The 4-key formula is used in all of their espresso machines, which improves every step from grinding to extraction and microfoam milk quality.

The Breville espresso machine, on the other hand, is not without its flaws.

There might be a blockage, or the grind setting could be incorrect in the machine.

It can happen that your machine is operating ok but no coffee is flowing out of the group head.

Here’s how to solve both of these issues.

Issue 1: Blockage in Group Head

If your Breville Barista Express happen to have a blockage in its group head, then you can try the following solution.

Backflush the machine on a regular basis to avoid clogging the control valve and leading it to underperform.

In a residential setting, backflush your machine without chemicals once a week and with chemicals after 200 shots, whichever comes first.

Backflushing should be done at the conclusion of each workday in a commercial setting.

Backflushing cleans the brew group, shower screen, and three-way valve.

In order to backflush your Breville espresso machine effectively, follow the instructions below.

1. Remove the filter basket and replace it with a backflush disc after disconnecting the portafilter from the machine.

2. In the basket, place the backflush cleaner.

3. Press the 2-cup button after re-entering the portafilter into the brew group.

4. Due to pressure build-up, the machine will become silent after approximately 20-30 seconds and eventually it will turn off.

5. Remove the portafilter when the cycle is finished and check to see if the pill has totally dissolved.

If this does not work, repeat the process without adding any cleanser.

6. Before filling the portafilter with coffee for later use, give it a good rinse.

Issue 2: Grinding Problems

When your machine possesses improper grinding problem, the there are few reasons for the same.

The first reason could be too fine grind setting.

The second reason could be related to the existence of excessive coffee in the basket if the machine isn’t pouring any coffee.

In such a case, you’ll need to modify the grind size and quantity to fix this grinding problem.

A. Set Proper Grind Size

First, you will have to find the grind size locator.

It ranges from 1 (very fine) to 16 (extremely coarse).

Set the grind size to five, however, you may change it later if necessary.

The coffee grind should be fine enough for nice espresso shots, but not powdered fine.

B. Adjust Proper Grind Amount

1. Locate the grind amount adjustment knob on the front of the machine.

2. Turn the knob counterclockwise to lower the grind amount and clockwise to raise it.

3. Set the grind amount to 3 o’clock and make any required adjustments.

This way, you will be able to adjust the grind amount as per your requirements.

If you properly set these two factors in your machine, then you will not face any grinding problems later on.

How Do You Unclog a Breville Barista Express Machine?

Most espresso machines have a water reservoir and filtration system in place.

They also come with steam and hot water nozzles that pour espresso and froth milk for specialty coffee beverages like cappuccinos.

Most espresso machines perform well with routine management and cleaning treatment.

If a clog or blockage arises, the equipment must be properly cleaned to remove that blockage and return to its normal operation.

Cleaning the unit after each usage while it is still warm is preferable.

Because it is pretty hard and tedious to clean the machine after the debris has hardened and saturated inside the parts of the machine.

Regardless of the manufacturer, troubleshooting a Delonghi, Breville, or Krups espresso machine follows the same cleaning routine.

5 Important Steps to Unclog the Breville Barista Express Machine

Step 1: Clean the Machine

To proceed, remove the filter holder and clean the filter of any coffee grounds.

Remove the filter basket and carefully rinse it.

Replace the filter basket in its original position.

Now, to detach the sleeve, unscrew the screw that keeps the steam valve in position and drop down on the steam valve.

To eliminate any powdered creamer residue or other things, it is important to clean it properly.

You can wash the sleeve with warm or hot water and detergent along with a cleansing sponge.

Step 2: Run the Steam

Steam is one of the most effective techniques for removing a blockage from an espresso machine.

Fill a cup halfway with water and place the steam wand inside the frother to make it function.

Allow the water to froth for a few seconds after turning the Steam Selector knob to the “Steam” option.

Switch off the steam selection.

Now, remove skim milk powder from the steam nozzle with a long pin if the nozzle is not steamed.

Close the lid by sliding the sleeve back onto the steam valve.

Step 3: Clean Brew Filter and Unit

Clean the unit and hold the handle.

Now, by pressing the release button, get the brew unit out.

Clean it using a sponge and warm water.

Do not use any type of dishwasher liquid to prevent unwanted results.

Also, clean the permanent filter in the funnel using a clean sponge to remove any coffee grounds.

Dry the funnel and return brew unit back to its original position.

To decalcify the nozzle, repeat the process three times.

Remove the steam nozzle from the machine and dry it with a cloth.
