A dirty coffee machine doesn’t just taste worse. It brews at the wrong temperature, clogs internal water lines, and wears out parts faster than a machine that’s properly maintained. Here’s the full two-step cleaning and descaling routine for the Saeco Minuto HD8763, plus how often to do it.

Why Cleaning Your Saeco Minuto HD8763 Matters

Every espresso and coffee shot leaves behind oil residue in the brew group. Every tank refill adds mineral deposits from water, especially in hard water areas. Left unaddressed, this buildup:

Blocks water flow through internal lines
Lowers brew temperature, which flattens coffee flavour
Increases wear on the brew group and heating element
Shortens the working life of the machine

Two products handle both problems: a cleaning tablet for the brew group, and a descaler for the internal water system.

What You’ll Need

Caffenu Universal Cleaning Tablets
Caffenu Universal Descaler
Fresh water
A container to catch runoff

Step 1: Clean the Brew Group

Fill the water tank with fresh water.
Add one Caffenu Universal Cleaning Tablet and let it fully dissolve.
Remove the brew group from the machine.
Soak the brew group in the solution for 15 seconds.
Rinse the brew group under running water until it runs clear.
Reinsert the brew group and close the service door.

This step targets coffee oil buildup and residue in the brew group specifically, the part of the machine that plain water rinsing doesn’t reach.

Step 2: Descale the Water System

Mix the Caffenu Universal Descaler to the ratio stated on the bottle.
Fill the water tank with the mixed solution and seat it back into the machine.
Run the solution through the milk frother outlet first.
Refill the tank with fresh water and run it through the coffee spout.
Refill the tank with fresh water a final time and flush it through both the milk frother outlet and coffee spout until empty.

Both outlets need separate flushing because scale builds up along both water paths, not just one.

How Often Should You Clean and Descale a Saeco Minuto HD8763?

Daily use or hard water areas: Clean weekly & descale every two weeks.
Standard use: clean weekly and descale every 2-3 months.

Frequently Asked Questions

How do I know if my Saeco Minuto HD8763 needs cleaning or descaling?

Signs include slower brew time, lower water flow, a metallic or flat taste, and visible white scale around the water tank or spout.

Can I use regular vinegar instead of a descaler?

Vinegar is not recommended for fully automatic machines. It can damage internal seals and doesn’t fully dissolve mineral scale the way a purpose-built descaler does.

Do I need to clean the brew group every time I descale?

No. Cleaning the brew group and descaling the water system are separate tasks. Clean the brew group weekly; descale on the schedule above based on water hardness and usage (Typically every 2-3 months).

What happens if I don’t clean or descale my machine regularly?

Untreated scale and oil buildup reduces brew temperature, blocks water flow, and increases the risk of expensive repairs or early machine failure.

It is no secret that only a clean machine makes the best coffee. Any barista can testify to that, but did you know that there’s more to cleaning an espresso machine than just giving it a wipe down after every use? Today we look at cleaning your espresso machine’s group heads.

The group head is one of the most important yet most overlooked areas of an espresso machine. It is extremely important to keep this area clean as this is where the coffee meets the machine. Here we set out a step-by-step guide for how you can maintain & clean your group heads.

Backflushing: To backflush your group heads you need to remove the filter basket from the handle and replace it with a blind filter, a filter without holes, or use a rubber disk to cover holes on filter basket. Place onto each group head and dispense water as if you are pulling a shot. Run the machine in this way for about 5 seconds and then stop. The blind filter will cause the water to pressurise so when you stop extracting, it will cause the water to flush back through the group screen and group solenoid (now you know why it’s called back flushing too!) and help to remove any coffee grounds and oils that have accumulated. Repeat 5 times for each group head and rinse 5 times with clean water. Do this daily if you resell your coffee or at home at least once a week with a cleaning agent. We recommend using the Caffenu Cleaning Powder when doing this. Doing this will greatly reduce any coffee oils in the group head & solenoid. Here is a full video that shows you how to use the Cleaning Powder on your espresso coffee machine.

Cleaning the group head gasket: It is a good idea to clean the group head gasket daily to help maintain a positive seal between the group head and portafilter. Best is to use the brush during your daily backflushing routine. Alternatively simply use hot water with the group head cleaning brush (such as the Caffenu Cleaning Brush) to vigorously scrub around the sealing surface.

Shower Screens: Even with regular backflushing, the group head shower screens must be replaced periodically but you can help them last a bit longer by screwing them off the group head and then soaking them in a solution of hot water and 1 teaspoon Caffenu Cleaning Powder or 1 Caffenu Cleaning Tablet. Scrub, rinse and refit. This will help break down the build-up of coffee oils.

Regular maintenance and cleaning of your beloved espresso machine goes a long way, not only in saving you money on replacements & services but also in ensuring you get the freshest cup of coffee, every time!
