How long does it take to heat up a coffee machine?

Most coffee machines that I sell heat up pretty quickly. Typical heat up time for a boiler is 5 minutes. This is followed by a little time for the metal in the machine to heat up. For a coffee machine with a fixed group this can take 5 minutes. For a coffee machine with an E61 group this can take 15 minutes.

If you are in a rush you get always speed up the heating time by running running water through the group. This is known as a warming flush. I can get any domestic coffee machine up to temperature in under 10 minutes with a warming flush.

Of course, the best solution for any coffee machine is to use a power point timer and set it up to switch your coffee machine on as you wake. You can even use a WiFi timer if you want to make your coffee machine “smart.”

Should I leave my coffee machine on all day?

Most Italian coffee machines that I sell are designed to be left on all day long. In fact, many of my professional home machines, such as the Profitec Pro 500, are used commercially in offices, coffee carts and restaurants.

The advantage of leaving your machine on is that it is “always ready.”

A disadvantage of leaving your machine on is power consumption. This is a very minor issue as most power is used during start up when heating your coffee machine from cold to hot. typical idling power consumption and running costs are tiny at several cents per hour.

Another minor disadvantage of leaving your machine on is extended exposure of internal components to heat. Although most machines are designed to be left on all day it is only logical to assume that lifetime of internal components will be improved if you turn your machine off when you are not using it.

I recommend that you heat your machine in the morning for your first round of coffees then switch it off and give it a rest. When at rest a heated machine will still stay warm for many hours so if you want another coffee a few hours later switch it back on and it will get up to brewing temperature really quickly.

Why isn't my coffee hot?

Firstly, the brew temperature of your Italian coffee machine has a negligible effect upon the temperature of your drink. Brew temperature will only effect flavour of your espresso. eg, colder for more acidity and warmer for more bitter sweetness.

Secondly, when steaming milk you should steam until the jug is hot to touch. Never overheat the milk as overheating will reduce the milk’s sweetness and it can even burn the milk.

The big secret to a hot drink is to pre-warm the cups with boiling water. With pre-warmed cups you will get a hot drink to enjoy.

What are the pressure gauges for?

Most Italian coffee machines have 2 gauges.

  • Gauge 1 - Steam boiler pressure (typically 1.1-1.2 bar, but up to 2 bar on high end dual boiler machines)

  • Gauge 2 - Brew pump pressure (typically 10-12 bar)

You will find the gauges interesting when you first get a coffee machine as they will help you to understand how the machine works. They are also useful to technicians during machine set up, and they can come in handy when diagnosing technical problems.

I’m often asked I watch the gauges when making coffee and the answer is no. I may glance at them occasionally but I don’t drive with them. Gauges on an espresso coffee machine are a little like gauges on a car. When driving either a coffee machine or a car you only don’t need to look at the gauges but it’s good to be aware of them and to understand when they are there for.

How do I use the lever on my E61 group?

Most manual Italian coffee machines have a lever operated E61 group.

When you first play you will notice 3 lever positions, but there are actually 4.

  • Position 1: down - water channel closed, pump off

  • Position 2: near 45 degrees - water channel channel closed, pump off

  • Position 3: near 25 degrees - water channel open, pump on

  • Position 4: up - water channel open, pump on

Positions 1, 2 and 4 are easy to find as they lock in. To find position 3 you need to have a play. Position 3 is where most E61 coffee machines will allow you to pre-wet the coffee puck when running off of a tank or to pre-infuse when running plumbed.

Sow you know how to pre-wet or pre-infuse. Next comes the important question: How useful are pre-wetting and pre-infusion? For the answer to this click here

When should I stop espresso extraction?

When using a manual Italian coffee machine you really need to understand espresso extraction. Don’t worry - I have made this simple.

To learn about espresso extraction and to understand the point where you stop extraction please visit my Understanding Espresso page.

After visiting my Understanding Espresso page simply follow my 10 Step Home Espresso Workflow on my Training Page and you will make amazing coffee time after time.

How do I use the portafilter baskets?

With most Italian coffee machines you will get a standard single basket and a standard double basket. I always recommend upgrading to a Precision Double Basket for the very best results.

Start with one of your double baskets (standard of precision) and avoid the single basket. The main reason for starting with a double basket is that with a double basket the coffee puck is thicker and less prone to water channeling. So start off with a double basket and master your espresso extractions.

After you have mastered your double basket extractions you can try out the single basket. With Italian coffee machines, using single baskets can be tricky to use because of the thin coffee pucks which are highly prone to water channeling. For this reason I highly recommend using a Coffee Distribution Tool

When it comes to dosing, the best approach for a single basket is to add the amount of coffee that gives you the same extraction speed that you get when using your double basket. You should find this sweet spot at around 12g. When you find the sweet spot you will be able to toggle between double and single baskets without any need to adjust the grinder setting.

Here is a guide to baskets:

  • Standard single basket - dose 12g of coffee and extract 20ml of liquid in 20s

  • Standard double basket - dose 16g of coffee and extract 30ml of liquid in 25s

  • Precision double basket - dose 20g of coffee and extract 40ml of liquid in 30s

What is the best brew pressure for espresso?

As with almost everything in this home barista hobby there is no indisputable “best.”

Many years ago a 9-10 bar brew pressure setting was typical for coffee machines. Now higher brew pressures are commonly used, with brew pressure settings for domestic Italian coffee machines ranging from 10-12 bar.

My best advice is to leave the pressure at the factory setting as the manufacturer will have your machine set for optimum performance. The pressure setting will have no noticeable effect upon the results in your cup so just leave your Italian coffee machine at the factory setting and brew away with confidence.  

Why is my espresso coming out too slowly?

  • Firstly, make sure that you are following every step of my Espresso Workflow

  • You may have too much coffee in your PF so check that the coffee dose is correct. Read my FAQ on Coffee Dosing

  • The coffee grind may be too fine so try a coarser grind.

  • Make sure that your tamp is even and firm.

  • Make sure that you are using fresh beans.

Why is my espresso coming out too fast?

  • Firstly, make sure that you are following every step of my Espresso Workflow

  • You may have too little coffee in your PF so check that the coffee dose is correct. Read my FAQ on Coffee Dosing

  • The coffee grind may be too course so try a finer grind.

  • Make sure that your tamp is even and firm, and only tamp once as over-tamping can break the coffee puck and cause channeling.

  • Check the grind distribution as poor distribution can result in water channeling and/or uneven extraction. For the best results I highly recommend using a Coffee Distribution Tool

  • Avoid supermarket beans. Supermarket beans are usually stale and this will generally result in quick, watery extractions. You can use them but tuning in your grinder can be tricky as you will need to adjust to a very fine setting.

Why is my espresso thin and watery?

Firstly, make sure that you are following every step of my Espresso Workflow

If you are getting a double espresso within 25-35 seconds and the espresso is thin and watery (without crema) there can be only one answer - the beans. Make sure that you are using fresh coffee beans. Beans less than 4 weeks old are recommended. To learn more about the importance of fresh beans read my FAQ on coffee bean Freshness and Storage

Do I need filtered water for my coffee machine?

Scale is a term used to describe mineral build up inside a coffee machine. Scale will build up on all parts of your machine that come into contact with hot water including boilers, heating elements, pumps and brew groups. Scale build up can cause a number of problems. Common problems are reduced boiler heating rate, reduced steam strength and reduced brew water flow rate.

  • If you have high quality tap water (eg, Melbourne) you can go ahead and use it. Most of my customers (9/10) use tap water. Of course, even with the best quality tap water you will still need to descale periodically.

  • If you have poor quality tap water I recommend installing a professional water filtration system, using rain water or using bottled water.

  • To learn about water filtration for Italian coffee machines click here

  • To learn about descaling domestic coffee machines click here

Note - Domestic coffee machine warranties do not cover damage caused by scale

Should I descale my home coffee machine?

Prevention is Better Than Cure

Standard water filtration via domestic drinking water filters (eg, Brita) removes particles and chemicals but does not removed the charged ions that cause scale build up. This type of filtration is not a great solution but it is certainly better than no filtration at all.

Some coffee machine (Profitec and Lelit) have an in-tank water filter option. These in-tank filters are designed to remove charged ions. They are moderately effective and they offer a cheap and easy way to reduce scale build up.

To prevent scale build up completely I recommend a professional water filtration system that removes particles, chemicals and charged ions. See my recommended water filtration systems for coffee machines here.

Rain water and bottled water are other options to consider for prevention of scale build up.

Cure

Most of my customers (9/10) use unfiltered tap water so this means that most of use choose cure instead of prevention. Unfiltered tap water can be used in your Italian coffee machine but all tap water contains charges ions that cause scale. This means that your machine will need to be descaled periodically.

DIY descaling

If you decide on a DIY descale only use dedicated coffee machine descaling solution. I recommend Caffetto cleaning products. Do not use citric acid. The reason for this is that dedicated descaling solution will gradually dissolve scale whereas citric acid will dislodge slithers of scale. These slithers can then get pumped through the machine and cause blockages. The risk of scale slithers is the reason that some coffee machine manufacturers do not recommend descaling.

Remember that coffee machine warranties do not cover damage caused by scale build up or damaged caused by scale dislodged during descaling. Descale at your own risk. There are risks to DIY descaling but if you follow my advice you will reduce this risk. If you decide to descale your machine here are the steps to follow.

  1. Turn the machine on and wait for it to heat up.

  2. Fill the water reservoir with descaling solution.

  3. Flush descaling water through the brew group.

    • Single Boiler Coffee Machine: Draws descaling solution from the water reservoir into the boiler and the brew group.

    • Heat Exchanger Coffee Machine: Draws descaling solution from the water reservoir into the heat exchanger and brew group.

    • Dual Boiler Coffee Machine: Draws descaling solution from the water reservoir into the brew boiler and the brew group.

  4. Flush descaling water through the hot water wand.

    1. Single Boiler Coffee Machine: Draws descaling solution from the water reservoir into the wand.

    2. Heat Exchanger Coffee Machine: Draws descaling solution from the water reservoir into the boiler.

    3. Dual Boiler Coffee Machine: Draws descaling solution from the water reservoir into the steam boiler.

  5. Leave for 60 minutes then repeat Steps 3-4.

  6. Fill the water reservoir with tap water.

  7. Flush tap water through the brew group.

    1. Single Boiler Coffee Machine: Draws tap water from the water reservoir into the boiler and the brew group.

    2. Heat Exchanger Coffee Machine: Draws tap water from the water reservoir into the heat exchanger and brew group.

    3. Dual Boiler Coffee Machine: Draws tap water from the water reservoir into the brew boiler and the brew group.

  8. Flush tap water through the hot water wand.

    1. Single Boiler Coffee Machine: Draws tap water from the water reservoir into the wand.

    2. Heat Exchanger Coffee Machine: Draws tap water from the water reservoir into the boiler.

    3. Dual Boiler Coffee Machine: Draws tap water from the water reservoir into the steam boiler.

  9. Dilute the descaling solution by repeating Steps 7-8 several times.

  10. All done. Time to enjoy a coffee.

Professional descaling

If you are uncomfortable with the risk of DIY descaling you should first look at prevention. You can prevent scale build up by using filtered water, rainwater or bottled water. If you can’t prevent the scale from building up and you don’t want to try out DIY descaling you can take your machine to a coffee machine technician periodically for professional descaling and servicing.

Descaling Frequency

Descaling frequency will depend upon the quality of your tap water quality and the amount of water that runs through your machine.

There’s no one answer here but here’s a rough guide for an Italian coffee machine running unfiltered Melbourne tap water. If you choose the DIY approach it is important that you descale regularly, before thick scale can build up. An annual DIY descale should do the trick. If you choose the professional descaling approach a professional descale every 5 years or so should be all that you need to keep your machine healthy.

Why is my pump / my gauge misbehaving?

I am often asked about pump and gauge behavior.

All Italian coffee machines that I sell have low water sensors that trigger automated boiler filling. This will occasionally occur when the machine is sitting idle, and when this happens the pump will switch on for 2-3 seconds for a quick top up.

Very occasionally a low water sensor will be triggered as the machine is pulling a shot. The result is a short (2-3 second) dip in brew pressure as the boiler gets topped up. This has no adverse effect upon the results in your cup.

Another observation that I am occasionally asked about is the fact that after pulling a shot the brew pressure gauge doesn’t set back to zero. This is because the brew pressure gauge measures pressure in the brew line, not pressure as the group head.

Why is my machine making weird noises?

Firstly, there is a range of “normal” noises for Italian coffee machines including squeaks, hums and rattles. Even when comparing brand new machines there is a range of sounds that can be considered as “normal.” As Italian coffee machines are made by hand, not my robots, every machine is a just little different.

Over time its normal for sounds (squeaks, hums and rattles) to change and to come and go. When it comes to new sounds I’m occasionally asked about new loud squeaks. Squeaking noises on coffee machines with E61 groups are often a sign that the E61 group needs a little more lubrication.

If you are handy and willing take a look on YouTube. You will find plenty of step-by-step videos that show you how to disassemble and re-lubricate your espresso machine’s E61 group. All you will need are some basic tools and some food safe grease. If you don’t want to get your hands dirty take it to a local Italian coffee machine technician for a quick, basic service. It won’t cost much.

Why does this sometimes happen earlier than expected? A simple reason. Too much back flushing with back flush detergent. Back flush detergent dissolves not only coffee oils, it also dissolves the good lubricating grease in the E61 group. For tips on how to maintain your machine without over-maintaining see my Italian coffee machine Maintenance Guide

Why won't my Italian coffee machine turn on?

First check that the coffee machine hasn’t run out of water as all of my Italian coffee machines will automatically turn off when the water level runs low. If water is in the water reservoir, turn the machine off, pull the tank out and put it back in to re-set the internal low water switch, then turn the machine on again. If it doesn't work the first time, try it again. Note that sometimes the water tank will need a little jiggle to reset the low water switch.

If the machine still doesn’t turn on and your machine has a magnetic float in the water tank (eg, Profitec, ECM) the float may be unseated. To fix this simply remove the housing cap, re-seat the float so that it freely slides up and down, then replace the housing cap. Make sure that the magnet on the float is positioned upwards.

Why isn’t the low water light turning off?

All Italian coffee machines that I sell cut off when the water tank runs empty to prevent the boiler/s from running dry. 

Most machines detect water by sensing conductivity between two detectors near the water intake. Some machines (eg, Profitec, ECM) use an in-tank magnetic float sensor in addition to the water conductivity sensor. The extra sensor is a fail safe mechanism. 

Many machines also have a low water indicator light. This will switch off when a water conductivity sensor detects low water. However, the indicator light will not switch off when a magnetic float sensor turns off the machine before the water conductivity sensor comes into play. This means that there are times when the tank is empty and the machine is cut off, but the low water light remains on indicating that there is water. This is normal.

The automated cut off is helpful but don’t rely upon it. Best practice is to keep the water level up and refill before the low water cut off is engaged. This prevents those dreaded mid extraction cut offs as well.

Why is there no flow or low flow from the group?

The most likely cause of no or low flow from an E61 group is a blockage caused by water scale. Coffee machines have many water pipes as well as small diameter restrictors that regulate water flow rate. Without water filtration these restrictors can block up regularly. Even with water filtration this issue may still occur from time to time. If you suspect that scale may be the problem, the best place to start is with the E61 group mushroom. Remove the mushroom, dismantle it and clear the small holes with a pin. Once you know how to do this it’s a simple 10 minute job.

Other possible causes of no flow from an E61 group are either a faulty pump or a faulty solenoid valve. Most coffee machines have solenoid valves which control water flow. Engaging the group lever causes these valves to open. When you engage the lever you should hear a click. If your don’t hear a click the valve may be stuck closed. Pump and valve problems are rare but they can happen.

Why is there water in the steam wand?

All steam wands on Italian coffee machines will have some condensed water sitting in the bottom when sitting idle. Before steaming, purge water for 1-2 seconds until you get to dry steam.

If you are using a single boiler coffee machine, check that you have switched from brew mode to steam mode, and also, waited for the boiler to reach steaming pressure (> 1 bar).

How do I keep my machine in great condition?

One of the great things about manual coffee machines is that they are very easy to maintain.

Prevention is always better than cure and there are a number of simple maintenance tasks to run through to keep your machine in tip top shape. By simple I really do mean simple. The most important aspect of maintenance is so keep your espresso machine clean by regularly rinsing and wiping. To learn more please make sure that you take a look at my visit my coffee machine Maintenance Guide

How do I get my machine serviced or repaired

Squeaks, leaks and changes to performance are signs that your coffee machine may need a service or a repair.

Most servicing and repairs are simple so if you are willing and qualified (electrical) you can contact me for advice or you can go online and search for guides. You can find almost everything. YouTube is amazing. If you are not willing and qualified (electrical) to service and repair your coffee machine you can take it to your local coffee machine technician or you can book an in-home service.

It’s always handy if you can go to a technician who specialises in the brand that you have but it isn’t necessary. Most coffee machine technicians can service any of the machines that I sell as the machines are all very similar and most share common parts from the same supply Italian supply chain. For advice on recommended technicians in your local area please get in Contact

How do I tune in a new coffee grinder?

Here are the steps to follow to tune in a new coffee grinder:

  • Grind some coffee and check the particle size.

    • If the particle size is large (like caster sugar) adjust the grind finer

    • If the particle size is small (like four) adjust the grind coarser

  • Continue until you get a particle size that is somewhere between caster sugar and flour.

  • Pull your first shot, watch the flow and take note of the time it takes to pour a 30g espresso.

  • Now follow the steps in my Espresso Workflow to fine tune the coffee grinder.

Note - As you move burrs closer together it is important that you plus the grinder at intervals. Failing to do this can result in coffee particles getting jammed between the burrs. These jammed particles can make the burrs seize.

How do I find the zero point of my coffee grinder?

It’s not necessary to find the zero point of a grinder but if you are interested in finding it then this is how you can do it:

  • Start with an empty and clean grinder.

  • Adjust the burr gap until the top and bottom burrs touch. This is the zero point.

  • Some expect the zero reading on the grinder to align with the zero point of the grinder but this is not the case. The numbers only used as a relative scale. ie, bigger number for a coarser grind and smaller number for a finer grind.

Why has my coffee grinder seized?

I see this from time to time. Don’t worry, it’s a very easy fix.

The main reason that this happens is that people move the coffee grinder setting from coarse to fine without pulsing at intervals, resulting in bean fragments getting caught between the burrs. The steps to fix this are:

  • Back the grind size off to very coarse.

  • Slowly work your way back towards espresso grind. As you adjust from course to fine it is important to pulse regularly to prevent seizing.

  • Fine tune the grinder for by following the steps in my Espresso Workflow

This will fix the problem in 9 out of 10 cases.

If you still can’t produce a fine grind and cannot turn the collar there is a chance that a foreign object, such as a stone, has that made it into the grinder. If you are qualified to work with electrical equipment your can follow the steps below to fix this:

  • Unplug the coffee grinder.

  • Remove the bean hopper.

  • Unscrew the grinder collar to remove the top burr.

  • Clean out the grind chamber by tipping the grinder upside down, brushing the burrs, brushing out the grind chamber and clearing out the exit chute using an unraveled paperclip.

  • Reassemble.

  • Fine tune the grinder for espresso by following the steps in my Espresso Workflow 

What is the best way to store coffee beans?

I’m often asked about coffee bean storage. A coffee bean is the seed of a fruit, and just as with any fruit, fresh is best. However, after roasting all beans need a short period for degassing. Here is a guide to when coffee beans are at their best after roasting:

  • Light roast: 5-40 days

  • Medium roast: 5-30 days

  • Dark roast: 5-20 days

The above timing is for coffee beans in open air. All beans will last a little longer if they are stored in bags with one way gas valves.

It's experience and the palate that tells the whole story but here's the theory to back up the results in the cup. Just as with any fruit exposed to oxygen there's quick degradation through oxidation. When beans are freshly roasted a nice amount of coffee oils are trapped inside the internal structure of the beans. As the beans age the internal structures breaks down and oils are released. These oils make their way to the bean surface and at the surface they oxidise to form a number of rancid compounds.

To protect coffee beans from oxygen they are usually packed into bags with one way gas valves within hours of roasting. These valves allow post roast off-gases to exit the bag, and as this happens the off-gasses push out the oxygen. This means that beans in a bag with a one way gas valve will stay fresh for much longer than beans in the open air because of their oxygen free environment.

It's a common misconception that it’s best to open a bag and take out just enough beans for a single dose, then reseal the bag to protect the rest. This isn't the case as when you open a bag you let oxygen in and when you reseal the bag you simply trap this oxygen. My advice is to keep bags sealed until you need the beans. When you open a bag just tip all of the beans into your hopper.
