But here’s the thing: even the best machines won’t last if they’re not properly maintained.

Today, I’ll show you everything you need to do to keep your Ascaso duo steel running like new, from quick daily routines to long-term care that will save you from expensive repairs.

I’m going to divide this blog post into a step-by-step guide for the Ascaso duo steel, what to do daily, weekly, and every few months.

How to Clean Backflush Ascaso Steel Duo

Let’s start with the basics. These are the things you should be doing every single day, ideally, after each session.

Flush the Group Head

Flush the Group Head after pulling your shot of espresso, run some water through the group head for five to 10 seconds.

This removes leftover coffee oils and grinds from the shower screen.

Oils build up fast, and they do affect the taste of your coffee.

So, make sure that your group head is clean.

Wipe and purge the steam wand

Wipe and purge the steam wand immediately after steaming milk, and then wipe it down with a clean cloth.

Please do this every single time after using the steam wand, after wiping it, and purging steam for a few seconds.

Milk residue can harden quickly and block the tip or cause bacterial growth, which we obviously do not want.

Oh, and just so you know, no coffee or milk

How to clean Ascaso Steel Duo

Insert the blind filter basket into your portafilter, lock it in, and run the pump for around 10 seconds.

This also helps to clear out any coffee oils or coffee particles inside your Ascaso Steel Duo PID machine, and keeps your machine running smoothly.

Here you can see me back-flushing the Ascaso Steel Duo PID coffee machine.

The Ascaso steel machine builds up pressure like it would when making espresso, but because of the blind basket

the water runs back through the machine and goes directly into the drip tray, which I try to empty daily as well.

For great-tasting coffee, it’s important to keep your brewer running at peak performance! The Descale & Cleanse Starter Kit is the perfect way to try some of the essential cleaning items that Keurig® offers to maintain your brewer.

I recommend using a cleaning tablet made for espresso machines, they’re specifically designed to break down coffee oils without damaging internal components

add the cleaner into the blind basket, lock the porta filter in, and pull a shot for around 10 seconds.

This is what it looks like after the first time.

Now I repeat this three to five times, then I pour out everything that’s left in the blind basket.

Now I repeat the cycle again, but with an empty and clean blind basket.

I also do this two to three times just to make sure that there is no cleaner left inside.

Now, you know how to do a proper back flush with a cleaning tablet.

Next up, we have something you don’t need to do often, but it’s absolutely essential for long-term performance.

How to Ascaso Steel Duo descale instructions

Descaling even with filtered water, scale builds up inside the boiler or thermal block, and over time,

It can clog the system, reduce pressure, and even burn out your heating element.

I’m going to show you how to descale your Ascazo steel duo PID. Make sure the machine is cool before you start to descale the machine.

The Ascaso Steel Duo descale instructions first step is to turn the machine on.

Now you have to push and hold both buttons of your machine until the setup menu shows up.

Then you have to navigate through the menu using the left button until you see CLN, which means cleaning.

Then you have to push the right button to choose CLN, which shows off.

Then you just push the right button again, and now it says, See on after a few seconds, it switches to CLB.

And now you have to wait until the light under the shot switch stops blinking and lights up constantly.

While we wait, we mix a descaling solution.

Just follow the Ascaso Steel Duo PID instructions on your product.

My descaler says to put in 100 milliliters per one liter of water, then pour the mixture into the water tank.

I’ve done this two times, so I ended up with around two liters of water and 200 milliliters of Ascaso descaler.

Then after a few minutes, the light stopped flashing, which means we are ready to go.

Now I place a large container under the group head, and then we let our solution run through the group head.

Then, after some time, I attach the portafilter with a blind basket and do a little back flush.
