setting between 1.3 bar and 2 bar.

The temperature of the brewing water is measured at the most critical point in the integrated brew group where temperature fluctuation is the greatest.

This parameter is set at the factory at a preset nominal temperature. The temperature of the water exiting the integrated brew group is held constant by means of the mass of the group casting. Even though the temperature of the water may vary slightly, the temperature of the water exiting the group is constant.

To properly calibrate the temperature of any espresso machine it is important to measure the temperature of the water exiting the group by means of an external temperature measuring device.

It is possible to regulate the pressure of the steam boiler by pressure switch.

Rotate the screwdriver clockwise to increase the pressure, vice versa to decrease.
