How To Use Delonghi Coffee Machine Explained: A UK Buyer's Guide

If you want to know how to use a De'Longhi coffee machine, start by filling the water tank, switching the machine on, waiting for the buttons to stop flashing, and then running a rinse cycle before brewing your first coffee. On a De'Longhi Lattissima, you then insert a Nespresso capsule, place your cup under the spout, and press your chosen drink button; for milk drinks, attach the milk carafe first and run the clean function straight afterwards.

Based on our testing with De'Longhi Lattissima machines in UK kitchens, most users get better results once they understand priming, milk setup, and volume programming rather than relying on factory defaults. Therefore, this guide explains exactly how to use your machine day to day, how to make milk drinks properly, and how to keep it working reliably for longer.

How do you use a De'Longhi coffee machine for the first time?

Before you make your first coffee, there is an important setup stage. In our experience, many first-use issues come from air in the internal pump or from skipping the rinse cycle. So, fill the tank to the 'Max' line with fresh water and make t is seated properly. If you live in a hard water area such as London or much of the South East, filtered water can help protect internal De'Longhi coffee machine parts.

What is the priming process on a De'Longhi Lattissima?

1. Plug the machine into a standard UK 230V socket and switch it on using the side power button.
2. Wait until the drink buttons stop flashing. Usually, this takes around 25 seconds while the thermoblock heats up.
3. Place a large mug under the coffee outlet with no capsule inserted.
4. Press the 'Lungo' button once to run water through the system.
5. Repeat this flush twice more if needed. This helps clear dust from manufacture and removes trapped air from internal pipes.

Once that is done, your machine is ready for normal brewing. As a result, your first coffee should pour more consistently and at the right temperature.

How do you make coffee with a De'Longhi Lattissima?

The everyday process is simple. First, lift the lever and insert a compatible Nespresso capsule. Next, place your cup under the spout and press either Espresso or Lungo. The machine pierces the capsule automatically and brews at pressure without any manual tamping or grinding. For busy households or home offices in the UK, that one-touch setup is one of the main reasons people choose Lattissima models.

Step-by-step: how to brew black coffee

1. Fill the water tank with fresh cold water.
2. Switch on and wait for all buttons to become steady.
3. Lift the lever fully and insert your capsule.
4. Close the lever securely.
5. Position an espresso cup or mug under the spout.
6. Press Espresso for a shorter shot or Lungo for a longer coffee.
7. Remove used capsules by lifting the lever after brewing so they drop into the used capsule container.

If your coffee tastes weak or overly short, check whether someone has reprogrammed your button volumes. You can reset or customise these settings easily, as explained below.

How do you use a De'Longhi coffee machine for milk drinks?

The standout feature of the De'Longhi Lattissima Touch is its Rapid Cappuccino System. Instead of steaming manually with a wand, you attach the milk carafe and let the machine foam and heat automatically. Consequently, it is much easier to get repeatable cappuccinos and latte macchiatos at home than with a manual setup such as a standard coffee machine with a manual milk frother.

How do you make cappuccino or latte on a De'Longhi Lattissima?

1. Fill the carafe: Use cold semi-skimmed or whole milk straight from the fridge. Based on our testing, colder milk produces denser foam than milk left at room temperature.
2. Attach it properly: Slide the milk carafe into position at the front until it clicks into place.
3. Aim the spout: Make sure both cup position and spout direction are correct before starting.
4. Select foam level: Turn the regulator knob on top of the carafe towards 'Min' for flatter drinks or towards 'Max' for thicker cappuccino foam.
5. Select your drink: Press Cappuccino, Latte Macchiato, Creamy Latte, Warm Milk or another available preset depending on your model layout.
6. Let it finish fully: The machine typically dispenses milk first and then brews espresso automatically.

Expert tip: Always press the 'Clean' button on the milk carafe immediately after making a milk drink. This quick steam purge helps remove residual milk from internal channels before proteins dry and harden.

This matters not only for taste but also for hygiene. According to UK food safety guidance around dairy handling in domestic kitchens, prompt cleaning reduces residue build-up and keeps chilled milk systems safer between uses.

How do you change drink size on a De'Longhi coffee machine?

A common question from UK users is how to make coffees slightly longer without compromising convenience. Fortunately, each tactile drink button on many Lattissima machines can be reprogrammed to suit your preferred mug size. So if standard espresso feels too short or lungo feels too small for your morning routine, you can adjust it in seconds.

How do you programme cup size on a De'Longhi Lattissima?

To customise volume, press and hold the button for your chosen drink. Keep holding until coffee reaches your preferred level in the cup, then release. The machine will confirm that new setting has been saved. After that, every time you press that same button briefly, it should pour approximately that programmed amount.

This feature is especially useful if you prefer larger UK mugs rather than smaller continental-style cups. However, avoid over-extending espresso capsules too far or flavour may become thin.
