La Pavoni Lever Safety Valve Gold Brass body code 396738 is used to replace problematic valves, which usually leads to no pressure buildup and strange sounds during heat up.

Safety valves open up at a certain pressure, if the boiler pressure should rise too much due to a pressurestat or PCB malfunction. The safety valve should be replaced if you hear it hissing, after machine has warmed up. ie reached 9 bars.

The cylindrical body of this model was often made of brass or copper (but also nickel-plated brass, Sheffield steel, silver or porcelain) and was split into two parts: the internal part (boiler) contained the water to be heated, whilst the external part (cavity) collected the coffee infusion and had a valve plug (at the bottom) or a spout (at the top).

The boiling water went through the filter with such force that the liquid hit the internal part of the glass dome and ran down the external part of the container creating a kind of fountain effect.

Small brass coffee maker patented in Paris by Alexandre Lebrun in 1838. Steam pressure operation, it was fed by a spirit burner. The pressure of the steam pushing downwards rather than up was used by Lebrun for his small, ingeniously designed coffee maker. The ground coffee was pressed down using a pestle, in a box-shaped filter at the base of the coffee pot. The cold water was poured in from above. The lid was locked with a special clamp and the pot heated by the alcohol in a little plate at the base. In just four minutes the coffee was automatically poured into the cup through the finely worked spout.

H. Eicke’s machine was patented in Berlin, Germany in 1878. Although the device was balancing and the burner had a self-extinguishing lid and it was very similar to the compensation siphons Balance system, the way it worked was completely different. In this case, the depression of the vacuum of the boiler was not used for filtering the coffee but rather the pressure of the steam which pushed the boiling water from the boiler to the filter containing the ground coffee. When all the water contained in the boiler had gone through the filter, the coffee maker tipped and the lid of the spirit burner dropped to put out the flame. In this way, the preparation cycle finished automatically.

Elegant, with refined finishes and valuable handcrafted decorations, these two Italian coffee makers produced by Invicta are made of copper-brass and nickel-plated brass and have spirit burners. Two cup capacity.

On the left, the A.G. Oikos model in nickel-plated brass produced by Fratelli Carderoni in Milan. When the water was hot, the whistle signalled that it was time to turn the special tap in order to connect up the front filter containing the ground coffee.

Various steam pressure coffee makers, all made of copper and nickel-plated iron, with spirit burners, produced in Ferrara, Italy, by Fratelli Santini bearing the Aquilas brand and by Figli di Silvio Santini bearing the Orso brand. Two to six cup capacity. Operation of this small, charming machine for home use is simple and it is easy to use. The steam pressure pushes the hot water upwards through the coffee filter and the liquid is poured out from the front spout directly into the cups or a coffee pot.

Italian-made Adele and Stella coffee makers in nickel-plated brass. One to four cup capacity. Small travel and camping coffee makers are very compact and easy to use. The spirit burner and the cups are stored at the base of the coffee maker.

Czechoslovak-made coffee maker bearing the Sport brand. Made in steel and aluminium, it has a two cup capacity and the burner is fed with fuel tablets. This coffee maker was ideal for camping and came in a special box containing all the necessary accessories (fuel tablets, small box for sugar and coffee, teaspoon and tongs for handling the boiling coffee pot) for preparing and tasting the coffee.

Group of Italian stove-top coffee makers in aluminium. On the right, there is the characteristic Columbia Cr�me produced by OMG, steam pressure and pump coffee maker, with a six cup capacity. The pump in the handle makes it possible to increase the water pressure for extracting the coffee, making a larger quantity of coffee cream, or crema.

One of the very first versions of the famous Moka Express produced by Alfonso Bialetti in Crusinallo and sold during the post-war period. It has a solid aluminium structure, is octagonal in shape and features a brass safety valve and rubber gasket between the boiler and pot. Produced in models of varying capacity, the Moka brought a radical change to how Italians drank coffee at home, offering them coffee with a new flavour and stronger, and ousting out the Napoletana coffee maker which was popular at the time. Still today, the Moka is considered an icon of Italian-made goods throughout the world.

Italian coffee makers for families in nickel-plated brass produced in the shape of the column coffee makers for bars of the period. On the left, the Snider, on the right the La Pavoni, both from Milan.

Three Italian-made Eterna coffee makers produced by the company Watt in Pavia. Made in nickel-plated brass and cast aluminium, they are shaped like the column bar machines of the period.

Elegant, sophisticated nickel-plated brass coffee makers produced in Italy by S.I.M.E.R.A.C. in Ferrara (and subsequently Milan), with a two to four cup capacity. The coffee filter is set apart from the body of the coffee maker in order to prevent the ground coffee from heating up during machine operation. The spouts pour the coffee directly into the cups resting on the tray at the base.

The TATA coffee maker-cum-alarm clock produced by Turin company G.M.P. is both curious and ingenious. Designed for those who are unable to get up in the morning without having first sipped a steaming cup of coffee, this machine pours the last few drops of freshly-made coffee into the cup at the same time as the alarm goes off.

The French-made Cafeti�re Veritas from Lyons can produce up to six cups of coffee at a time. Made of nickel-plated brass (the 1920 model), it features a characteristic fountain shape and was redesigned for the 1940 Luxe model.

This German model, Paluxette, was very popular in Germany. Produced in solid steel and chrome-plated brass, it could be altered in height using vertical runners in order to adapt to the size of the coffee pot the user had at home. The small travel version to use in the car utilized a 12 volt supply to prepare a single cup of coffee.

The Italian La Victoria Arduino from Turin was produced in steel, nickel-plated brass and Bakelite and could dispense two to three cups of coffee at a time. This beautiful machine was built in the style of the period, bearing the enamelled brass brand of the factory in full view. When the steam reached the right pressure, the upper tap was closed and the hot water pushed through the coffee in the portafilter with a ‘bayonet’ connection and straight into the cups resting on the base.

Original in shape with elegant decorative motifs embossed on the aluminium body, this large electric machine has a four cup capacity. Moreover, the tap at the base of the heater dispensed water for making tea and infusions.

Italian-made coffee pots produced by R.V. in Milan. Made in hand-hammered copper, it works by pressure operation with an electric supply. Two to five cup capacity. With an original, topical design it features fine, carefully produced finishes. The hot water, driven through the filter containing the coffee, poured straight into the cup.

Group of electrical Italian coffee makers with a copper boiler and nickel (or chrome) plated brass body, pressure operation. Two to five cup capacity. The electric cables are clad in two-coloured swab with copper and porcelain pins.

Bavaria model produced in Germany on the left, and a large machine produced in Switzerland on the right, both electric with spouts for pouring the coffee into a jug.

Group of beautiful electric Italian machines in nickel or chrome-plated brass and Bakelite. From left to right: Diana Mignon from Turin, SCM and two models produced by Neowatt in Milan.

Chrome-plated brass coffee maker produced in Italy by Turrini B.T.D.. The various parts that make up this machine, the electrical resistance, boiler and coffee filter, are held together tightly by a clip with a screw.

Before you start, fill your kettle with drinking water and bring it to the boil. Using hot water in a Moka pot avoids giving the coffee a metallic taste, which is often the result of boiling cool water in the Moka pot and “cooking” the coffee.

The first step in preparing coffee in a Moka pot is weighing and grinding your coffee beans. For a four-cup Bialetti Moka pot, you’ll need 15 to 17 grams of coffee, ground to the same fineness as you would require for an espresso machine.

Weigh and grind your coffee, then set it aside for a moment. Once your kettle comes to the boil, pour the boiling water into the bottom of the Moka pot, making sure you fill the pot to just below the safety valve.

Once you’ve spread the coffee throughout the filter, screw on the top section of the Moka pot. The hot water will have made the bottom section quite hot to the touch, so you may want to wear an oven glove or use a dishtowel for a safer grip.

After you’ve assembled the pot, put it on the stove with the lid closed and bring it to a medium heat. As the hot water in the bottom section of the pot starts to boil, the pressure will force it through the coffee and into the top section of the Moka pot.

Give the coffee a moment or two to cool down, and then pour it into your favourite coffee mug and enjoy. If you’re using a gas stove, check that the handle of the Moka pot has cooled before you pour it, as it can occasionally pick up heat from the flame.

Artistry in motion! La Pavoni Professional Manual Espresso Machine in the all chrome configuration combines classic industrial lines with maximum manual output. Take a step closer to espresso perfection with La Pavoni Professional capable of creating up to 16 mind-blowing shots thanks to the large 38 ounce boiler. Contemplate the mysteries of life while you sip one of the best shots you"ll ever pull.

The La Pavoni professional espresso maker is a a combination of style, quality and reliability. The machine is largely constructed of chrome plated brass and is built to last. The base of the espresso machine is made of steel and is triple copper and brass plated on the outside and features wood handles. The inside of the base has has a light polish to prevent problems due to moisture.The large boiler ensures that lime scale deposits have minimal effect, meaning minimum maintenance is needed.

By lifting the lever, a piston inside the group is raised, allowing water under pressure to infuse the coffee in the filter holder. The lever is then lowered, causing the piston to force the water through the coffee into the cup. The user therefore can vary the speed at which the water passes through the coffee, ensuring this latter is made exactly according to his own requirements. The machine is fitted with a steam jet interchangeable with the Automatic Cappuccino maker, for the preparation of cappuccino and hot drinks in general, and is equipped with a manometer to check the boiler pressure. The "Cappuccino Automatic" attachment ensures a perfect cappuccino every time. This device on the opening of a valve automatically sucks the milk from its container and brews it warm and perfectly frothed into the cup.

No, it’s actually much more accurate to think of the 9Barista as a great value espresso machine. Although it’s a stove top machine and the coffee is produced upwards through the basket, that’s where the similarity ends. To make real espresso you need 9 bar of pressure and about 93°C – the 9Barista has both of these, whereas a moka pot only reaches around 0.5 bar of pressure and uses water above 100°C. The real difference is in the intense flavour and texture of the espresso it can produce, topped with thick crema.

Yes, all materials in the 9Barista are safe for food contact. There is no aluminium in the machine. It is made from brass, which is then nickel plated. The nickel plating we use is a food grade high phosphorus electroless nickel plating. It’s commonly used in the food processing industry, as it has excellent resistance to attack from acids.

Other materials used are silicone rubber, which is used for the thermal break and basket cap, PTFE, which is used for the valve pin, and PEI which is used for the group insulator. All of which are safe for food contact. It’s also worth noting that the walnut handles are FSC certified.

After brewing, there will be a vacuum in the boiler. If this vacuum isn’t neutralised it will be difficult to unscrew the machine and you may dislodge your boiler o-ring in the process. To neutralise the vacuum simply lift / pull the pressure release tab on the safety valve,but only do this when it’s cool enough to touch. Running your machine under cold water will cool it down within 10-20 seconds. When you lift the pressure release tab you’ll hear a hiss, at which point the boiler will be easy to unscrew.

A good quality burr grinder that has been designed for espresso will enable you to do this. Blade grinders do not provide the necessary degree of control, so avoid using these. We recommend some grinders here.

Cleaning your machine only takes a few seconds and is best done in the kitchen sink. Give it a quick rinse after every time you make an espresso and be sure not to use any abrasive cleaning products. Water alone is sufficient. The wooden handles of the machine are not suitable for the dishwasher.

If your 9Barista is still hot, run it under the tap until it’s cool enough to grip. Then, unscrew the portafilter from the grouphead, remove the basket cap and knock out the spent grounds (a knockbox is a great addition for this part of the process). Then, press the pressure release tab on the safety valve and unscrew the boiler. Give everything a rinse and leave the parts to dry, or dry them with a towel. The handles are made from wood and should not be left wet, so we recommend giving them a quick dry with a towel.

The next trick you can use is to put your 9Barista on the stove to heat up while you grind and tamp the coffee in the portafilter. Be careful though, you’ll need to get the portafilter back on before the machine starts to deliver hot water. Only attempt this once you know you’ll be fast enough.

There are two ways to be able to tell when your machine has finished extracting; the first is that the espresso will stop rising in the portafilter. You should also be able to see and hear a final, stronger flow of steam coming from the chimney, for one to two seconds, which signals that there’s no more water in the boiler and the extraction has finished. You should turn off the heat at this point and pour your espresso straight away.

Note: if you’re using one of the original heat exchanger plates, it should only ever be heated when the 9Barista is sitting on it. If it’s pre-heated or left on the heat once the 9Barista has brewed it’s likely to separate into layers or deform. If this happens it won’t be able to transfer heat effectively and your machine won’t be able to produce espresso. It’s also important that you never cool your heat exchanger plate with water. Further guidance is available here. We recommend upgrading to our new

The heat transfer plate is designed to be used on traditional domestic stoves. For this reason we recommend that you do not use a wok burner-style gas stove or industrial stove, as these produce excess heat and can damage the plate. The heat transfer plate can be used on a medium-sized gas ring of between 2-3 inches in diameter, or a medium-sized electric ring. We mention this in our getting started guide. If using a camping gas stove, the heat transfer plate is not required.

Our machines are cast and then CNC machined to final form. Some of the surfaces are left in the as-cast condition, and so it’s normal to expect some slight variations in the surface finish. They won’t affect the performance of the machine – we like to think they make each machine unique, and reveal a bit about how they are made! If you’re concerned that your machine has marks or imperfections above what you’d expect, please send us a photo to [email protected] and we will take a look.

It’s possible you may also notice some slight watermarks on the inside on the boiler. Although perfectly safe, these can be a side effect of the plating process. We use a high phosphorus electroless nickel plating, which is a high-spec engineering grading plate not typically selected for its aesthetics. The plating will however give you far superior corrosion resistance to the chrome plating which is normally used on espresso machines. The marks should disappear if you clean them with warm soapy water or a light abrasive pad.

The 9Barista will work with pre-ground coffee, but it might not provide a great experience. A small change in grind size can make a big difference to the results, and a grinder like one of those recommended here will enable you to make those small changes quickly and easily. This is important as you’ll likely need to try a few grind settings before finding the right one for the beans you’re using. A grinder makes this very simple, and in turn makes it much easier to hit the recommended 25-30 second extraction time, which is what gives the best results with plenty of crema. Pre-ground coffee may be too coarse, which would result in watery coffee with no crema, or too fine, which would result in bitter coffee, or even no coffee at all.

We don’t currently make any additional accessories for the 9Barista, other than the tamper, although we do plan to add these in the future. The machine uses a 53mm basket, so any accessories you buy should be designed to work with a basket of that size (they’ll usually be labelled with dimensions to fit the relevant basket e.g. a 53mm dosing funnel is designed to work with a 53mm basket). If you’d like a precision basket, we sell an IMS one here.

We don’t recommend the use of a pressurised basket with the 9Barista. Pressurised baskets commonly have a hole in the centre rather than off-centre or closer to the side. With a standard espresso machine that’s not a problem as the coffee is directed downwards into a cup, but the basket in a 9Barista faces upwards, which would not make for a pleasant experience! More to the point however, we want to help you to make tasty espresso with your machine, and the best way of doing that it to pair it with a good burr grinder, which would remove the need for a pressurised basket.

Yes, this can happen. You may find that your portafilter develops a slightly blue-ish colour over time. The electroless nickel plating we use has some interesting optical properties, which we believe is due to a diffraction effect. You should notice that if you put a small amount of cooking oil on your finger tip and apply it to the dark patch, it will disappear! Over time the patterns of dark blue colours will disappear. We have done plenty of analysis on the chemical safety of the machine so there’s no cause for concern.

If you live in a hard water area, you may find that limescale deposits build up inside the 9Barista boiler and around the heat exchanger coil. Small deposits of limescale are not a problem, but if too much is allowed to form it can begin to interfere with the function of the machine. If this is the case, we’d recommend running a descaling cycle to clear it. We have instructions on how to do that here.

It’s important that these instructions are followed closely to avoid using too high a concentration of citric acid. Doing this every few weeks should ensure that your machine remains in good working order. If you notice large limescale deposits forming, or if there appears to be a restriction in the flow path through the machine, running a descaling cycle will help clear them.

The machine will work at any altitude but you may find that above around 3,000 metres the coffee it produces becomes a little sour. We have successfully brewed delicious espresso using a 9Barista at 3,000 metres (10,000ft), and some of our customers have used their machine at 4,400 metres (14,400ft), as you can see in this Instagram post.

The reason for this change above 3,000 metres is that the boiling point of water drops by around 3.5°C for every 1,000 meters above sea level. This means that as you climb, the water in the upper chamber is boiling at a lower temperature, creating an increased cooling effect on the water from the lower boiler before it reaches the coffee. For this reason we recommend that the machine works best in locations where the boiling point of water is no lower than 90°C.

If you are finding that your shots are coming out a little sour, then quite often grinding your coffee finer and aiming for a longer extraction of 30-35s can fix the issue. By giving the water more contact time with the coffee you can offset the effects of the reduced brew temperature.

This is the sound of the safety valve opening. This happens when the machine is heated too quickly (if it’s producing coffee in less than 3 minutes, it’s too quick), or if the water is unable to pass through the coffee. This is most commonly because the coffee has been ground too finely. See this page for further help.

Yes, this is normal. There is a narrow space, about 0.5mm wide where water will get trapped. If you want to remove this, you can follow the disassembly instructions here, then clean and dry the parts individually. This can be a good idea if you plan to leave the machine unused for an extended period of time.
