How to Backflush your Ascaso Home Espresso Machine

An important part about owning an espresso machine is to make sure you clean and backflush your espresso machine.

What is backflushing?

Backflushing is a cleaning technique which forces water with the cleaning solution to flow back into the group to clear the internals from the residual coffee debris and build up.

Cleaning and backflushing your espresso machine will help to prolong the life of your espresso machine and make sure your espresso machine is working at its best and your coffee tasting at its best.

If the espresso machine is not backflushed (depending on the usage of the machine), it could cause debris and oil buildup which can harm the machine if the flow is completely blocked, it can cause components to fail or not work properly which will lead to the replacement of parts within the machine.

The Cafetto Tevo Mini Tablets help remove residual coffee oils, stains and grounds inside your machine which improves the taste of your coffee. Tevo Mini Tablets are great and handy as they are in portion controlled doses which are made easy to use. Not only do they work great, they are also organic, phosphate/GMO free, have a non corrosive formula to prevent damage to the machine, and they biodegrade rapidly to reduce the harm to the environment.

An alternative to the tablets is the Cafetto Evo Sachets. The Cafetto Evo Sachets are made of the same ingredients as the Tevo Mini Tablets, the only difference is that Evo is in powdered form which is rapidly soluble. They are also in conveniently pre-portioned sachets which make cleaning simple as opening the sachet and pouring it into your blind filter.
